FATAL CASES OF INHALATION OF CHLOROFORM.
If it were possible for a medical man to mistake or disregard the symptoms of approaching danger, and to go on exhibiting vapour of chloroform, diluted to a proper strength, till the death of the patient, this event would take place slowly and gradually, as in Experiment 23, related above, and every other experiment in which the air did not contain more than five per cent. of vapour. The action of the heart would survive the respiration; there would be a great tendency to spontaneous recovery, and the patient would be easily restored by artificial respiration, if it were performed whilst the heart was still acting; as I have always found it to be successful in animals under these circumstances.
In examining the recorded cases of fatal inhalation of chloroform, we shall find, however, that they have none of them taken place in this gradual manner; but that in all cases the fatal symptoms, if not the actual death, have come on very suddenly. Dr. Sibson was, I believe, the first to point out that, in the fatal cases of inhalation of chloroform, death was caused by its paralysing the heart; but he was not at that time aware of the physical conditions under which this agent may act directly on the heart. In commenting on the first four deaths from chloroform, he says:[[61]] “In all the four cases it is manifest that the immediate cause of the instantaneous death lay in the heart. The heart, influenced by the poison, ceased to contract, not from the cessation of respiration, for the heart in asphyxia will beat from one to three minutes after respiration has ceased, but from immediate death of the heart. There is no doubt a combination of causes operating to destroy the heart’s contractile power: the mental influence, the congestion in the systemic, and that in the pulmonary capillaries, will all have a material influence.” And further on he says: “We are obliged, then, from the experience of these cases, to conclude, that in man the death is usually instantaneous, and due, as every instantaneous death is, to paralysis of the heart. In animals the death is usually due to paralysis of the muscles of respiration. It is chiefly owing to the superior control of the mind over the body in man, that in him the poison acts on the heart more than in dogs.”
I had been long aware that chloroform was capable of paralysing the heart in animals; and, indeed, that sulphuric ether would do so when it could reach the heart in sufficient quantity;[[62]] and soon after Dr. Sibson’s remarks I was able to ascertain and point out the strength of the vapour which will produce this effect, and how one may avoid the risk of it, by having the vapour sufficiently diluted.[[63]] The greater number of experimenters who have killed animals with chloroform have found that the action of the heart continued after the breathing ceased; but they did not either control or ascertain the proportion which the vapours of chloroform bore to the inspired air. In Mr. Thomas Wakley’s experiments the action of the heart continued after the breathing had ceased; and this was the case in a great number of experiments performed by a Commission which reported to the Society of Emulation of Paris, in 1855.[[64]]
This Commission came to the conclusion that, in all instances in which animals are killed by chloroform, the action of the heart survives the respiration; but they might have administered chloroform to an equal number of human patients without any one of them being cut off by sudden paralysis of the heart. If animals were usually to die suddenly of paralysis of the heart, when the chloroform is given in a manner similar to what may be called its ordinary administration to patients, we should be at a loss to know how this agent could be used at all. It is only reasonable to suppose that, in experiments so conducted, that mode of death should usually be met with which would occur to the human subject, if the chloroform were continued, in the disregard of dangerous symptoms, till death should ensue. I have, indeed, been informed of several instances in which animals died in a sudden, and what was thought an unaccountable manner, whilst chloroform was given to prevent the pain and struggles which would be occasioned by physiological experiments. In these cases there is no doubt the heart was paralysed; but the experimenters were often too intent on other matters to observe the circumstance. By a proper arrangement of circumstances, however, one may produce at will the event in animals which occurs, in fact, so very rarely to a patient, although it may at any time happen if great caution, guided also by right principle, is not used.
Air, when saturated only at 60° Fah., contains 12 per cent. of vapour of chloroform, and at 70° 19 per cent. (p. 33); and 8 or 10 per cent. in the inspired air is capable, as we have seen, of causing sudden death by paralysing the heart; but in practice the air is usually far from being saturated, in passing over a handkerchief or similar material, even at the temperature at which it is inhaled; and this is generally lowered considerably by the absorption of caloric by the chloroform, as it changes its condition from a liquid to a vapour. Moreover, air strongly charged with vapour of chloroform is not easy to breathe, owing to its pungency; and the physiological knowledge and close attention of every medical man who administers this medicine causes him to withdraw it immediately on the least appearance of danger.
Case 1. The first death from chloroform was that of Hannah Greener, which occurred at Winlaton, near Newcastle, on the 28th of January, 1848. The patient was a girl of 15, who required to have the nail of the great toe removed. A similar operation had been performed on the other foot, in the previous November, in the Newcastle Infirmary, when ether was administered with a satisfactory result. The following is the account of the accident by Dr. Meggison, who administered the chloroform: “She appeared to dread the operation, and fretted a good deal: in fact, she commenced sobbing on our entering the house, and continued so until seated in the operating chair, and commencing the inhalation, which was done from a handkerchief on which a teaspoonful of chloroform had been poured. After drawing her breath twice, she pulled my hand from her mouth. I told her to put her hands on her knees, and breathe quietly, which she did. In about half a minute, seeing no change in breathing, or alteration of pulse, I lifted her arm, which I found rigid. I looked at the pupil and pinched her cheek, and, finding her insensible, requested Mr. Lloyd to begin the operation. At the termination of the semilunar incision she gave a kick or twitch, which caused me to think the chloroform had not sufficient effect. I was proceeding to apply more to the handkerchief, when her lips, which had been previously of a good colour, became suddenly blanched, and she spluttered at the mouth, as if in epilepsy. I threw down the handkerchief, dashed cold water in her face, and gave her some internally, followed by brandy, without, however, the least effect, not the slightest attempt at a rally being made. We laid her on the floor, opened a vein in her arm, and the jugular vein, but no blood flowed. The whole process of inhalation, operation, venesection, and death, could not, I should say, have occupied more than two minutes.”[[65]]
An examination of the body was made the day after death by Sir John Fife and Dr. Glover, who reported as follows:—“The body was that of a well-grown female of about fifteen years of age.... On opening the chest, the lungs were not collapsed. One or two very slight adhesions were encountered on separating them from the walls of the chest. The external appearance of both lungs, over the whole surface, but especially in the inferior portions, was that of organs in a very high state of congestion. They were mottled with patches of a deep purple, blueish, or scarlet hue. They were everywhere crepitant. Along the outer and interior border of both lungs, particularly of the upper lobe of the left lung, were several emphysematous bubbles of small size.... The pulmonary tissue was filled with bloody froth, which was also found in the interior of the bronchi, mixed with mucus. There was no appearance of hepatization. On examining the larynx and trachea, the epiglottis was found reddened at the summit, of a vermilion hue. The mucous membrane of the larynx was redder than natural—mottled with vascular patches. The sinuses of the larynx contained a good deal of dark mucus. The œsophagus was healthy. The stomach was distended with food. Some of the veins were more distinct than usual. The heart contained dark fluid blood in both its cavities: very little in the left. Its structure, and that of the great vessels near it, quite healthy. The brain, externally and internally, was more congested than usual; and the ventricles contained rather more than the usual quantity of serum.”[[66]]
Sir John Fife and Dr. Glover expressed the opinion that chloroform caused death by producing congestion of the lungs. After the further experience which has been gained respecting chloroform, this opinion of the mode in which it caused death, in the above case, would probably not now be offered. Indeed, in similar cases which have since occurred, the same opinion has not been advanced; and as the lungs were crepitant throughout, in the above case, it is probable that the congestion was not greater than is commonly met with in cases of sudden death without hæmorrhage. Dr. Simpson published his opinion, immediately after this case occurred, that it was not caused by the chloroform, but by the brandy which was given when the alarming symptoms came on; but Dr. Meggison replied that only a teaspoonful of brandy was given; that it was swallowed, though with difficulty; that there were no symptoms of choking from it; and that the girl was without pulse when it was given.[[67]]
From the lips becoming suddenly blanched in the above case, there is every reason to conclude that the heart was suddenly paralysed. The patient breathed for a little time after this, and was able to swallow, though with difficulty. The process of inhalation occupied only a little more than half a minute in Dr. Meggison’s estimation; yet he appeared to think that the fluid drachm of chloroform which he had put on the handkerchief had evaporated; for he was about to apply more when the alarming symptoms appeared. But supposing only one-third of the drachm was actually inhaled into the lungs in the half minute, the vapour would necessarily be in a highly concentrated state—probably twenty cubic inches of vapour in 200 cubic inches of air, which would be adequate to occasion the result which happened. In the short space of about half a minute, the blood could not be uniformly impregnated with the vapour; only a portion of it could pass through the lungs in the time; yet, as the patient was rendered insensible, this portion must necessarily have been highly charged with vapour.
It was often the practice to render the patient insensible in as short a time as half a minute, when chloroform was first introduced, but I believe never without danger; and I had expressed the opinion before any accident happened, that, for reasons such as I have stated above, a patient should on no account be rendered insensible in less than two minutes.[[68]]
Case 2. The next recorded case in which the inhalation of chloroform was fatal, occurred at Cincinnati, on the 23rd of February, 1848. The subject of it, Mrs. Martha G. Simmons, was thirty-five years of age, and enjoyed good general health; she was the mother of six children, and her last confinement occurred eight weeks before her death. The patient exhibited no alarm on account of inhaling the chloroform, which was administered by two dentists, who were not members of the medical profession. It was breathed from an inhaler which Dr. Morton of Boston contrived for sulphuric ether. This inhaler consisted of a glass globe four inches and a half in diameter, and contained a sponge about one-third filling the globe, and saturated with chloroform.
Two female friends of the patient reported the following as the events which occurred. “The respiratory movements appeared to be free; chest heaving. While inhaling, the face became pale. At the expiration of about one minute, the instruments were applied, and four roots of teeth extracted. The patient groaned and manifested what they regarded as evidences of pain, while the teeth were being extracted, although she did not speak or exhibit any other sign of consciousness. As the last root came out, which was about two minutes from the beginning of the inhalation, the patient’s head turned to one side, the arms became slightly rigid, and the body drawn somewhat backwards, with a tendency to slide out of the operating chair. At this instant, Mrs. Pearson states that she placed her finger upon the patients pulse; observed that it was feeble, and immediately ceased to beat; respiration also ceased about the same time. The face, which was previously pale, now became livid, as did also the finger nails; and the lower jaw dropped, and the tongue projected a little at one corner of the mouth, and the arms were perfectly relaxed. The females regarded her as being then quite dead.”[[69]]
The dentists gave nearly the same account, saying that the breathing was at first slow, and that the patient inhaled twelve or fifteen times, occupying from a minute to seventy-five seconds. They committed the great error of not placing the patient at once in the horizontal position, when the alarming symptoms came on, but kept her sitting in the chair, from five to ten minutes, whilst they sent out for restoratives. They thought the patient was living during this time, but her female friends thought not. The patient was placed on a sofa, and sometime afterwards artificial respiration and galvanism were applied without effect.
An examination of the body was made twenty-six hours after death by Drs. Mussey, Lawson, Baker and Mulford. The following are the chief particulars of the appearances met with. A larger quantity of blood than usual flowed from the sinuses of the dura mater. General aspect, colour, and consistence of the brain, normal. Lungs considerably but not intensely congested; crepitated freely at all points; no extravasation. Lining membrane of bronchia slightly congested, apparently the result of recent catarrh; deeply stained by the blood. Pleura at all points highly injected; six drachms of bloody serum in the right, and two ounces in the left chest. Pericardium contained six drachms of bloody serum. Heart flaccid, and all its cavities entirely empty; inner surface of both ventricles and auricles deeply stained. Abdomen—one ounce and a half of bloody serum in the right hypochondrium. Stomach and intestines distended with gas. Partially digested aliment, amounting to about three gills in the stomach. Blood fluid as water in every part of the body; not a coagulum was seen in any vessel. Lining membrane of all the bloodvessels deeply stained. The colour in every part of the system was that of dark venous blood.
It was estimated, in the inquiry which took place respecting this case, that one-fourth part by measure of what the patient inhaled might be vapour of chloroform; but this is evidently an over-calculation, for there could not be this quantity unless the interior of the glass globe were maintained at the temperature of 80° Fah. and the air were quite saturated with vapour in passing through it; however, less than half the amount of vapour here assumed would have the effect of causing sudden death, in the way it happened. The period of the inhalation, a minute or seventy-five seconds, during which the patient took twelve or fifteen inspirations, did not admit of the blood in the body being regularly and uniformly charged with the chloroform; and the increase of its effects, owing, no doubt, to the absorption and circulation of the vapour contained in the lungs at the moment when the inhalation was discontinued, was well marked. The patient became pale during the inhalation, but the alarming symptoms suddenly came on during the extraction of the fourth stump, probably within half a minute after the inhalation ceased. The patient seemed, in fact, to die with the slight struggle that took place at this moment. In the case of Hannah Greener, related above, the spasm at the moment of dying was even more marked. This is a symptom I have often seen during the death of animals killed suddenly with vapour of chloroform in a concentrated state, before they were made thoroughly insensible. Although the heart was empty, the stained condition of its cavities showed that they had contained blood at the time of death and afterwards. Owing to its fluid state, it probably escaped from the heart during the moving of the body; especially during the examination of the head, which was made first.
Case 3. The next recorded case of death from chloroform is reported by Dr. John C. Warren, of Boston, U.S., in the London Medical Gazette.[[70]] His report, apparently extracted from some other report, is as follows.
“Name—Patrick Coyle. [Age—not stated.] Date—March 1848. Disease—fistula. Previous use of chloroform—once. Time of inhalation—about one minute. Quantity consumed—about thirty drops. [Query minims.] Posture—upon the side. Lapse of time till death—about one minute. Symptoms—showed signs of pain, by putting his hand to the part; in a moment his pulse, which was full and natural, sank: death. Morbid appearances—brain, with membranes, natural and healthy. Heart enlarged, pale, and soft; two or three ounces of serum in pericardium; bloodvessels with dark fluid blood. Lungs, studded with tubercles; abscess in each; lower parts congested; pleura extensively adherent; stomach—mucous membrane softened, its veins turgid.”
Nothing is said about the apparatus used in this case, but from the summing-up of Dr. Warren’s paper, it must have been either a towel or a handkerchief. The quantity of chloroform employed appears to have been much less than in the two previous cases. In speaking of drops, the writer probably means minims, or what is the same, a quantity equal to as many drops of water. Thirty drops of chloroform from a small phial are only equal to between six and seven minims, and if they were dropped on a handkerchief, so that they might be counted, they would evaporate entirely during the process. Supposing the quantity used to have been what is probably meant—half a fluid drachm—it would be quite adequate, according to calculations previously made in these pages, to cause the accident which happened. The period of inhalation was again very short—one minute; and the evidence of paralysis of the heart is distinct:—“In a moment his pulse, which was full and natural, sank: death.”
Case 4 was that of Madlle. Stock, aged thirty, and occurred at Boulogne, in May 1848. The operation was that of opening a sinus in the thigh, between two and three inches in length, at the bottom of which a small splinter of wood was found. M. Gorré, the surgeon who attended the patient, says: “I placed over the nostrils of the patient a handkerchief moistened with fifteen to twenty drops of chloroform at most.” It is necessary to remark, however, that a judicial examination of the bottle from which it had been taken, proved that from five to eight grammes had been used, a quantity equal to from 77 to 123 grains, and there are three drops of chloroform to a grain. M. Gorré proceeds to say: “Scarcely had she taken several inspirations, when she put her hand on the handkerchief to withdraw it, and cried with a plaintive voice, ‘I choke.’ Immediately the face became pale; the countenance changed; the breathing embarrassed; and she foamed at the mouth. At the same instant (and certainly less than a minute after the beginning of the inhalation), the handkerchief moistened with chloroform was withdrawn.” M. Gorré performed the operation, but he expressed the opinion afterwards that death had already taken place when he made the incision. Amongst the means used, with a view to resuscitate the patient, was inflation of the lungs, which was performed with such force as to produce permanent dilatation of the air-cells. The lungs, besides being distended from this cause, were found after death to be visibly engorged in their lower lobes. When cut into, a large quantity of black blood escaped. The cavities of the heart were empty, but the internal membrane, especially of the right cavities, was red. The tissue of the heart was pale, and was easily torn. Air was found in the pulmonary veins, and in most of the systemic veins throughout the body. The blood was very dark-coloured and fluid.[[71]]
M. Gorré reported the above case to the Academy of Medicine of Paris, and a commission was appointed to inquire and report on it, who came to the following conclusions.
“1. In the medico-legal fact submitted to our notice, we found no indication of the poisonous action of chloroform; and consequently we reply to the minister, that the patient of M. Gorré did not die from the effect of inhalation of that agent.
“2. There have occurred a great number of analogous cases of sudden and unforeseen death, during operations, without any administration of chloroform, in which the most minute examinations have failed in detecting any assignable cause of death.
“3. In the case in question, the most probable cause, under all circumstances, seems to have been the mixture of a considerable quantity of gas with the blood.”[[72]]
The report on this case gave rise to frequent discussions in the Academy, extending over several months, and the Academy ultimately confirmed the above conclusions, but not without considerable opposition from M. Blandin, M. Jules Guérin, and other members.
M. Malgaigne, the reporter to the commission, and others, who strongly supported the first of the above propositions, founded their argument chiefly on the assertion that chloroform always produces intoxication and insensibility before death; but this is incorrect, as I have explained above; and I took occasion to make the following remarks on this point about the time when the discussion in the Academy of Medicine took place. I said: “I have several times made animals—small birds, mice and rabbits—breathe air saturated with vapour of chloroform at the temperature of the atmosphere, and the consequence has always been that, after attempting for a few seconds to escape from the capacious jar in which they were enclosed, they suddenly exhibited signs of distress, and died without any interval of intoxication or insensibility, in periods varying from less than half a minute to a minute after their first exposure to the vapour.”[[73]]
The power of chloroform to cause sudden death without previous insensibility is now, I believe, generally admitted. The French call this kind of fatal action sideration.
With regard to the second conclusion of the commission, if it had been really true that the surgeon put only fifteen to twenty drops at the most of chloroform on the handkerchief, one would have been inclined to admit it; but with the quantity actually employed, and the strong sensation of choking it occasioned just before death, one must, in connection with other cases, and with what is known of the action of chloroform, attribute the fatal event to this agent, rather than to the surgical operation, which was not of a serious nature.
With regard to the third of the above conclusions, it is not a little remarkable that most even of those speakers who opposed the conclusions of the commission, agreed that death was caused by a sudden development of air in the veins; and differed from them only in this, that they considered the chloroform as the cause of the evolution of air or gas, and that it proved fatal in this way. That the air was not caused by putrefaction, and that it did not enter by the wound in the thigh, may be readily admitted, but there remains the artificial respiration, which was performed with such force as to produce permanent dilatation of the air-cells. It was argued in the Academy that, as the air was in the systemic, as well as in the pulmonary veins, it could not have been introduced by the artificial respiration, since the left ventricle had previously ceased to act; but the action of the left ventricle is not necessary for the passage of the contents of the arteries through the capillaries into the veins, since this commonly goes on after death, the arteries being usually found entirely empty of the blood they must have contained at the moment of death. With regard to the passage of the air out of the heart into the arteries, supposing that the pulmonary veins were ruptured during the inflation of the lungs, there is an observation of Dr. Sibson’s which will explain both this circumstance and the fact of the heart itself being found empty of blood. He found that the heart was often emptied of blood by distending the lungs with air after death in preparing the body for his diagrams of the position of the viscera.[[74]]
With the conclusions above quoted, some additional ones were adopted from the second part of the report of the commissioners; in these it was admitted that chloroform is capable of causing death, if administered too long, or in too large doses. One of these additional conclusions, however, is as erroneous as the previous ones. It is, “there is risk of asphyxia when the anæsthetic vapour is not sufficiently diluted with air.” When the vapour is not sufficiently diluted with air, the risk is one of sudden death, by paralysis of the heart. Chloroform does not yield enough vapour, at the natural temperature and pressure of the atmosphere, to exclude the air to the extent which would cause asphyxia. When chloroform vapour largely diluted with air is long continued, it may cause, not real asphyxia, but a mode of death resembling it, owing to the medulla oblongata and nerves of respiration becoming over narcotised.
Case 5 is that of a young woman at Hyderabad, who inhaled chloroform to undergo amputation of the middle finger. A drachm was sprinkled on a handkerchief and inhaled. The operator described what occurred as follows: “She coughed a little, and then gave a few convulsive movements. When these subsided, I performed the necessary incisions, which of course did not occupy more than a few seconds. Scarcely a drop of blood escaped.” The absence of bleeding seemed to be the circumstance which called the attention of the operator to the state of his patient; and after describing the means which were used without avail to bring about recovery, he continues, “I am inclined to think that death was almost instantaneous; for, after the convulsive movements above described, she never moved or exhibited the smallest sign of life.”[[75]]
In this case, it is probable that the breathing and the action of the heart were both arrested at the same time, by the action of the chloroform.
Case 6. Charles Desnoyers, aged twenty-two, a patient in the Hôtel-Dieu at Lyons, affected with scrofulous disease of the left wrist, having to undergo transcurrent cauterisation of the joint, inhaled chloroform from an apparatus for five minutes, and died at the beginning of the operation.[[76]] Further particulars are not given.
Case 7. A young gentleman, who had returned from Australia to visit his relatives in the neighbourhood of Govan, inhaled chloroform for an intended operation on the great toe, in December 1848. It is stated that the patient, after inhaling it, almost instantly expired. This account appeared in the Glasgow Herald, and was copied into the medical journals.[[77]] I believe that no further account of the case was ever published.
Case 8 occurred on January 19th, 1849. It is related by Dr. John C. Warren.[[78]] John Griffith, an Irishman, aged thirty-one, a seaman in the American navy, was admitted into the New York Hospital early in December 1848, on his return from Mexico. He was suffering with diarrhœa, chancres, and hæmorrhoids. The following is the account of this accident.
“Gurdon Buck, jun., attending surgeon to the New York Hospital, being sworn, says, that ‘on or about the 26th of December, I advised that chloroform should be administered to the deceased, for the purpose of examining the condition of the rectum, the parts being in such a state of excessive irritation as scarcely to admit of a separation of the nates. The patient recovered from the effects of the chloroform, and remained in all respects in the same condition, except the local ailments spoken of; and he having never complained of either his head or his chest, and not having suffered from the first administration of chloroform, I directed it to be administered to him for the purpose of performing an operation upon the rectum, and the operation of circumcision to remove a phymosis caused by the chancres: the patient soon became excited by the chloroform, as is usually the case, but not beyond a degree that I have often observed. Shortly after, he became more tranquil: the deceased was placed upon his side, and the operation performed, which consisted in the removal of two external tumours, and the tying of one internal tumour.
“‘At this moment my attention was arrested by my assistant’s calling for a wet cloth: on examining the patient, I found his face and neck of a livid leaden hue or colour, the eyes turned upward, the pulse imperceptible at the wrist, and the whole body relaxed; after two or three gasps, he ceased to breathe. Every means was promptly used to restore the deceased, but without effect. The chloroform was obtained from Kent’s, 91, John Street, and not exceeding three drachms was administered on a napkin. A portion of chloroform from the same phial had been administered the day before to a patient without any unfavourable effects. About ten minutes elapsed from the commencement of its administration before death took place. On making a post-mortem examination, twenty-four hours after death, I found the face less livid than before death; on examining the head, the brain and its membranes presented no other appearances than are seen in persons dying when in full health; the lungs were a good deal congested, and discharged, when cut, a large quantity of bloody serum; the heart was large, its ventricles and auricles were empty, its condition flabby, the substance of the left ventricle rather softer than natural; about half an ounce of watery fluid was found in the pericardium; the viscera of the abdomen were healthy.’”
This case differs from those previously related in respect to the time at which the fatal occurrence took place. It was not till ten minutes from the commencement of inhalation, and when an operation which probably occupied two or three minutes had been performed, that the patient suddenly expired. The evidence of paralysis of the heart is, however, distinct enough in the absence of pulse at the wrist, and the livid hue of the countenance. In several of the previous cases, there was sudden pallor at the moment when the heart ceased to inject blood into the capillaries, but in a patient well supplied with blood, the sudden arrest of the action of the heart would cause turgescence of the veins and venous capillaries, which would be evident in the face in a few seconds. The syncope occasioned by paralysis of the heart differs from that kind of syncope which is caused by loss of blood, inasmuch as the right cavities of the heart are full in the former instance, and empty in the latter.
The circumstance of the patient having inhaled chloroform to insensibility three weeks previously, without accident or ill effects, is worthy of notice, as showing that the fatal event did not depend on any peculiarity of constitution.
Although the heart was found to be empty, its flabby condition and the watery fluid in the pericardium indicate that it must have contained blood at the time of death.
Case 9 occurred on January 24th, 1849, at the Hôtel-Dieu, Lyons, where case 6 previously happened. The patient was a youth, aged seventeen, named J. Verrier, who had been employed as a miner. He was of good constitution, and was about to undergo amputation of the middle finger for necrosis of the first phalanx. The following is the account of the accident.
“As the patient’s health was good, he was at once, and by his free consent, placed under the influence of chloroform. As usual, a piece of fine gauze was employed; it was spread over the face, leaving a free passage for atmospheric air; the chloroform was dropped from time to time upon that portion of the gauze which was over the nostrils. It was administered by two assistants who were accustomed to its use, and who at the time attended to the pulse. The operator superintended the assistants. At the end of four or five minutes, the patient still felt and spoke; and at the end of another minute, he still spoke and was somewhat restless. Up to this time, from a drachm to a drachm and a half of chloroform had been employed. The pulse was regular, and of the normal strength. All at once the patient raised his body, and struggled so that the limbs escaped from the hold of the assistants, who however seized them quickly, and replaced the patient in his position. Within a quarter of a minute, one of the assistants stated that the pulse at the wrist had ceased to beat. The handkerchief was removed. The countenance was completely altered. The action of the heart had altogether ceased; the pulse could not be felt anywhere; and the sounds over the region of the heart could no longer be heard. Respiration still continued, but it became irregular, weak, and slow; and at length ceased completely in the space of about half a minute.
“The extreme danger of the patient was manifest, and immediate and energetic means were employed to rouse him. Ammonia was held to the nostrils, and rubbed in large quantity over the surface of the chest and abdomen. It was also applied to the most delicate parts of the skin, e. g., the lips and the extremity of the penis, with a view to excite irritation. Mustard was used; the head was inclined over the bed; and, finally, an attempt was made to restore respiration by means of alternate pressure on the abdomen and chest. After two or three minutes, respiration reappeared, and even acquired a certain fulness, but the pulse nowhere returned. Frictions were continued. Respiration became again slower, and at length ceased. Artificial inflation was practised, at first through the mouth, and afterwards through the larynx, by passing a tube through the glottis, as it was perceived that air had passed from the mouth into the stomach. The precordial, epigastric, and laryngeal regions were energetically cauterised with a hot iron. The pulse did not return. For the space of half an hour every effort was made to resuscitate the patient; but in vain.
“The autopsy could not be made until seventy-two hours after death. The temperature being low, the body showed no signs of decomposition; there was still rigidity of the limbs. The features were not altered. The examination of all the organs was made with care.
“The stomach contained about one ounce and a half of a thick fluid, of the colour of the lees of wine, in no respect resembling an alimentary fluid. The organ was distended with gas, as was also the rest of the alimentary canal, which was otherwise sound. The liver and spleen were somewhat congested.
“The heart, which was normal in volume, was flaccid and empty, contained neither blood nor air. The ventricular parietes were moistened by a fine, very red foam, as if from the presence of a little blood, which had been, as it were, whipped by the fleshy columns of the heart. The venæ cavæ and the portal veins were distended by black fluid blood in great quantity. On the Eustachian valve there was a fibrinous clot, moderately firm, and weighing from sixty to seventy grains. It was the only clot met with in the cavities of the heart and great vessels. These cavities, which were carefully opened, did not contain any appreciable quantity of air.
“The lungs retracted on opening the chest. They presented both in their surface and in their substance a very black colour; otherwise their tissue was healthy. The larynx and trachea presented no lesion. The brain was normal. The sinuses of the dura mater contained a considerable quantity of black uncoagulated blood.”[[79]]
In this case every precaution appears to have been taken, except that which is the most essential, of regulating the amount of vapour in the respired air. Arrangement was made that there should be amply sufficient air for the purpose of respiration; the patient was carefully watched by three persons at least, one of whom was constantly attending to the pulse, but with no other result than to be able to announce the exact moment when it suddenly stopped. The arrest of the action of the heart in this case took place at a time when the patient was not yet rendered insensible by the chloroform, although he had been inhaling it for five minutes. We must conclude that during these five minutes the vapour he inhaled was largely diluted with air, and that he then inhaled vapour in a much less diluted form. It is not improbable that he took a deep inspiration of strong vapour, just at the moment when he struggled violently, and within a quarter of a minute of the time when his pulse suddenly ceased.
The breathing continued a little time after the heart ceased to beat, and it is therefore very probable that, if this organ had not been irrecoverably paralysed, the natural breathing would have restored its action after a short pause, that would have attracted but a momentary attention. As the spontaneous breathing of the patient did not restore the heart’s action, there is no ground for surprise that the measures adopted did not succeed.
Case 10 was that of a labourer, named Samuel Bennett. It occurred on February 20th, 1849, at a dispensary in Westminster. The patient inhaled chloroform for amputation of one of the toes. Half an ounce of chloroform was “sprinkled on a handkerchief, and held over the mouth and nose.... This quantity of the agent failed, however, to produce anæsthesia, having caused only the ordinary excitement and struggling.” After a delay of two hours, more chloroform was procured, and half an ounce was again applied on a handkerchief, “care being taken to allow the entrance of air at short intervals.” Insensibility was induced, and the toe was amputated; the chloroform being applied, as I was told, during part of the time of the operation. At the close of the operation, no blood escaped when the pressure was removed from the arteries; the patient was in fact dying, and in a short time expired. “A few inspiations were noticed after the pulse had ceased at the wrist.”[[80]]
The lungs were of a dark venous hue throughout, a large quantity of blood escaping from them when cut into. Mucous membrane of trachea and bronchi congested. Heart rather large but flabby; auricles empty; each ventricle contained about an ounce of semi-fluid blood (the lungs had been inflated). Head: sinuses and veins contained blood, but not to any remarkable amount. But few bloody points occurred in cutting into the cerebral mass. Kidneys congested.
The failure of the first attempt to cause insensibility in this case, when so large a quantity of chloroform was used, illustrates very forcibly the uncertainty and irregularity of the way in which it was administered. On the first occasion only excitement and struggling were produced, and on the next the patient died suddenly.
Case 11 occurred on August 23rd, 1849, at Langres, France. The subject of it, Madame Labrune, was reported to be a healthy married woman. She inhaled chloroform with the intention of having a tooth extracted. “Complete insensibility was not produced at the first trial: more chloroform was placed on the handkerchief, and she drew a full inspiration. Her countenance immediately became pallid; her features were visibly altered; there was dilatation of the pupils, with a convulsive rolling of the eyes; and no pulse could be felt. Every attempt was made to restore life, but without success. She died as if struck by lightning.”[[81]] The instantaneous arrest of the circulation, on a full inspiration being taken, immediately after more chloroform had been placed on the handkerchief, is particularly worthy of notice. The heart was paralysed, in this instance, as quickly as in experiment No. 25, above related.
No inspection of the body is reported in this case.
Case 12 is the first which occurred in any of the hospitals in this metropolis. The following is the account of it.
“John Shorter, aged forty-eight, a porter, known to Mr. Solly for some time as a very active messenger, habits intemperate, but apparently in perfect health, was admitted into George’s ward, under Mr. Solly, on the 9th October, 1849, suffering from onychia of the left great toe, which had existed some time. It was determined to remove the nail, the man having decided before entering the hospital on taking chloroform.
“On Wednesday, October 10th, at a quarter to two P.M., he began to inhale the chloroform with one drachm in the inhaler. It had no visible effect for about two minutes; it then excited him, and the instrument was removed from the mouth, and about ten drops more were added; he then almost immediately became insensible; the chloroform was taken away, and the nail removed. He continued insensible; and, his face becoming dark, the pulse small, quick, but regular, respiration laborious, his neckerchief was removed, and the chest exposed to fresh air from a window near to the bed; cold water was dashed in his face, the chest rubbed, and ammonia applied to the nose. After struggling for about a minute, he became still, the skin cold, pulse scarcely perceptible, and soon ceased to be felt at the wrist; respiration became slow and at intervals, but continued a few seconds after the cessation of the pulse. Immediately on the appearance of these symptoms, artificial respiration was commenced by depressing the ribs with the hands and then allowing them to rise again until the proper apparatus was brought, when respiration was kept up by means of the trachea tube and bellows, and oxygen gas introduced into the lungs by the same means. Galvanism was also applied through the heart and diaphragm, but all signs of life ceased about six or seven minutes after the commencement of inhalation. These means were persisted in until a quarter past three, but to no purpose. On removing the inhaler, the sponge, which only contains one drachm, fell upon the floor, and the chloroform splashed about,—thus showing that a considerable part of the chloroform remained unused; so that the patient could not have inhaled more than a drachm. Every endeavour was made to procure a post-mortem examination, but in vain.”[[82]]
The above account is published in the Medical Gazette as communicated by Mr. Solly, but it is clearly not written by him, and it presents a very confused narrative of what occurred. If we are to understand the events in the sequence in which they are related, we must conclude that the patient became insensible and had the operation performed, that he then exhibited alarming symptoms for which cold water was dashed in his face and other measures were employed, and yet that after this he struggled for about a minute. This would be a state of things inconsistent, in my opinion, with death from chloroform; but possibly the proper sequence is not observed in detailing what occurred. There is some obscurity also about the amount of chloroform used in connection with what remained on removing the inhaler. If the sponge was adapted to hold a drachm in the proper manner, the chloroform could not splash about on its falling, unless there was a good deal more than a drachm in it. But whatever was the quantity of chloroform remaining in the sponge, as it was in a condition to splash about, it is difficult to perceive what prevented the liquid chloroform from dropping into the patient’s throat, as he lay on his back in bed. Chloroform is as pungent as the essential oils. I have been informed of a case in which a patient was nearly suffocated by one drop falling into the throat; and the narrative of what occurred to Mr. Solly’s patient is not at all inconsistent with death from spasm of the glottis arising from this cause. If, however, the patient died from the vapour of chloroform, we must conclude that he inhaled it at one moment not sufficiently diluted with air.
The chloroform in this case was administered by a non-medical person—a sort of surgery-man. After this accident, however, the chloroform in St. Thomas’s Hospital was always entrusted to some one belonging to the profession.
Case 13 occurred at Shrewsbury, to a Mrs. Jones, a patient of Mr. Clement, surgeon, who had partly performed the operation of excision of the eyeball, when his patient suddenly died. Mr. Clement has, I believe, not published any account of the case, but the evidence which he gave at the inquest was reported in various local newspapers, and copied into the medical journals. The death was very characteristic of the effects of chloroform vapour not sufficiently diluted. Mr. Clement is reported to have said: “He gave her but a small dose to commence with, imbibed from a sponge, and then commenced the operation. Finding that did not make her insensible, about a drachm more was poured on the sponge, which she inhaled again for a few seconds. He then went on with the operation, and shortly afterwards heard a peculiar sound, which he could not describe, and she died in a moment; all the attempts to rouse her proved ineffectual. She spoke in Welsh before she died, but so quickly that he did not know what she said; he had no doubt that she died from the effects of the chloroform.”[[83]]
Case 14 occurred at Berlin. The subject of it was a young lady twenty years of age, of good health, well made, and of a good constitution. The chloroform was inhaled for the extraction of a tooth. It was administered on a sponge, covered with a napkin. The dentist who administered it was not a medical man. He made five unsuccessful attempts to extract the tooth under chloroform. Three of these attempts were at nine in the morning, and two about noon, just before the accident. His patient suddenly died almost at the commencement of the last attempt to administer chloroform, stretching herself out, and frothing at the mouth at the moment of death; the countenance at the same time becoming livid.
An examination of the body took place fifty hours after death, when putrefaction had set in.
“The lungs presented nothing morbid; the bronchi contained a little bloody froth. The blood was of the colour and consistence of cherry juice. The heart was soft, flabby and collapsed. Its coronary vessels and cavities were empty, and presented the bluish-red discoloration of decomposition.”[[84]] The other organs were healthy.
Case 15 occurred in the public hospital of Kingston, Jamaica, on January 29, 1850. The name of the patient was William Bryan, his age is not stated, nor the nature of the operation he was about to undergo. He had previously, however, undergone the operation of amputation of the penis, on account of cancer of that organ, but it was performed without chloroform. Mr. Maygarth, the surgeon who administered the chloroform, stated as follows: “I had about a drachm poured on the sponge, and applied it over his mouth and nostrils, but at first not in close contact—at no period was the atmospheric air totally excluded. He bore it badly, and I was frequently obliged to withdraw it, to facilitate his breathing. The stage of excitement which is usual came on, and he struggled and kept away the sponge for some seconds; it was again reapplied, when, after a few more seconds, observing that he made one stertorous inspiration, I removed it altogether. He ceased to breathe; but after some seconds had elapsed, made another inspiration, and this occurred several times, until at length respiration ceased entirely.” The measures which were employed were of the usual kind, but were of no avail.
The brain and its membranes were found to be congested. The lungs were congested, especially posteriorly. The right side of the heart contained dark fluid blood, and the inner surface of its left cavities, and of the aorta, were stained with blood. There was some disease of the aortic valves, and the heart had undergone some amount of fatty degeneration.[[85]]
Case 16. In February 1850, a death from chloroform occurred on board ship at the Mauritius. A report of the case was sent to the Board of Ordnance, and also to the Admiralty. The secretary of Sir William Burnett first informed me of the case, and a day or two afterwards I had an opportunity, through the kindness of the late Marquis of Anglesey, of reading the report which was sent to him as Master of the Ordnance, and I made a note of the chief particulars as soon as I got home. As the report was a very able one, it is to be regretted it has not been published. The accident occurred to an artilleryman, aged 24, who required to have the last phalanx of the middle finger removed. In other respects, he was considered to be in good health. Two scruples of chloroform were first poured on the handkerchief with which it was administered, and then one scruple more. It was observed that the face turned pale, and the pulse and breathing ceased, soon after the chloroform was discontinued. The measures which were employed to restore him were of no service. The lungs after death were found to be emphysematous; and, upon inquiry, it was ascertained that he had been short of breath on exertion. The right cavities of the heart were filled with fluid blood. The sinuses of the dura mater contained less blood than usual, and the brain was pale. The medical man reporting the case considered that the emphysema was the cause of death, by interfering with expiration, and thus detaining the vapour; and it must be admitted that, if the vapour were not sufficiently diluted with air, the emphysema might increase the danger. I have, however, administered chloroform in several cases in which emphysema existed to an extreme degree, without any ill effects; consequently, when the vapour is properly diluted with air, this affection appears to be no source of danger.
Case 17 was that of a patient of Professor Carl Santesson, in the Seraphim Hospital at Stockholm. I was indebted to Mr. Paget for my first information about this case, and to Dr. W. D. Moore, of Dublin, for some further particulars respecting it.
The patient, a man thirty years of age, was affected with hydrocele, and there was some suspicion of disease of the testicle. It was consequently intended to operate on the hydrocele by incision, in order that the testicle, if diseased, might be removed. The chloroform was administered in the same way that Professor Santesson had seen it exhibited by Dr. Simpson, except that it was poured on a little cotton, which was placed at the small end of the cone, into which the folded towel he made use of was rolled. About a drachm and a half was first poured on the cotton, and the patient was told to inhale in long and deep inspirations. This quantity being nearly evaporated in two or three minutes, a drachm more was added. After a few inspirations rigidity and struggling came on: these subsided, but in a little time returned more strongly than before, and the towel was removed from the face until the struggling ceased. The patient, however, not being sufficiently insensible to undergo the operation with the necessary quietness, the towel was reapplied, when, after a few inspirations, the pulse suddenly ceased. The face and the whole surface of the body turned pale, the eyes rolled upwards and inwards, and the breathing became very slow, but full and deep, the intervals between the inspirations becoming longer, until the respiration ceased altogether. The patient died before the operation was begun, and within five minutes from the commencement of inhalation. During the application of various means of resuscitation, including the dropping of cold water guttatim on the epigastrium, the breathing returned, and continued for the space of three or four minutes; but the pulse and sounds of the heart did not return.
At the examination, thirty-two hours after death, the dura mater was found to be congested, and there was considerable serous effusion between the membranes of the brain. There were also some bony deposits under the dura mater, and some adhesions of the arachnoid, indicating long standing disease of the membranes.
The heart was of normal size, and flaccid; the vessels on its surface strongly distended with blood. The left ventricle was empty; the left auricle, on the contrary, and the entire of the right side of the heart, with the great veins, were filled with thin uncoagulated blood. In the right ventricle only was a little loose coagulum found. The lungs, posteriorly, were highly congested, exhibiting here and there infiltrations of blood from the size of a pea to that of a small hazel-nut. The pulmonary tissue was otherwise sound; giving, however, when cut into, the odour of chloroform, but more feebly than the brain did. The mucous membrane of the larynx and bronchial tubes were slightly reddened from sanguineous congestion. The blood was everywhere of the same thin juice-like nature.[[86]]
Case 18. I am indebted for my information respecting this case to Dr. James Adams, of Glasgow, who was good enough to send me a copy of the notes respecting it, from the case book of his colleague, Mr. Lyon, in whose practice, in the Glasgow Infirmary, the case occurred, in March 1850. The patient was a boy seven or eight years old, from the Highlands, whose health was considerably impaired by years of suffering from calculus. Mr. Lyon says, “being laid in bed, I placed a piece of lint, moistened with chloroform, near to his face, when, in a few minutes, he ceased crying. I now told my clerk to take charge of the chloroform, and introduced the sound. I thought I detected a calculus, but could not hear the click distinctly, in consequence of the patient moaning. One of the bystanders held his hand between my ears and the patient’s face, when the click was at once heard. I withdrew the instrument, and was horror-struck with the livid countenance and vacant eye of the patient; the cardiac and radial pulses were gone, and, making one deep gasp, he was to all appearance dead.” Artificial respiration and other measures were employed without effect. “The external jugulars being remarkably turgid, and the face still very livid, the right jugular was opened, when several ounces of dark blood flowed rapidly.” This measure, and galvanism, which was applied afterwards, were of no avail.
Case 19. The subject of this case was Alexander Scott, aged thirty-four, a police constable, who died in Guy’s Hospital in June 1850, whilst undergoing an operation for the removal of a portion of the right hand. Mr. Cock, the operator, said that he was certain there was no disease about the patient. He described the accident as follows:—“The ordinary machine was used, and, as it had not the effect, witness directed that a napkin should be folded into the shape of a cone, which was applied with chloroform. The occupation of removing a portion of the bone occupied one minute and a half, but before it was completed, the blood which was gushing out, suddenly stopped, when witness directed Mr. Lacy to feel the pulse of deceased, and they found that deceased had expired.”[[87]]
The sudden stopping of the hæmorrhage shews that, in this case, as in the others, the action of the heart was suddenly arrested. The first attempt to cause insensibility failed in this as in some other cases.
Mr. Cock tried to dissuade his patient from having chloroform, severe as the operation would have been without it. In Guy’s Hospital and St. Thomas’s the medical officers had a strong objection to narcotism by inhalation for the first two or three years after the practice was introduced, and chloroform was used much less generally in these institutions than in any other of the hospitals of London; yet it was precisely in these two hospitals that two deaths from chloroform occurred, before any such accident had happened in any other hospital in this metropolis. This circumstance is worthy of the consideration of those who propose to limit the accidents from chloroform by restricting its use to a few great operations.
In this case the lungs were reported to be extremely congested. Heart flabby, not particularly distended; about two ounces of fluid blood on the right side; not more than half an ounce on the left. Head.—Much congestion of the dura mater; the grey matter of the brain was dark and congested; fluid was found in the subarachnoid space; and a considerable quantity of it in both ventricles. Kidneys congested.[[88]]
Case 20 occurred on September 20th, 1850, at the Cavan Infirmary, Ireland. The case occurred in the practice of Dr. Roe, and I am indebted to Dr. Robert Adams, of Dublin, for a manuscript account of it. The name of the patient was James Jones, and his age twenty-four years. Chloroform was exhibited with the intention of performing amputation below the knee, on account of scrofulous disease of the ankle, with ulceration of the cartilages. The patient was reduced to a state of great debility by the disease, and was suffering from hectic fever, but had no cough. The following is Dr. Roe’s account of the accident:—
“When placed on the operating table the heart’s action was very quick and weak, but he did not appear more faint or pale than usual. I then saw Mr. Nalty, the apothecary, measure one drachm of the chloroform in the small minim glass measure, and pour it upon a little folded lint, which was placed in an oval hollow sponge, held in the hand with a small towel. Recollecting I had used this chloroform in another case, and finding some delay in producing the anæsthetic effects, I directed Mr. Nalty to add thirty drops more to that already put on the lint. I then applied the sponge to the patient’s nose, directing him to keep his mouth shut, and gave the towel into the care of Dr. Halpin, who was on the opposite side of the table, while I went to prepare myself for the operation. Mr. Bird had scarcely screwed up the tourniquette, which had been previously placed on the thigh, while I was examining the state of the circulation in the tibial arteries, and which could not have occupied one minute,—certainly the patient could not have taken fifteen inspirations,—when Dr. Halpin told me the anæsthetic effects were produced. This struck me as being unusually quick and sudden, and on removing the towel from the face, we saw a slight convulsive action of the left eyelid (the eyelids were partially open), and a small quantity of frothy saliva at the mouth. I felt rather uneasy, but not much alarmed, as Dr. Halpin said he had often seen such symptoms from the effects of chloroform, although I had not met with them. On a more minute examination of the heart, the eyes, muscles of the limbs, &c. we found him dead.”
Energetic means were used with a view to restore the patient, but without effect. No inspection of the body took place.
Case 21. The next case of recorded death from chloroform occurred in the Stepney Workhouse. The patient, named John Holden, age not stated, was about to undergo an operation on the penis. It was stated at the inquest that half a drachm of chloroform was administered without effect, and then half a drachm more was applied, when the patient suddenly expired. This death occurred in April 1851.
Case 22 is important, as having given rise to a prosecution. The medical man, an officier de santé, named Kobelt, was accused of homicide, by imprudence, want of precautions, &c. The chloroform was administered on a handkerchief, and the accident occurred as suddenly as any of the others. The husband of the patient stated that the whole process did not last a minute. “I observed attentively,” he said, “during this time, and the character that her countenance took all at once made me apprehensive. I spoke of it to the operator, who tranquillized me, and continued to extract the teeth. After the third tooth, however, he partook of my apprehension, suspended the operation, and proceeded to adopt measures indicated by the circumstances.” Professor Sédillot, who had to pronounce an opinion on the case, after hearing all the evidence, said, “I do not think that M. Kobelt is guilty of imprudence or of rashness, because that officier de santé has followed a practice very habitually employed, and even recommended, by eminent practitioners, whose example and authority were sufficient to inspire him with security, and shade him from reproach.” The accused practitioner was acquitted. The above remark of Sédillot applied to the plan of causing insensibility very rapidly, as first recommended by Dr. Simpson; and he added some observations, to the effect that, when used in a different manner, chloroform is free from danger.
The above case occurred at Strasbourg, on June 10th, 1851. The name of the patient was Madame Simon, and her age thirty-six. After death the lungs were found to be somewhat congested, and emphysematous. Heart flaccid, of middle size; right cavities filled with liquid dark-coloured blood, mixed with some fibrinous clots. The left cavities contained similar blood in much smaller quantity.[[89]]
Case 23 occurred on July 8th, 1851, at the Seaman’s Hospital, Greenwich. The patient was a light-coloured mulatto, aged forty-five, native of New York. He died during the operation of removing the left testicle, which was disorganized by suppuration. “The chest had been carefully examined a few days previously, both by percussion and auscultation. No physical signs of disease were detected. His pulse was regular and feeble, about seventy. He was rather nervous, and fearful of the operation. No arcus senilis. After taking a glass of wine he commenced the inhalation, twenty minims of chloroform having been poured on a linen cloth. At the expiration of a few minutes, this had been dissipated, producing only very trifling excitement; a second dose, of the same quantity, was then administered in the same way; the man began to sing and shout, his expressions relating to the firing of guns. The second quantity having been exhausted, and the effects of the chloroform becoming more apparent, but sensibility being still perfect, and even intelligence almost unaffected, a third quantity, of ten minims, was poured out, and, afterwards, twenty minims more. Having passed through the usual convulsive stage, and insensibility being established, the further administration of chloroform was desisted from at the end of about seven minutes, though this time is merely guessed at; it might have been more, but was certainly not less. At this time the respiration was unembarrassed, and the pulse regular, and about seventy, with as much volume as before the inhalation. The lips were florid; in fact, the chloroform appeared to have acted in the most benign way. Mr. Busk commenced the operation by an incision through the scrotum, which divided a small arterial branch, and some enlarged veins, from which the blood flowed pretty freely. The flow, however, almost instantaneously ceased, and Dr. Rooke, who kept his finger on the man’s pulse, found that cease at the same moment. Respiration appeared to cease almost instantaneously with the heart’s action. Regular respiration at least did; for, while we were looking at the man’s face, he fetched one or two sigh-like inspirations. The ribs and abdomen were compressed, so as to induce inspiration and expiration; the lungs were inflated by blowing through the nostrils, the larynx being compressed against the spine, and, for three or four minutes, upon our efforts being suspended, the man occasionally took an inspiration; on one occasion three or four in succession, so as to make us flatter ourselves that he would come round.... It is worthy of remark that, for a long time after spontaneous respiration had ceased, the lips retained a florid colour. The muscles were all relaxed, and the veins on the side of the neck turgid.”[[90]]
At the inspection of the body next day, the vessels of the dura mater, and those on the surface of the brain, were gorged with fluid blood. The lateral sinuses also afforded a flow of dark-coloured blood. There was a considerable quantity of serous fluid in the cavity of the arachnoid and in the spinal sheath. The substance of the brain was very soft. (The weather was warm.) The lungs were of a dark purple colour posteriorly, and much loaded with fluid blood and serum, but were everywhere crepitant and healthy. The external surface of the heart was covered almost entirely with fat; in some parts to a considerable thickness. There were two fibrinous spots on its surface. No fluid in the pericardium. The venæ cavæ were full of fluid blood. On removing the heart, a white fibrous coagulum, about as big as a walnut, was found in the commencement of the pulmonary artery. The heart was uncontracted, and the cavities contained a very small quantity of dark fluid blood. The walls of the right ventricle, and of the left auricle, were thinner than natural. Some portions of the substance of the heart were paler than natural:—“In these paler portions of the muscular substance, the fibres had, for the most part, lost their striated aspect, and had become converted into a fine granular material contained in the sarcolemma. Here and there a minute oil-globule could be observed in the muscular fibrillæ, but nowhere did this amount to fatty degeneration.”
In this case all the precautions appear to have been taken which are possible in making a patient insensible with undiluted chloroform, administered on a handkerchief; and the case, therefore, strongly confirms the proposition that chloroform cannot be administered in this way with perfect safety.
The patient was apparently in the most satisfactory condition at the conclusion of the inhalation, and yet, a few seconds afterwards, the heart suddenly ceased to beat, from the effect, as we must conclude, of that portion of vapour which was in the lungs at the moment when the inhalation was discontinued.
Case 24 occurred in October, 1851, at Chipping Norton, Somerset, to a patient of Mr. Farwell, named Elizabeth Hollis, and aged 37. No one observed the manner in which the breathing and circulation ceased, and, as the patient was in a state of extreme debility, it is not quite certain that the chloroform was the sole cause of death. It was administered to prevent the pain of removing the fæces, which became impacted in the rectum on account of extensive cancerous disease of the uterus and vagina. The surgeon reports that “the time occupied in the inhalation was about eight or nine minutes; quantity inhaled 10½ drachms, half a drachm at a time, allowing her frequently to breathe the atmospheric air. She spoke to me during this period. When I found that her arm fell after being raised, I proceeded to and accomplished the operation. At this time she was not inhaling. I then, as I always do, wetted the face with a sponge, with the view of washing off any remaining chloroform from the nose and lips, when, to my surprise, I found that she had ceased to breathe, and all attempts to restore her were in vain.... When I commenced the operation, the pupil was contracted, and the conjunctiva slightly red. After death, the pupil was very dilated, and the countenance extremely pallid.”[[91]] There was no inspection of the body. This patient had inhaled chloroform on two previous occasions for a similar operation.
Case 25 occurred in St. Bartholomew’s Hospital, on March 17, 1852. Thomas Hayward, aged 23, was suffering from aneurism by anastomosis, occupying the right ear and its neighbourhood. He had inhaled chloroform on the 14th of the previous month, whilst Mr. Lloyd placed ligatures on the temporal artery and some other arteries supplying the tumour; and it was with a view to tie an additional artery, situated between the mastoid process and the ramus of the jaw, that chloroform was again administered.
“The chloroform was some of the same, and the apparatus employed for its administration precisely similar [alluding to the former occasion.] It was administered by one of Mr. Lloyd’s dressers, who well understood, and had great experience in its use. A gentleman of great experience, who had been for years at the hospital, and two years house-surgeon, was watching its effects, and marking the state of the pulse. Other gentlemen were assisting, and also on the look out.
“In from five to ten minutes the usual effect was produced, the patient having previously struggled much. The operation was then commenced; but no sooner had Mr. Lloyd cut the skin, than it was stated that the pulse had suddenly ceased. The chloroform was at once removed; but in a few seconds, the patient had ceased to breathe, and no pulsation could be felt at any of the arteries or the heart.
“Artificial respiration, as well as percussion and compression of the different parts of the body, were immediately employed with energy; and, after continuing the means for a short time, the circulation was observed to be returning, and the act of respiration was several times performed. The state of inanimation, however, speedily returned; but, by the employment of the same means as before, with the use also of galvanism, the circulation and respiration were again restored. Quickly, however, the patient fell into the same state as at first, but was again restored by the same means.
“In a few minutes the state of inanimation again returned, when the external jugular vein, which on the right side was very turgid, was opened, and tracheotomy was performed, and the lungs inflated. The patient was also placed in a warm bath, at the temperature of 104°, artificial respiration being kept up all the time. All, however, was of no avail.”[[92]]
At the examination of the body, the following are amongst the appearances noted. “The venæ innominatæ and vena cava superior were full of blood, and probably would have been distended, but that two or three ounces of blood had flowed into the coffin from the opening made into the external jugular vein. The right auricle and ventricle were distended with blood, and would probably have been more so but for the escape of blood mentioned above. The left auricle and ventricle contained very little blood; the left ventricle was perfectly contracted in the rigor mortis. The heart was of full size. It appeared in every part natural in its texture, and as if it had possessed full power. Its valves also were all healthy; neither could any disease be found in any of the chief bloodvessels within the chest. All the blood, however, was fluid, and it remained without coagulation after its escape from the heart and vessels. It had also a brownish purple hue, much like that which is commonly observed in the spleen: none of it, when thinly spread out, presented the ordinary dark, black, or crimson hue of venous blood. Both lungs were attached by old adhesions about their apices and posterior surfaces, but these were of small extent. Their texture was healthy, but they appeared more than usually collapsed and dry. Their bloodvessels were not over filled.”[[93]]
In this case, every precaution seems to have been taken, except that one which is most essential of all, of regulating the proportion of vapour in the inspired air. It had always been made a great point in St. Bartholomew’s Hospital to attend to the pulse very carefully,[[94]] and on this occasion it was closely examined, but only, as in some other cases, with the result of being able to note the moment when it suddenly ceased.
With regard to the return of the circulation, which is mentioned in the report as having occurred on three occasions, together with the breathing, during the efforts at resuscitation, I understood from inquiries I made of a gentleman present, that this was judged of from the red colour returning to the face and lips, but that the pulse and sounds of the heart were never distinctly perceived after they first ceased. The respiration may cause the colour to return to the face without a true circulation, as I have seen whilst inflating the lungs of still-born children; for if a portion of red blood be mechanically displaced from the lungs by the motion of the chest, it will be propelled by the contractility of the arteries, which continues for some time after death.
Case 26 is related by Dr. Majer, of Ulm.[[95]] It occurred on June 27th, 1852. The patient, Madame W., was 32 years of age, and of good constitution. She was in very good spirits, and was only waiting the operation of having a tooth extracted, before going to dinner. It was stated that only twenty or twenty-five drops of chloroform were put on a sponge, which was surrounded by a handkerchief. After four or five inspirations, the operator inquired if his patient did not feel a singing in the ears. She replied with a trembling and thick voice. At the same time she stretched out her limbs, the face became bluish, the eyes haggard, the head and the arms fell—she was dead. The patient’s husband said, that the time between the inhalation and death was so short that one could scarcely have said Yes or No.
An examination of the body was made twenty-five hours after death. Putrefaction had commenced, and the body was not rigid. The vessels of the membranes of the brain were gorged with blood containing many bubbles of air. The heart was soft and flaccid; the coronary vessels were engorged with blood and air; the cavities of the heart contained air, but little blood. The lungs were congested at the inferior parts.
Case 27 took place at Melbourne, Australia. The name of the patient was Mr. John Atkinson, but his age is not stated. Dr. Thomas, who was about to operate for fistula in ano, said: “Before administering the chloroform, I asked the deceased particularly if he had ever suffered from any serious illness, to which he replied in the negative. I also inquired whether he had been subject to cough or palpitation, and he answered that, some time ago, he had suffered slightly from cough. The pulse was good, and Mr. Barker proceeded in the usual manner to administer the chloroform, which shortly produced convulsive twitchings of the muscles. I then went to the door to request the nurse to send up some person to assist in holding the patient in a proper position for the operation, and I returned to the bed, and poured a little more chloroform on the handkerchief; when it was applied to the face, I heard him splutter at the mouth; the chloroform was instantly discontinued, but the patient suddenly expired. We tried all the means usually resorted to in other cases of suspended animation, but without effect. I had frequently used the same chloroform in other cases. It was not more than a minute after the first application of chloroform that death occurred. About a drachm had been poured on the handkerchief.”
At the examination after death, “there was considerable serous effusion into the pericardium, and the heart itself was larger and more flabby than usual. It was hypertrophied, and there was dilatation of the cavities; the lungs were healthy, and there was a slight appearance of disease about the liver, such as is observed in persons addicted to intemperance.”[[96]]
Case 28. On August 10th, 1852, a Mr. Martin, a cattle dealer died near Melrose, in Scotland, after inhaling chloroform for the application of potassa fusa to some ulcers of the leg. Dr. W. M. Brown, who relates the case, says:—“Before proceeding to apply the caustic I gave him chloroform. He was not easily affected by it, and struggled a good deal. After beginning to apply the caustic I found he was not sufficiently insensible to pain, and gave him a little more chloroform, which had the desired effect. I then proceeded with the application of the caustic, and was just finishing, when I observed a sort of catch in his breathing. I immediately stopped, and, on looking at him, I saw the mouth and eyes open, the breathing irregular, the face pale, the eyes slightly turned upwards, and the pupils dilated.” Dr. Brown tried artificial respiration and other means to resuscitate the patient, but without effect. He says, “in a few minutes the man died.” The pulse is not mentioned, nor the age of the patient.[[97]]
Case 29 took place in the Manchester Royal Infirmary, on December 24th, 1852, during the removal of a malignant tumour of the thigh, by Mr. Jordan. The patient was Henry Hollingsworth, a factory operative. His age is not stated. “The man was very much excited, struggled and talked fast. The chloroform was administered slowly, and every precaution was taken to prevent any danger, and the medical men remarked two or three times how very long it was in taking effect. He at last became insensible, in about seven minutes at least. Mr. Jordan commenced the operation by an incision into the skin covering the tumour. I was assisting the surgeon when Mr. Heath directed my attention to the patient’s face. This was about five minutes after the operation had commenced. I then observed congestion about the face, but there was no stertorous breathing. His pupils appeared almost to have ceased to act. His breathing was becoming exceedingly slow, and he seemed to be sinking fast. I directed the attention of the operator and the other medical men to these symptoms. The operation was then suspended, and means were resorted to for restoring animation, but the pupils had ceased to act, and had become fixed almost immediately. He gave one strong gasp, and then to all appearance was dead. In administering the chloroform, successive doses were given until it took effect. Every dose consisted of a drachm, taken, at intervals, in an inhaler.”[[98]]
The following remark is made respecting the autopsy. “The post-mortem examination shewed that asphyxia, caused by chloroform, produced the death. There was a congestion both of the brain and lungs.” The appearances met with after death from chloroform do not indicate the way in which death has taken place. In animals that are killed by it, the right cavities of the heart are always found filled with blood, whether they die suddenly by its direct action on the heart, or more slowly by its effects on the brain, and the breathing ceases before the circulation. The lungs are seldom much congested in animals, whichever be the mode of dying, and the appearances in the head are not unusual. The state of the pulse is not mentioned in the above account of the case; but congestion about the face was first observed, and then it was noticed that the breathing was getting slow. It is sufficiently probable that the breathing ceased on account of the action of the heart being first arrested; but even if the respiration was embarrassed by the action of the chloroform on the brain, it is pretty certain that that agent also acted directly on the heart; for it cannot be supposed that the means used for restoring animation would have failed, if the heart had been acting properly when the breathing ceased.
Case 30 took place on March 19th, 1853, in University College Hospital, London. The subject of it was an unmarried woman, named Caroline Baker, aged twenty-eight. The chloroform was administered with the intention of applying nitric acid to a sloughing ulceration of the labia and vagina. “The chloroform, supposed in the first instance to be about a drachm, was poured on lint about five inches square, and folded four or five times over. After a short time the patient became restless, talked loudly, and threw about her arms. Soon afterwards a partial relaxation of the limbs took place, and she became insensible and pulseless.”[[99]]
Further symptoms are not given, but it is stated that she sank and died. The breathing is not mentioned, but Mr. Erichsen, who, although not present at the accident to his patient, would be made aware of all that occurred, stated at the inquest, that death was produced by a paralysis of the heart from the influence of the chloroform. Dr. Quain examined the structure of the heart with the microscope, and he “found that organ, particularly on the right side, in a state of fatty degeneration.”
Case 31 was communicated to the Society of Surgery of Paris by M. De Vallet, Surgeon-in-chief to the Hôtel-Dieu, d’Orléans. “A soldier of the line, aged twenty-five, apparently in good health, and of strong frame, consulted M. Vallet for a small tumour situated behind the right labial commissure. Before operating, he proceeded to direct the inhalation of chloroform. The patient, fasting, being placed in the horizontal posture, the chloroform (about one gramme) was poured upon a hollow sponge, and applied to the nose, the mouth being left free. At the expiration of a minute, no effect having been produced, four grammes were poured on the sponge, and at the expiration of four minutes, the patient, without having experienced any irritation of the larynx, without having manifested any resistance, without redness of the countenance, and after only a slight period of agitation, fell into a state of insensibility fit for the operation. Scarcely had the incision been made, necessary to expose the cyst, when the patient became pale, respiration was suspended, and he sank into a state of complete collapse. All the usual remedies were tried, and without avail. M. Vallet opened the trachea, and performed artificial respiration with an elastic tube; then an electric current was sent by needles through the region of the heart. The patient died without any sign of reaction.
“Examination of the body.—The vessels of the brain were empty; the lungs were congested with blood, which in some situations was extravasated; the heart was excessively flaccid; there were some soft clots in the right cavities; the left were empty. The stomach was full of gas; the liver, spleen, and kidneys were gorged with black blood.”[[100]]
Case 32 occurred in the Royal Infirmary of Edinburgh to a man aged forty-three, on whom Dr. Dunsmure was about to operate for stricture of the urethra by perineal section. The chloroform was administered by Dr. Struthers. About an ounce of chloroform was used, and the patient had been put under the influence of this agent on two former occasions, when a similar quantity was employed without ill effect. The following is Dr. Dunsmure’s account of the case:—
“While the patient was inhaling the drug, he struggled considerably, and became a good deal congested in the face and head. He seemed to take a slight convulsion, like an epileptic fit, and such as I have seen on several occasions in people who have led an intemperate life. During the convulsion, the handkerchief containing the chloroform was removed to some distance from the face. In a short time the inhalation took effect, and he began to snore, and although still violent, the chloroform was removed from the face entirely, and the handkerchief placed under the pillow. As soon as the patient became more quiet, he was pulled down on the table, and placed in the proper position for the operation. I then shaved the perineum, and was just going to make my first incision, when one of the assistants said that his pulse was becoming weak. The posterior tibial, Mr. Spence then remarked, was good, but in a second or two after, both gentlemen exclaimed that the pulse was gone. I rushed from my seat to the patient’s head, and found that his breathing had ceased. Those present who had an opportunity of observing the respiration, which I had not, owing to the stool on which I sat being low, positively assert that the breathing did not cease before the pulse. The face was much congested, the jaws were firmly closed, and the pupils were dilated. I immediately forced open the lower jaw by means of the handle of a staff, and with catch forceps pulled out the tongue. Artificial respiration was had recourse to, and in a few minutes he made a long inspiration. This was soon followed by a second, by a third at a longer interval, by a fourth at a still longer period, and then by a fifth, when all attempts at natural breathing ceased. No pulsation could be felt in the radial arteries. The chest was noticed to be much contracted, to have apparently lost its elasticity, and not to expand when the ribs were forcibly compressed during the artificial respiration. I had previously sent for a galvanic apparatus, which was in the flat below, and it arrived almost immediately after the patient had made the fifth inspiration. When the tongue was pulled out, and before the first breath was taken, I was on the point of opening the trachea, but this proceeding was then abandoned; it was now, however, had recourse to, in order to carry on artificial respiration more certainly: the external jugular was also opened, and about a couple of ounces of blood flowed. By the time the tracheotomy tube was inserted, the galvanic apparatus was in working condition, and it was applied on each side of the diaphragm. It acted remarkably well; at each application of the sponges, the muscle descended as if the patient was in life; air passed through the tube in the trachea, and for some time I was in great hopes that the man was to be saved; but the muscle gradually lost its contractility, and although the galvanism was kept up for an hour, it was evident that all our efforts were in vain—that life was extinct. The post-mortem examination was made the following day at one o’clock, rather more than twenty-four hours after the patient’s death, and I give the report of it as drawn up by Dr. Gairdner, the pathologist to the Infirmary:—
“John Mitchell, aged forty-three, died 28th September. A very robust man; height five feet eight inches; diameter (lateral) of base of thorax, ten and a half inches.
“External appearances.—Considerable lividity of face and neck, and more than usual congestion of depending parts. Considerable amount of fat, but more in omentum and around viscera of abdomen than in external parietes.
“Chest.—Right pleura presents a few slight adhesions near the middle; left pleura free. No fluid in either pleural cavity. Pericardium contained about half an ounce of serum, and presented a few opaque patches on its surface. Both sides of heart contained blood, the right side rather more than the left. Blood more than usually fluid. External fat of heart considerable, about three lines on some parts of right ventricle. Muscular tissue of heart generally flabby, and rather pale, but not distinctly disorganized to the naked eye. Valves perfectly healthy. Aorta presented very faint traces of atheroma. A few traces of atrophy of right lung towards its apex and anterior edge, but very limited. In all other respects lungs free from disease, but somewhat congested.
“Spleen soft, but not diffluent.
“Liver congested, but otherwise normal.
“Kidneys congested, but otherwise healthy.
“Brain.—The subarachnoid fluid presents considerable milky opacity, and is of moderate quantity. Moderate congestion of the meninges generally. About half an ounce of fluid in the ventricles. Substance of brain healthy. Arteries at base perfectly free from atheroma. Air passages.—Glottis perfectly patent. Mucous membrane of larynx and trachea slightly congested.
“Microscopic examination shewed the fibres of the heart to be nearly normal, though scarcely so distinctly striated as in some cases. The minute vessels of the brain and pia mater presented at some points a few clustering granules, but to no great extent.”[[101]]
Dr. Dunsmure expressed the opinion that four or five minutes elapsed from the time the chloroform was left off before the pulse failed. But it is pretty certain that he has much over-estimated the time. Indeed, if the shaving of the perineum were likely to occupy even half of this time, the operator would have done it, or had it done, before the chloroform was administered. Dr. Dunsmure makes the following remark in his comments on the case: “In several instances where I have seen chloroform very nearly prove fatal, the respiration became gradually restored after an inspiration had once been made; in this case, however, no such fortunate occurrence took place.” In the other cases to which allusion is here made, the heart has not been paralysed, or at least not completely, but they show that the method of administering chloroform in Edinburgh had been far from satisfactory in its results, although no patient had before that time been actually lost.[[102]]
Case 33 occurred in University College Hospital, London, and the following account of it was given by Dr. Hillier:
“E. R., aged 40, a woman of moderate height, rather thin. The general health has been pretty good; she had not been liable to palpitation or dyspnœa. Had been in the habit of drinking pretty freely. Admitted on October 5th, at 11 p.m. She was suffering from the symptoms of strangulated hernia, which had existed two days and a half. Efforts were made to reduce the hernia, both without and with a warm bath, in which she was for upwards of half an hour without getting very faint. These efforts being unsuccessful, an operation was at once determined on. Her pulse was at this time regular, and of tolerable strength.
“Chloroform was administered in the usual way, on a piece of lint, which was held three or four inches from the patient’s face, and then brought to within an inch and a half of her nose and mouth, leaving space around for the admission of air.
“For three or four minutes nothing unusual presented itself; the pulse and respiration proceeded normally. There was put on the lint, at first, one fluid drachm of chloroform; and, at the end of three or four minutes, forty minims more were added. This was the whole quantity of chloroform employed. Within a minute after the second quantity of chloroform was added, the patient struggled violently both with her arms and legs. During these struggles I was holding her right hand, and was unable to feel the pulse in consequence of her constant motions. The struggling lasted about a minute, and on its ceasing, the patient commenced to breathe with loud, rough stertor. I at once removed the lint from before the face, and felt for the pulse, which I could not find. Immediately cold water was dashed on her face. She breathed with this stertor for two or three short inspirations, and then two or three long ones, and then the breathing ceased. Immediately artificial respiration was resorted to, and within a minute galvanism was applied to the back of her neck and the diaphragm. Under the influence of these agencies, the patient gasped about three times at intervals; after this, no further signs of life were exhibited.
“At the time when the stertor commenced and the pulse failed, the pupils were dilated, and the face of the patient was only slightly altered. The tongue was not retracted, for one of the bystanders at once put his fingers into her mouth to ascertain this.”
At the autopsy made by Dr. Garrod thirteen hours after death, the rigor mortis was well marked; the blood was very fluid in all parts of the body. There was about an ounce of colourless fluid in the pericardium. The heart was quite collapsed and empty, but, as Dr. Garrod observes, this may have been due to the fluidity of the blood. The weight of the heart was seven ounces and three-quarters; valves healthy. Walls of the right ventricle flabby and pale; mean thickness one eighth of an inch. At some parts the muscular substance was in a very thin layer, being much encroached on by fat. In several places there was scarcely any muscular fibre visible. This was chiefly the case near the apex. Examined by the microscope, much fatty degeneration of the muscular fibres of the right ventricle generally was discovered. The walls of the left ventricle were flabby, dry in appearance, pale, and very friable. Both lungs were crepitant throughout, not much engorged. Brain not congested. The intestines above the strangulation were much distended with flatus, and inflamed.[[103]]
Case 34 occurred on October 20th, 1853, a few days after the last. The patient was a young woman named Ann Smith, aged 22 years, under the care of Mr. Paget in St. Bartholomew’s Hospital, who was about to apply the actual cautery to a sore of cancroid nature in the vagina. She was a stout, florid young woman, formerly of dissolute habits, but apparently in perfect health, with the exception of the local ailment. She had been put under the full and prolonged influence of chloroform a fortnight previously for the application of the cautery, without the occurrence of any untoward symptoms whatever. The chloroform was administered by Dr. Black, one of the assistant physicians.
“The usual form of inhaler was employed,—a padded metal cup, fitting over the nose and mouth, and supplied with valves. A drachm, by measure, was first poured on the sponge, but as the administration did not immediately commence, a considerable part of this was no doubt wasted; after a short inhalation, a second drachm was supplied, and subsequently the further quantity of half a drachm. The patient had gone through the usual stages of excitement, etc., and the last dose was scarcely used, as she sank off, almost immediately after its application, into a state of complete insensibility, unattended by any alarming symptoms. About five minutes had been occupied by the inhalation, and probably not more than a drachm and a half of the fluid really inhaled. The apparatus was now removed from the face, and the patient having been drawn into the proper position, Mr. Paget was about to commence the operation, when Dr. Black, who throughout had kept his finger on the pulse, noticed it to have become extremely weak and fluttering. Almost immediately afterwards, the patient’s countenance was observed to be dusky, turgid, and congested, and the respiratory movements began to be performed at long intervals, and by slight catching efforts. No time was lost; cold water was at once dashed on the thighs, face, and breast; and, the failure of the respiration becoming shortly complete, Mr. Paget immediately began artificial insufflation of the lungs, by alternately blowing into the nostrils, and compressing the chest. Just before commencing this process, Mr. Paget had ascertained, by drawing the tongue forwards and examining the glottis with the finger, that the epiglottis was not pressed down.”
Other means were employed, but no further signs of life appeared. It is further recorded that, “immediately after the first alarming symptoms, the pupils were of the medium size, neither contracted nor dilated. All efforts at respiration ceased about two minutes after the first indications of failure; the pulse, however, as a very feeble flutter, was felt occasionally for at least two minutes later.”[[104]]
At the autopsy, performed by Mr. Paget, twenty-two hours after death, “the thorax was first examined, and nothing whatever abnormal could be detected in any of the viscera; the lungs were healthy and crepitant in every part; their posterior lobes were not more congested than is seen in almost every examination; the heart, collapsed, but not contracted, and containing a small quantity of fluid blood in each cavity, was of normal size and proportions, in every respect, and its muscular structure, examined by the microscope, showed no degeneration.... The brain, its sinuses, ventricles, etc., were all carefully examined, and neither in texture nor quantity of blood was anything abnormal detected.”[[105]]
Although the failure of the pulse was the first symptom of danger in this case, it continued to be felt as a very feeble flutter for about four minutes, so that the heart was not so completely paralysed as in most of the fatal cases. It must, however, have been so far paralysed as to be past recovery.
Case 35. Professor Dumreicher related a case of death from chloroform at the meeting of the Vienna Society of Physicians, held on November 16, 1853. The patient was a young man, aged nineteen, in somewhat feeble health, who inhaled chloroform in the recumbent position, in order to have his anchylosed knee-joint forcibly extended. It was inhaled from a vessel resembling a snuff-box, which was held to the nostrils. “The inhalation was continued for fifty seconds, and the patient had spoken a few seconds previously, when Professor D. observed that the pulse had become frequent and undulating. He immediately suspended the administration of the anæsthetic. Trismus occurred; the respirations became irregular; the face turned livid, and he foamed at the mouth.” The measures which were employed included the abstraction of eight ounces of blood from the jugular vein, but they were of no avail. He only once made a feeble attempt at inspiration.[[106]]
Case 36 occurred in the practice of Dr. Wüstefeldt of Neustedt. “A young girl, thirteen years of age, had on the dorsal region a voluminous lipoma, which extended from the last dorsal vertebra to the crest of the ilium.... One drachm of chloroform was employed. As soon as insensibility was manifested, the operation was commenced, but scarcely had the surgeon divided the skin, when the girl, yielding to the laws of gravity, fell suddenly forwards on her chest. Dr. Wüstefeldt, struck by the phenomenon, which he had witnessed before under similar circumstances, immediately desisted from operating, and strove to restore the patient to life; but every effort was useless, and, in the course of a few minutes, it became evident that she was dead.”[[107]]
Further particulars are not given; but as the patient died suddenly, when the surgeon had scarcely divided the skin, it must be admitted that he was, in all probability, correct in attributing the event to the chloroform. The patient usually yields to the laws of gravity when only partially under the influence of chloroform, and it seems surprising that the operation should have been undertaken without placing the patient in the horizontal posture. The proper position of the patient, when a large tumour of the back is to be removed, is to be lying almost flat on the abdomen, the head being a little turned on one side, so that it rests with one ear on the pillow.
Case 37. Jane Morgan, aged fifty-nine, died whilst inhaling chloroform in the Bristol Infirmary, on January 21st, 1854. She was moderately stout, pale, but not otherwise of unhealthy appearance. “The stethoscopic indications were favourable, the beat of the heart was natural, and the air passed freely throughout both lungs; but the chest movements on the right side were not quite so free as on the left.” Chloroform was ordered by Mr. Harrison, the senior surgeon of the Infirmary, with the intention of attempting to reduce a dislocation of the humerus of eight weeks standing. “Having taken no food since her breakfast, she commenced the inhalation of one drachm of chloroform, at 2 P.M., in bed in her ward, under the superintendence of Mr. Hore, the house-surgeon. Nothing unusual occurring in the patient’s general condition during inhalation, a second drachm, in about five minutes from the first, was poured upon the sponge, and the inhalation was continued. Almost immediately after the addition of the second drachm, the chloroform was withdrawn, as the patient’s breathing became stertorous; and immediately afterwards her pulse, which had hitherto continued pretty firm, was suddenly imperceptible, the respiration ceasing at the same time. The pupils were not dilated.” Various measures were promptly resorted to with the hope of restoring the patient; but there were no further signs of life, unless “some convulsive efforts of the respiratory muscles,” under the application of galvanism, be so regarded.
At the examination of the body on the following day, the right pleura was found to be adherent. The lungs were healthy in structure, but gorged with dark fluid blood. There was about an ounce of fluid in the pericardium. There was a small quantity of fluid blood in each of the cavities of the heart. For the length of an inch from their commencement, both coronary arteries were much dilated, and studded with atheromatous and bony deposits. The muscular structure of the heart was examined under the microscope by Dr. William Budd, and a considerable proportion of the fibres were found in a state of incipient fatty degeneration. It was learned, after her death, that she had been subject to occasional attacks of fainting.[[108]]
Case 38. A death from chloroform occurred in the Hôpital St. Antoine, at Paris, in the spring of 1854. The subject of this was a woman aged forty, on whom M. Richard was operating for the removal of a uterine polypus. The surgeon placed the patient in the horizontal posture, and administered the chloroform on a compress of lint. She became insensible in two minutes, having first been excited so that it was necessary to hold her. M. Richard moved the patient to the edge of the bed, gave the compress containing the chloroform into the hands of an assistant, and commenced the operation, which was likely to be of short duration. He had almost completed it, when he was apprised by an assistant, who had been set to feel the pulse, that it had ceased to beat. He sought for it himself, but found that it did not beat. The face was extremely pale; a slow respiration still continued, but soon ceased; and the measures which were used with the hope of restoring the patient were of no avail.[[109]]
At the examination of the body all the organs were found in a healthy state. The right cavities of the heart and the great veins contained a considerable quantity of blood, and the left cavities of the heart a small quantity. The blood was everywhere fluid.[[110]]
Case 39. A patient, named Mrs. Harrup, died at Sheffield from the effects of chloroform administered with the intention of removing a cancerous tumour of the left breast. The age of the patient was forty-five, and she was stated to be in good health, excepting the local affection.
“The chloroform was administered with more than the usual precautions. After the inhalation had gone on without any effect for twenty minutes, it was thought that possibly different chloroform might succeed, and one ounce was accordingly procured from the public dispensary. After the inhalation had been conducted with the fresh chloroform about twenty minutes, the usual effects of the vapour began to manifest themselves. The pulse, which was 136 before any chloroform had been given, and had been very gradually decreasing in frequency while it improved in strength, was now about 104. At this moment muttering—half articulate delirium—came on, but ceased in a few moments, and was immediately followed by conclusive signs of the satisfactory action of the chloroform. Dr. Law now desired Mr. Wright to begin the operation; but before he could do so, Dr. Law, seeing an alarming change in the countenance of the deceased, cried, ‘Stop, Mr. Lewis, how is the pulse?’ I replied, ‘It is gone.’” After stating the means which were used with a view to resuscitate the patient, it is added that the heart had ceased to beat, and that, after a few short and laboured inspirations, life became extinct.
At the examination of the body, the cartilages of the ribs were found to be ossified. The heart and lungs were perfectly healthy, but the lungs were in a congested condition. There was an extravasation of blood in the spinal muscles, and a little blood in the spinal canal, in what part or between what structures is not stated.[[111]]
Case 40 occurred in the Lock Hospital, London, in May 1854. Walter Hollis, a tailor, aged eighteen, had been under treatment for sores within the prepuce, and these having healed, he was about to undergo the operation for congenital phymosis. He had been of dissolute habits, and exhibited a pale cachectic appearance.
“The inhaler used was a simple mouth-piece by which the nostrils are left uncovered. About two drachms of the fluid were poured into the instrument. After about six minutes inhalation, insensibility seemed to be coming on, and at this moment the pulse was ascertained to be of good volume. Nothing whatever had occurred to indicate the impending danger, when, after a few more inhalations, the pulse suddenly failed, became quite imperceptible, and the countenance assumed a pale and leaden hue. The inhalation was immediately stopped, and attempts to resuscitate, by means of striking the chest sharply with a wet towel, applying ammonia to the nostrils, and by artificial respiration, were at once commenced. These were employed for three or four minutes before any signs of life were perceived; but, subsequently, the pulse was again to be felt, and spontaneous respiration was renewed. Artificial respiration was desisted from on the occurrence of these signs of returning life, and for upwards of ten minutes the chest continued to fill regularly, and the pulse beat at a rate of from 40 to 50 in the minute; the countenance of the patient also much improved, and even assumed a slight flush. After the expiration of, perhaps, a little more than ten minutes, however, these indications of returning vitality again disappeared, the pulse and respiratory efforts simultaneously ceased, and the countenance became deathlike. Artificial respiration and the other means were again adopted, but this time without the slightest success.... Post-mortem examination on the next day shewed great venous congestion within the cranium; the lungs were also somewhat congested. The heart was slightly enlarged, and the ventricular parietes were thinned; in the muscular fibres the microscope detected decided fatty degeneration. The blood was universally fluid.”[[112]]
The partial recovery of the patient is a remarkable feature in this case, and it is difficult to explain why he did not recover completely. The number of the pulsations during this partial recovery is mentioned, but not their quality, and I cannot help supposing that the pulse must have been extremely weak, as well as slow, at this period. The ten minutes during which the pulse and breathing returned is mentioned with the qualifying term of “perhaps”, which leads to the supposition that it was not noted by the watch or clock, and under such circumstances of anxiety and suspense, the time might be very much over-rated. The slight fatty degeneration of the heart might probably interfere with the complete recovery of the patient, after this organ had once been paralysed by the chloroform.
Case 41 took place on July 13th, 1854, in the Middlesex Hospital. The patient was a stout, muscular, and florid man, 65 years of age, on whom Mr. De Morgan was about to perform amputation at the upper part of the thigh, on account of a large malignant tumour growing from the inner side of the femur.
“Chloroform was administered by Mr. Sibley, the registrar to the hospital. Snow’s inhaler was employed. The quantity at first placed in the inhaler was rather less than two drachms, and another drachm was added eight minutes afterwards. The patient inhaled the chloroform without difficulty, and went through the usual stages; at the end of about ten minutes violent spasm was induced; this continued about three minutes, and then somewhat abated. The pulse, which had risen to about 120, descended to 70, having a full, steady, and deliberate beat. The pupils, which had been much dilated, became less so. The respiration continued free and deep, but not stertorous. The colour of the face remained good.
“At this moment, which was between thirteen and fourteen minutes from the commencement of the inhalation of the chloroform, the pulse gave a few rapid and irregular beats, and then ceased. Respiration, which, as has been stated, had been going on freely, ceased simultaneously. The face became suddenly pallid and deathlike. The inhaler was removed instantaneously, and cold water dashed on the face. Mr. Sibley immediately commenced to carry on artificial respiration, by applying his mouth to that of the patient, and inflating the lungs. The period that elapsed between the sudden cessation of the pulse and the inflation of the lungs was only a few seconds. After a few inflations, there appeared to be a slight effort at inspiration, but this was the only sign of life discovered after the syncopal attack. Galvanism was in operation within two minutes after the cessation of the pulse.”
“An examination of the body was made by Dr. Corfe forty-eight hours after death. In the head nothing particular was discovered; the brain was firm, and rather more vascular than natural; the blood in the sinus was partly coagulated; the heart was rather larger than natural, and was extremely loaded with fat, especially on the right side, where fat formed three-fourths of the thickness of the wall of the ventricle; the muscular tissue was extremely pale and soft, and exhibited both to the naked eye, and the eye assisted by the microscope, an extreme degree of fatty degeneration; the blood in the cavities of the heart was firmly coagulated; on both sides it was almost purely fibrinous; the clot on the right side was larger than on the left; a fibrinous clot extended down the aorta.”[[113]]
I do not know how the bibulous paper was arranged in the inhaler in this instance, nor whether the inhaler was used with a view to regulating the amount of vapour in the inspired air. The proportion of vapour must have been small during the first ten minutes, as the patient became so slowly insensible; and judging from the result, we must conclude that the proportion was large just before the accident. The firm coagulation of the blood and separation of the fibrin were probably owing to the galvanism which was so promptly applied. I found the fibrin separated from the colouring matter of the blood in the cavities of the heart of a cat, in which shocks of electro-magnetism had been sent through the chest just after it had been killed with chloroform.
Case 42. A man died whilst inhaling chloroform in University College Hospital on October 11th, 1854. The patient was a shoemaker named George Sands, aged 39, and of rather bloated aspect. He inhaled chloroform whilst Mr. Erichsen was endeavouring to introduce a catheter, and had the intention of puncturing the bladder if not successful. The patient was made insensible, and the chloroform was left off, but was reapplied on account of the patient making some expression of pain. “Probably about two minutes of the second inhalation had elapsed, when the man became profoundly insensible, and began to snore with a peculiar and very profound stertor. His face at this time was suffused and flushed, and the inspirations were drawn at rather prolonged intervals. Mr. Erichsen’s attention was at once excited by these symptoms, and, desisting from the use of the catheter, he immediately commenced dashing the patient’s face and chest with water. The chloroform had, of course, been removed. In the course of about a minute, the noise with the breathing gradually lessened, and it became apparent that the respiration was ceasing altogether. Mr. Erichsen now put his finger into the patient’s pharynx, and dragged forwards the root of the tongue; at the same time attempting artificial inflation of the lungs, by applying his own mouth to that of the man. The latter plan did not appear to succeed well, and was almost immediately substituted by the more usual mode of artificial respiration, by compression of the chest, which was kept up most vigorously. The man’s pulse had been felt by the administrator [Mr. Carnell] to be still beating some little time after the commencement of the alarming symptoms and the cessation of respiration. Artificial respiration had been employed for about four minutes, when the man, whose countenance had meanwhile retained its colour and an expression of yet remaining life, began to breathe again. A very short intermission of artificial assistance having been made, he drew spontaneously three or four inspirations; but, as each successive one was more feeble, the artificial aid was at once recommenced. About five minutes from the commencement, the galvanic apparatus was got in readiness and applied. It produced, however, no benefit; and from this time the patient lost colour in the face, and was evidently dead.... The form of inhaler which had been employed was the one in ordinary use at this hospital, viz. a folded piece of lint. The administrator’s hands and the patient’s face had been covered during the inhalation by a towel.”[[114]]
At the examination of the body seventy hours after death, extensive fatty degeneration of the heart was met with. The cavities of the heart were empty, owing, no doubt, to the artificial respiration.[[115]]
The above case differs to a certain extent from those previously quoted, inasmuch as the first symptoms of danger were those of profound coma, and of threatened death by apnœa, as a consequence of the action of the chloroform on the medulla oblongata and nerves of respiration. In addition to this cause of danger, however, the chloroform present in the lungs at the moment when the inhalation was discontinued must have acted directly on the heart, or the prompt assistance of so able an authority on asphyxia as Mr. Erichsen, the moment the breathing was suspended, would surely have restored the patient. The mode of death, although not exactly the same as that in Experiment 24 (page 110), differs from that in the previous experiment, where the heart’s action was good and distinct after the breathing ceased; it resembles the mode of dying in many animals that I have killed with chloroform; being, in fact, a combination of death by apnœa and cardiac syncope, which generally occurs when the quantity of vapour in the respired air is intermediate between that in Experiments 23 and 24, or somewhere between 5 and 10 per cent.
A great peculiarity in the way in which chloroform was administered in the case we are considering was that the head and face of the patient were covered by a towel, under which the lint wetted with chloroform was held. The countenance and state of respiration could not be observed in this mode of giving the chloroform; the person administering it had to depend almost entirely on the pulse; and, except for this cause, there is every reason to conclude that the chloroform would have been withdrawn in this instance in time to save the patient. It was not apparently till a peculiar and very loud stertor attracted the attention of the operating surgeon himself, that the inhalation was discontinued, and the face was already suffused.
This plan of administering chloroform with the head and shoulders of the patient covered with a towel, was introduced by Mr. Clover, who was for several years a resident officer of the institution; and it is but right to state that it led to no accident in his hands; in those of his successors it was, however, less successful; three accidents having occurred in a little more than a year and a half. I much regret to find that Mr. Erichsen recommends this method of giving chloroform in the edition of his work on surgery recently published.
Case 43 occurred in Guy’s Hospital, on December 5th, 1854. The patient was a woman whose leg Mr. Birkett was about to amputate on account of malignant ulceration. She gave her age as fifty-six, but appeared ten years older. “In each eye was a fairly marked arcus senilis, but the woman was not known to have suffered any symptoms referable to thoracic disease.... The administration of the anæsthetic was conducted by Mr. Bryant, the inhaler used consisting of a fold of lint, rather larger than an out-spread hand, and protected on its back by a piece of oiled silk to prevent wasteful evaporation.... In the first instance, about a drachm of the fluid was poured upon the lint. The patient inhaled it kindly; and, after about two minutes, another drachm was added. A stage of excitement now followed, during which the limbs required to be held. Insensibility was just fully established, and Mr. Birkett was on the point of commencing the operation, when Mr. Callaway, who was compressing the femoral artery, exclaimed that the pulse had suddenly ceased entirely. The wrist was examined, and the same found to be the case. Almost immediately afterwards, a long-drawn inspiration, attended with a deep sighing noise, was observed. For two or three breaths the cheeks puffed out during expiration; the respiration next fluttered, and then ceased. Mr. Birkett at once put his finger into the patient’s mouth, and drew forward the tongue, artificial respiration being meanwhile commenced by assistants by means of compression of the chest. A few slight inspirations were attempted by the patient subsequent to the commencement of the artificial assistance; but they did not continue, and no sign of vitality was ever afterwards shown.... It must be noted, that the woman had been very pale both before and throughout the exhibition, and that no change in her appearance was perceived when the alarming symptoms occurred, excepting that the superficial veins of the neck and temple became distended with blood. The cessation of the pulse was most sudden. Mr. Callaway stated that it was not preceded by the least premonitory fluttering, the stroke having been good one beat, and entirely wanting the next. This order of symptoms was of course suggestive of death beginning at the heart (cardiac syncope), the cessation of the functions of the nervous system having been markedly subsequent to that of the circulation....
“Autopsy, twenty-four hours after death (conducted by Dr. Wilks). The corpse was much emaciated, and the rigor mortis imperfect. The lungs were much congested with fluid blood, which ran out after incision of their substance. The heart was of normal size, but soft and flabby; its left side was nearly empty, the right being distended with fluid blood. The left ventricle was of good thickness; its muscle of a deep colour, not encroached on by fat, or in the least mottled, the only observable departure from a healthy state being its flabbiness. The right ventricular wall was very thin, the subserous fat having in some parts almost taken the place of the muscular tissue. The layer of the latter, however, although much thinned, had still a good colour, and did not appear to the naked eye as degenerated, an observation which may apply also to the carneæ columnæ. The liver was in an early stage of cirrhosis, and the kidneys were both of them mottled, and contained numerous small cysts in the external part. The brain was rather paler than usual, its convolutions appeared shrunken and atrophied, and there was a quantity of serous fluid in the arachnoid sac and in the ventricles. There was general atheromatous disease of the arterial system, both in the head and other parts of the body. The blood was universally fluid, and of a dark colour.”[[116]]
As far as could be estimated, the time occupied by inhalation was about three minutes in this case.
Case 44 occurred at the Royal Ophthalmic Hospital, on April 10th, 1855, in a man on whom Mr. Bowman was about to perform excision of the left eyeball. The patient, named John Cannon, was forty years old, and was moderately stout, florid, and healthy-looking. He had generally led a temperate life. The disorganisation of the eye was the result of injury.
“The inhaler used was the one devised and recommended by Dr. Snow.... The administration was entrusted to Dr. Playne, of King’s College Hospital. In the commencement of the inhalation, the valve of the mouth-piece was so turned as to admit an abundant supply of air, a point to which Mr. Bowman directed personal attention. During the first four minutes (more or less) nothing unusual occurred. Dr. Playne, who had his finger on the pulse, had noticed that it had rather increased in fulness, and was of good volume. Rather suddenly, however, just as the anæsthetic appeared to be producing its effect, symptoms of excitement occurred. The eyes became fixed and staring, the arms outstretched and rigid, and the face contorted. It was now impracticable to feel the pulse, on account of the tossing about of the arms; but, as is usual in such conditions, the respiration was noticed to be all but, if not quite, suspended by the spasmodic fixture of the chest. The inhaler was at once removed, and the face and chest of the patient dashed with cold water. Almost immediately after, as the respirations had become extremely feeble and sighing, Mr. Bowman commenced practising artificial breathing, by the application of his own mouth to that of the patient. By this means, the chest was made to fill very completely, and the process was kept up almost without intermission for from five to eight minutes. During the first three or four minutes after the alarm began, the patient continued at times to make slight sighing efforts at voluntary inspiration, and the case was not thought, by those looking on, to be by any means hopeless. At length, however, these finally ceased, and from that time it was apparent that the man was dead.... At the first opportunity which occurred for examining it after the spasmodic struggling had commenced, the pulse was found to be extinct, and it remained so ever after, although there were, as stated, feeble efforts at inspiration. The patient’s countenance changed somewhat during the treatment, but was mostly suffused and congested.”
At the examination of the body forty-eight hours after death, “the sinuses, and the veins of the brain generally, were much congested, and there was some œdema of the brain substance. The heart, excepting some slight deposits on the curtains of the mitral valve, was healthy. Its muscular substance was easily lacerable. The right ventricle contained a considerable quantity of fluid blood, the left was nearly empty. There were some pleuritic adhesions, and the lungs generally were congested, being also in some parts full of air. The blood in every organ examined was fluid, and without trace of coagulation.”[[117]]
It does not seem that the inhaler used in this case was employed with the object for which it was contrived—that of regulating the amount of vapour in the inspired air; and I do not know whether the bibulous paper was arranged properly in the interior.
Case 45. On September 8th, 1855, a lady, aged twenty-nine, the wife of a physician, died suddenly whilst inhaling chloroform for the relief of facial neuralgia. I was sent for when the accident happened, and arrived twenty minutes afterwards. I found the deceased lady without any sign of life. The face and lips were very pallid. The husband was performing artificial respiration by mouth to mouth inflation of the lungs, and alternate pressure on the chest, and I assisted him in this for a long time, though with no hope that any thing could be of service. Dr. Barker, of Grosvenor Street, arrived soon after me, and assisted in the same measures. An inhaler was employed in this case consisting of a face-piece, like the one above delineated in this work, and a bent metal tube lined with bibulous paper. Two quantities of ten minims each had been inhaled, with some relief to the pain, and without causing unconsciousness when the inhaler and the chloroform were put away in a closet; but the patient begged to have more chloroform, in order to be completely relieved of the pain, as she had been on a previous day. Ten minims more chloroform, as I was informed, were put into the inhaler, and the patient, being seated on a sofa, began to inhale very eagerly, but had no sooner commenced than she gave a sudden start, as if taken in some kind of fit. Her husband laid her on the floor, but she evinced no further signs of life.
There was no inspection of the body.
The only explanation which the case admits of is that, in her eagerness to get relief, the patient took one or more inspirations of air very highly charged with vapour. The symptoms were those of death by cardiac syncope.
Case 46 occurred in the practice of Dr. Roberts, a surgeon dentist of Edinburgh. The patient was a lady, thirty-six years of age, to whom Dr. Roberts had administered chloroform on four previous occasions within a twelve-month. Dr. Roberts says the chloroform was administered in the usual way, by which he means on a handkerchief. He says: “Mrs. H. had only taken about nine or ten inspirations, obtaining but a partial influence of a quantity short of ʒiss poured out from the bottle, and inhaling it for a space of time certainly less than a minute, when she said, ‘You must not operate until I am quite insensible;’ and again, ‘I am not over yet;’ and immediately, even while speaking, she gave a convulsive start, and with a stertorous inspiration, and with the eyes and mouth open, sunk to the floor.” Dr. Simpson was sent for, and arrived within five minutes. Artificial respiration was resorted to, and after it had been applied for a time, there were a few spontaneous inspirations, and the pulse, it is said, could be perceived at the wrist; but these symptoms of reviving animation disappeared.
At the examination of the body, the right cavities of the heart were found gorged with blood. The walls of the right ventricle were thinner than natural, and affected to a certain extent with fatty degeneration.[[118]]
A paragraph was inserted in some of the Edinburgh newspapers, and forwarded by Dr. Roberts to the Lancet,[[119]] in which it was implied that death in this case was not caused by the chloroform. It is, however, like the preceding case, a well marked instance of the sudden and fatal action of this agent.
Case 47. A sailor, aged thirty, died whilst inhaling chloroform in St. Thomas’ Hospital, in October 1856, preparatory to having some necrosed bone removed from one of his fingers. “He did not appear to be in robust health; still there was no obvious reason against his having the chloroform, which was accordingly administered as follows. One drachm was poured on a sponge folded between two thicknesses of lint, and this held at a little distance from his mouth, while he was sitting in a chair. He appeared to be going off very comfortably, when the chloroform was left off for from half a minute to a minute, and then resumed. He now began to raise his hands and tremble, and kept spitting in the lint, and appeared as if about to vomit. Suddenly he was violently convulsed through his whole frame, as if in an epileptic fit. The chloroform was at once discontinued, and he was laid in a semi-horizontal posture. The convulsion only lasted for a few seconds, and when it had ceased he began to breathe with effort and puffing of the lips, and almost immediately to gasp irregularly. His pulse was almost imperceptible and intermittent. Artificial respiration was at once performed by alternate compression and relaxation of the walls of the chest, the tongue being held out of the mouth by the forceps. Ammonia was applied to the nostrils, and cold water dashed in the face, and in about a minute he rallied so as to breathe without assistance, but in a few seconds he relapsed, and could not be recovered.
“At the post-mortem examination there was found to be fatty degeneration of the heart, liver, and spleen, and the membranes of the brain were thickened. The lining of the ventricles presented a peculiar pitted appearance, apparently from inflammatory deposit. The brain itself was pale.”[[120]]
“It was ascertained after the man’s death that he had been of intemperate habits, and had had an attack of delirium tremens three weeks previously. In the report of this case in the Association Medical Journal, the following is the account of the appearances met with after death. In the autopsy in the present case, which we observed with particular care, the brain was in a state of œdema and bloodlessness, very like the brain in a patient who died from chloroform in the Ophthalmic Hospital. The liver was fatty; but the heart seemed the very model or type of the healthiest kind of heart. All the other organs were also healthy.”[[121]]
Case 48 is related by Mr. Paget as follows. “I am anxious to place before the profession, at the earliest opportunity, a narrative of a case in which chloroform proved fatal in my private practice.
“The patient was a boy, nine years old, of delicate constitution, and of nervous, timid disposition; but with no indication of any organic disease, except that for which the operation was to be performed: namely, a tumour of the scapula; for which it was proposed to remove the greater part of that bone.
“At half-past eight A.M., on February 28th, after the patient had passed a night of sound sleep, the chloroform was first administered in a room adjoining that in which the operation was to be performed. He was alarmed at the thought of being put to sleep, and of what would then be done, and was very averse from taking chloroform, but he was persuaded to inhale it; and, though not without resistance, yet with less than is commonly made by patients of the same age, he was brought under its full influence in about three minutes. He sat in bed during the first few inspirations, and after these, was recumbent. It was observed that two or three deep inhalations were quickly followed by complete insensibility; and the next few inspirations were stertorous. He was at once carried, in the horizontal posture, into the room, and laid on the table, arranged for the operation.
“Three or four minutes passed while we were arranging his position and his dress, and while I was pointing out to those who were to assist me the proposed plan of operation. During this time the influence of the chloroform so far passed off, that he became sensible, displaced his coverings and pillows, said something expressive of discomfort, and vomited a small quantity of frothy fluid. (He had taken no food since the previous night, when he had had a good supper.) A very small quantity more of chloroform was slowly inhaled, and he became again nearly quiet, and was again placed on his side. I was on the point of commencing the operation, but as he again, by movements, indicated some degree of sensibility, and changed his posture, about forty drops more of chloroform were poured on cotton wool, inclosed in a fold of lint,—an inhaler, with the chloroform on sponge, having been previously used. The lint was held, about half an inch from the face, by Mr. Thomas Smith, my usual assistant in operations. The patient inhaled lightly for a few times, then made one long inspiration, and appeared to pass at once into deep sleep. Except that he thus appeared to come suddenly under the full influence of chloroform, no external change was visible; but, a few seconds later, his pulse, which had been carefully watched, and had been to this time normal, suddenly began to beat very quickly; then it ceased for two or three seconds; then beat rapidly several times, with a kind of flickering movement; and then ceased to be perceptible.
“Just before this change of the pulse was observed, the chloroform had been withdrawn. The one deep inspiration was followed by a few stertorous breathings, but after these he breathed naturally, his complexion and features showed no change, he seemed only calmly asleep, and in this state he continued breathing naturally, and with no change in his appearance, but pulseless, for at least a minute. Then his breathing became less frequent, and seemed as if it might soon cease; his face grew pale, and his lips very slightly livid.
“With the help of cold water sprinkled on his chest and face, and cold air blown on his face and throat, he was raised from this state of defective breathing in about two minutes, and again breathed deeply and freely, though slowly, (probably about twelve times in the minute.) He thus breathed for two or three minutes, and during this time the lips, and the pale or slightly livid parts of the face, became pink again, and though no pulse could be felt at the wrists, the heart was heard acting. During this time, also, some wine and brandy were poured into the mouth, and passed down the œsophagus, but without any evident movements of swallowing. His breathing again became gradually infrequent and feeble. Cold air and sprinkling with water, frictions and percussions of the chest, scarcely increased the breathing, and in less than two minutes it ceased. Artificial respiration, by the method of Dr. Marshall Hall, was immediately employed, and many times during the first five minutes of its employment the artificial inspiration obtained, when turning the body over to its side, was followed by a distinct, and sometimes even a full muscular inspiration. But at the end of about five minutes, these signs of life ceased, fæces escaped, and no more indications of life appeared, though the artificial breathing, the friction of the limbs, and other means for resuscitation, were continued for twenty or more minutes.
“I refrain, at present, from all comments on this case. Only, I wish to call particular attention to the fact that good breathing was maintained, and, after a suspension, was renewed, long after the heart had ceased to act with sufficient force to produce a pulse at the wrist. And I would add, that this narration is sanctioned and considered to be exact, by the four gentlemen who were to have assisted in the operation, and to whom I am greatly indebted for their counsel and assistance in the greater difficulty that we had to cope with.”[[122]]
Case 49. This case occurred in the Liverpool Infirmary on April 5, 1857, and is related by Mr. Allan, the resident officer who administered the chloroform. The subject of the case was a labourer, aged 35, on whom Mr. Bickersteth was about to perform amputation of the thigh on account of gangrene following the ligature of the femoral artery. He had inhaled the chloroform six days previously without ill effects, when the femoral artery was tied for popliteal aneurism. On the day of the accident, he was first rendered insensible in the ward by chloroform poured on a piece of lint which was held a short distance from the nose and mouth. Having partially recovered during his removal into the operating theatre, the chloroform was reapplied, and Mr. Allan relates what occurred as follows: “About half a drachm of chloroform was now poured on some lint, which was held to the nostrils, and he then became fully under the influence; respirations good; pulse frequent, feeble. The operation was about to be commenced, and I was pouring about twenty minims more chloroform on the lint, (having pronounced the patient to be in a fit state,) so as to be ready to give him some more as occasion required, but had not applied it, when, turning round, I noticed something peculiar in his general appearance, and, on lifting up the eyelid, found the pupil dilated, and the lid did not close over on the removal of the finger; the eyes were slightly turned up. I at once felt for the temporal artery, but there was no pulsation, and none detected at the left wrist; the respirations had almost ceased. The head was lowered, cold water was dashed on the face, and the abdomen struck with the palm of the hand; the finger thrust into the mouth (there was no action of the heart felt); the legs were elevated, and a wet towel was dabbed over the epigastrium. After one or two blows, the respirations became better, and seemed good, and in about two minutes a pulse was felt at the wrist. This continued between two and three minutes, the respiration being good. His pulse then began to fail, and in about a minute more the respirations were less. The tongue was seized with a pair of forceps, and drawn forwards, and artificial respiration tried, and ammonia held to the nostrils; but he was becoming livid in the face, so the Ready Method was at once adopted, and this produced apparently a few natural respirations. But the pulse had gone, and in about two minutes more there was no breathing save artificial. About the time that the pulse stopped, there was a convulsive movement of the muscles of the leg, and a slight clamminess of the skin succeeded. The Ready Method was continued for half an hour, and galvanism tried, but without avail. From the time he was placed on the table to his death, or the cessation of natural respiration, about ten minutes elapsed.”
The writer adds: “He apparently sank from syncope, or cessation of the heart’s action, for his respiration had been good just before he changed, and it continued for a second or two, though faint, when the pulse had stopped; and after the respiration had been restored, and was very good, the pulse was very feeble, and ceased two minutes before the respiration.”
At the autopsy on the following day, the brain was found to be healthy, tolerably firm, and pale; the lungs were healthy; the right cavities of the heart contained some fluid blood, which afterwards coagulated on exposure, and a small clot. The left cavities also contained some blood. The muscular tissue of the heart had an unhealthy look, and very readily tore, but no oil globules were discovered with the aid of the microscope.[[123]]
Case 50 occurred in King’s College Hospital, August 7th, 1857. The following is the account of the case furnished by Mr. C. Heath, the House-surgeon:—
“The patient [Ann Stoner] was a female, aged seventeen, under Mr. Partridge’s care, with syphilitic warts and mucous tubercles. She was admitted July 8th, and had had chloroform administered twice, in order that the sores might be touched with nitric acid, and, on both occasions, not the slightest ill effect was produced. On Friday evening last, chloroform was again administered for the same purpose; only a drachm was put into the inhaler (Snow’s), and as soon as she became unconscious the inhaler was removed, and the acid applied. I and my assistant (who administered the chloroform), then went to see another patient in the same ward, and then washed our hands, during which time the patient was moving her legs about much as they do when recovering, and in addition she made water over the bed. I gave directions to the nurse to apply a poultice as usual, and left the ward, having been up to the bed first without noticing anything unusual about the patient. In a few minutes the nurse came down for some medicine for another patient, and mentioned that this one was looking very pale: I sent up Mr. Liddon to see her at once; he found her pale and senseless, dashed some water over her, and called me, and I went up immediately. I found her pulseless and cold, and immediately commenced artificial respiration (Marshall Hall), and sent for the galvanic battery; this was brought and applied without effect, and the artificial respiration was continued for twenty-five minutes without the slightest effect being produced.”[[124]]
I was present at the examination of the body on the following day. The mouth was sore and swollen from the effects of the inunction of mercury. There were a few drachms of clear serum in the pericardium. The heart was large for the size of the patient. There was a patch of organised lymph on the pericardium, covering the left ventricle. The right cavities of the heart were full of dark fluid blood, and the left cavities contained a little. The mitral valve was much thickened, but the other valves were healthy. The lungs were healthy, and not much congested. The brain was healthy. The patient had suffered from acute rheumatism before entering the hospital.
It will be observed that the pulse is not mentioned in the above case, until its absence is alluded to, when the patient was already cold, and the breathing is not alluded to throughout the account; indeed, it is not known when the patient died. She was alive after the application of the nitric acid, as she was observed to move her legs, but further than this there is no clear evidence.
It is perhaps an open question whether this patient died at once from the direct effects of the chloroform, or whether she died after partially recovering and going on favourably for a time. The account would, at first view, seem to favour the latter opinion, but it is not corroborated by any other case. Patients have been partially recovered from the effects of an overdose, without being entirely restored, and others have sunk after great operations, attended with hæmorrhage, when the effects of the chloroform had more or less subsided, but there is no instance of a patient going on favourably, and partially recovering from the influence of the vapour, and then dying suddenly without any other known cause. Patients have occasionally become faint whilst recovering from chloroform, more especially if they remain in the sitting posture, but in those cases the right side of the heart is probably insufficiently supplied with blood; whilst, in the case under consideration, the patient was lying, and the right cavities of the heart were found full after death, the serum in the pericardium showing that they had probably been distended when death took place. If Mr. Heath had made any observation which enabled him to say that the patient was really alive, when he went up to the foot of the bed, before leaving the ward, it would decide the question, and show that death did not take place at once from the direct effects of the chloroform, but he only makes the negative remark that he did not notice anything unusual about the patient.
I had an opportunity of examining the particular inhaler employed, and found that it was so arranged that the vapour might be breathed from it in much greater proportion than would be safe, if precautions were not taken to leave the expiratory valve a considerable way open, especially when the high temperature of the weather at the time is taken into account.
The foregoing cases comprise all the instances I have seen recorded in which death appears to have been occasioned by the administration of chloroform, and not by other causes in operation about the same time. A few additional cases have indeed been referred to by different authors where death was probably caused by chloroform, but as I do not find that the details have been published, I cannot make them available in an inquiry respecting the cause and prevention of these accidents.
In June 1852, Dr. Simpson alluded in the following terms to an accident from chloroform which had occurred near Glasgow:—“In this instance, chloroform was given by the practitioner for tooth extraction; but, I am sorry to add, none of the parties present were at the time in a condition to give any satisfactory evidence.”[[125]]
A person, named Breton, a dealer in porcelain, died in Paris, in the early part of 1853, immediately after a few inspirations of chloroform, which was administered with the intention of removing a tumour of the cheek. An action was brought against Dr. Triquet and M. Masson for causing death by imprudence in this case; and at the trial which ensued, various interesting opinions were given, and the accused practitioners were ultimately exonerated.[[126]] I have not, however, met with any record of the symptoms which occurred in the case.
In relating the case of death from chloroform, which occurred in his practice, to the Medical and Chirurgical Society of Edinburgh, Dr. Roberts referred to another death from chloroform in tooth-drawing which took place in the neighbourhood from which his own patient came, just previously to October 1855; but I have not met with any account of the case so alluded to. Dr. Mackenzie of Kelso also alluded in the same Society, in the following year, to a death from chloroform which had occurred at Coldstream, and I do not know whether this was the case to which Dr. Roberts had alluded, or a fresh one.
One of the surgeons to the hospital at St. Louis, who was lately visiting the medical institutions of London, informed me that there had been three deaths from chloroform at his hospital out of between six and seven hundred operations in which it had been administered. I did not learn the particulars of those fatal cases.
There have been several cases in which persons have been found dead after inhaling chloroform when no one else was present, either for toothache or some other affection, but I have not included such cases in the above list, as they throw no light on the way in which death is occasioned. The simple way to avoid such accidents as those just alluded to, is for persons to abstain from inhaling chloroform, when no one is by to watch its effects.
