ALLEGED FATAL CASES OF INHALATION OF CHLOROFORM.
Several deaths have been attributed to chloroform which were due to other causes, or where the cause of death is a subject of great doubt. A gentleman, named Walter Badger, twenty-two years of age, the son of one of the coroners for the county of York, died instantly at Mr. Robinson’s, the dentist’s, in Gower Street, on June 30th, 1848, whilst commencing to inhale chloroform with the intention of having some teeth extracted. The inhaler employed consisted of a face-piece to enclose the mouth and nostrils, and containing a sponge on which the chloroform (ʒiss) was placed. This, according to the evidence of Mr. Robinson and his female servant, who was present in the room, was held not nearer than an inch and a half from the face for less than a minute, and the patient made the remark that the chloroform was not strong enough; Mr. Robinson requested him, as he had done before, to have the operation performed without chloroform, but he again declined; and Mr. Robinson then took away the face-piece and asked his servant to reach the bottle, intending to put more chloroform on the sponge, to replace that which he believed had been lost by evaporation. Just after removing the face-piece, and before any fresh chloroform was poured out, the head and hand of the patient dropped, and he did not show any further sign of life.
I found, on making trial of the kind of inhaler which Mr. Robinson employed, that it is impossible to inhale enough of the vapour to produce any appreciable effect, unless it is applied so as to touch the face. At the distance of an inch no effect is produced, even in five or ten minutes; and therefore I expressed my opinion, soon after this accident, that it was not caused by the chloroform, which properly speaking the patient did not inhale.
A consideration of the symptoms in this case confirms the view that the death was not caused by chloroform. In six of the fatal cases related above, death took place instantaneously, without insensibility or any of the usual effects of chloroform having been produced; but the mode of dying was not the same as in Mr. Robinson’s patient. In Case 4, that of Madlle. Stock, the patient said “I choke”, and tried to push away the handkerchief; then there was embarrassed breathing and foaming at the mouth. In Case 11, that of Madame Labrune, the fatal attack followed immediately on a full inspiration of chloroform, and there was an immediate alteration of the features, and a convulsive rolling of the eyes, amongst other symptoms. In Case 14, the young lady stretched herself out, and frothed at the mouth, at the moment of the fatal attack, and the face became livid. In Case 26, that of Madame W., who died at Ulm, the voice, when answering the question about singing in her ears, was trembling and thick; she stretched out her limbs, and the face became bluish. In Case 45, that of the wife of a medical man, and in 46, that of Dr. Roberts’s patient in Edinburgh, there was a convulsive start at the moment of the sudden death. It thus appears that when the heart is suddenly paralysed by an overdose of chloroform, before the patient is rendered insensible, there are usually some symptoms as if of a violent shock or injury. After complete insensibility is induced, the heart may be suddenly paralysed by chloroform, as is shown by numerous cases, without this spasmodic action; and it would perhaps be premature to deny that a patient might die thus quietly without being first made insensible; and the nature of the death in this particular case must be chiefly decided by the physical fact that the patient could not have inhaled enough chloroform to produce an appreciable effect of any kind, much less to cause sudden death.
At the inspection of the body, the liver was found so much enlarged that it weighed eight pounds, and it encroached very much on the chest. The walls of the left ventricle of the heart were found thinner than natural, and the muscular tissue was interspersed with fatty degeneration. There was blood in the right auricle and in both ventricles. In the ventricles it was partly coagulated. The brain presented nothing abnormal.[[127]]
It is probable that the immediate cause of death in this instance was fear. The patient had been told in the country that it would be unsafe for him to take chloroform, and yet he could not summon resolution to undergo the operation without it. Mr. Robinson unfortunately allowed his patient to remain seated in the operating chair; and it was only when Dr. Waters had been sent for and arrived from a neighbouring street that he was laid on the floor.
I was present on one occasion with Mr. Peter Marshall at the examination of the body of a woman who died suddenly of fright in consequence of a fire in the next house to that in which she lived, and it is worthy of remark that we found exactly the same diseased conditions as those which were found in Mr. Robinson’s patient; viz., great enlargement of the liver, displacing the viscera of the chest, and fatty degeneration of the heart.
A young man, aged twenty-four, died suddenly of syncope, on June 25th, 1848, at the Hospital Beaujon, at Paris, whilst M. Robert was performing amputation at the hip joint, the thigh bone having been broken into splinters by a bullet during the conflict in the streets of Paris. The patient was in a state of great depression, both physical and moral, before the operation; and it is most likely that he sank under the combined effects of the injury and the operation.
Another patient had the neck of the humerus broken by a ball in the same conflict; he was much reduced by hæmorrhage and gangrene of the wound; M. Malgaigne performed disarticulation at the shoulder joint; a fresh inhalation took place to enable him to search for the ball, and the patient sank and died during the last incisions. This patient also most probably died from the effects of the operation added to those of the previous injury and loss of blood.
A woman died in Paris, 1848, after removal of the breast. The operation was finished, and the chloroform had been left off some time, and the patient had become conscious, when on raising her into a sitting posture, in order to apply a bandage, she suddenly expired. Although the chloroform was blamed in this instance, death evidently took place by the ordinary kind of syncope, which arises from the heart not being supplied with blood, and which may be called anæmic syncope, in contradistinction to cardiac syncope, which begins at the heart itself, when properly supplied, or even when distended with blood.
A child, aged twelve years, died in the hospital at Madrid in 1849, during amputation of the leg after violent tetanic rigidity.[[128]] Death was attributed to the chloroform which had been inhaled, but no further particulars are given, and it is not stated whether or not there was any unusual hæmorrhage, or other cause, which would explain the fatal event.
Dr. Aschendorf has attributed the death of a child a year old to chloroform.[[129]] The child had a nævus on the face and neck, which extended from the zygoma to the os hyoides, and from the external auditory meatus to the maxillary fossa. No one had been willing to undertake its removal. Dr. Aschendorf operated on the nævus at three different times, by means of seton threads. These operations were performed under the influence of chloroform. The tumour was reduced one-third part in size by these means, and eleven weeks afterwards Dr. Aschendorf determined to extirpate it. The chloroform was administered as on the former occasions, by placing six drops on some tow in a cup. In about ten minutes, as the child cried a little, three drops more of chloroform were used for inhalation, and in about eight minutes more the operation was concluded. “On raising the child it laid its head on one side, convulsive twitches of the face were observed, with distortion of the eyeballs and dilatation of the pupils. For one moment the arms were stretched out stiff, then again they were relaxed, and fell as supple as the rest of the body. Death quickly followed—only one pulsation of the heart and a single râle with the expiration being perceived.”
There can be no doubt of this being a case of death from hæmorrhage, after the direct effects of the chloroform had subsided. Dr. Aschendorf says the quantity of blood lost was about two tablespoonfuls; but it would be necessarily removed by sponges during the operation, and there would be no means of estimating the quantity. The child was probably in a state of syncope during the latter part of the operation, as it would not remain insensible to the knife for eight minutes from a single application of chloroform.
On September 15th, 1852, a patient died to whom I was administering chloroform whilst Mr. Cæsar Hawkins was performing lithotrity. He was a gentleman from the country, aged seventy-three; he was tall and stout, he had a weak intermitting pulse, and a well marked arcus senilis in each cornea. He had inhaled chloroform five or six times, between May 1850 and May 1851, for the same operation, when under the treatment of another surgeon, and it always acted favourably. In the first week of December 1851, Mr. Hawkins performed the operation of lithotrity twice, when the chloroform was administered by Mr. Geo. D. Pollock. On the second of these occasions he became faint during the operation whilst under the influence of the chloroform, but recovered from the faintness before its conclusion. He again fell into a very alarming state of syncope a few minutes after the conclusion of the operation, but rallied, and vomited the breakfast which he had taken a little time before. I first administered the chloroform to this patient on December 15th, 1851, eleven days after the above occurrence. Mr. Hawkins and I were inclined to think that the alarming syncope on the previous occasion might have been connected with the sickness which occurred. It was my firm belief that the patient had fatty disease of the heart; but I did not see any great objection to the chloroform on that account, as I had frequently given it in similar cases, and always with a favourable result. On this occasion (December 15th) he inhaled the chloroform before breakfast. Its effects were quite satisfactory, and it was not accompanied or followed by any unpleasant symptoms whatever. The operation was repeated four days afterwards, when I again exhibited the chloroform with like favourable results. After this the patient went back to the country relieved from his stone. He came back, however, in the autumn of 1852, with a return of his complaint, and I was again requested by Mr. Hawkins to assist him by giving the chloroform on September 15th.
The patient became insensible, without any excitement or struggling, in the course of three or four minutes, and the operation was commenced. A little more chloroform was administered two or three times during the operation, in order to keep up the insensibility. After a few minutes had elapsed, I observed that the face and lips of the patient became pale. At this time he had not inhaled any chloroform for about two minutes. Immediately afterwards, however, his face became red, and he made straining efforts with the muscles of respiration, as if he were beginning to feel the operation. To prevent his becoming altogether sensible, therefore, I commenced to give him a little more chloroform, with the valve of the inhaler about one-third open, as on the former occasions. He had only taken two or three inspirations, however, when the breathing ceased. He appeared to be merely holding his breath, as sometimes happens during the exhibition of chloroform, and I expected that he would begin to breathe again in about a quarter of a minute. In the meantime, I endeavoured to feel the pulse in the temporal artery, but did not perceive any. Instead of the breathing recommencing at the time I expected, the countenance became suddenly pale, and a little afterwards rather livid. I applied my ear over the region of the heart, but could not hear any sound. After a few seconds, however, the patient took a rather deep inspiration, and immediately after this I was pretty sure that I heard the heart beating very feebly and rather frequently, but only for a few seconds, after which no sound could be heard. There were one or two more very feeble inspirations at intervals of about a quarter of a minute, after which there were no further signs of life. As soon as the patient had entirely ceased to breathe, artificial respiration was performed, but no sign of returning animation appeared.
At the examination of the body fifty-two hours after death, the heart was found to be larger than natural, and there was a good deal of fat on its surface. Its right cavities contained air or gas, probably resulting from the partial decomposition of the blood. The right ventricle was dilated, and its walls were very thin. At one place, near the apex, they were extremely thin. The left ventricle was also dilated, but its walls were of the proper thickness. They were, however, like those of the other ventricle, very soft and friable. There was a calcareous incrustation on one of the aortic valves. There was scarcely any blood in the heart, but its lining membrane was stained in places, showing that blood had been present after death.
Mr. Pollock and the late Mr. W. F. Barlow examined the structure of the heart under the microscope, and the latter gentleman furnished me with the following account of the examination:—
“Many of the fibres have been converted into fat completely; in others, fatty degeneration was beginning. The degeneration, which was in various stages, appeared very general. The fasciculi were broken up, here and there, into masses of small irregular fragments, as they may be found frequently in hearts of this kind. Some large fat globules lay between and upon the fibres. A few fibres showed their transverse striæ plainly, and made the changes in the others look the clearer. On the whole, it may be said that the structure of the organ was greatly damaged, and that its action, consequently, was liable to cease suddenly from slight causes.”
I am of opinion that this patient did not die from the direct effects of the chloroform. The air he was breathing just before he died did not contain more than three or four per cent. of vapour of chloroform at the utmost, and he had previously breathed quite as much, both during the same operation and on previous occasions. The patient seemed to be holding his breath at the moment when his heart ceased to beat; and it is whilst holding the breath, and making a straining effort, that patients labouring under disease of the heart not unfrequently expire. Mr. Pollock, who was present when the patient died, expressed to me his belief that he died of his heart disease, and not of the chloroform.
After reflecting on this case, I see no reason to regret the course which was pursued. It was the opinion of Mr. Hawkins that the patient could not have borne the operations without the chloroform; consequently, if we had decided not to permit its use any more, in consequence of the alarming syncope which occurred after the operation under its influence on December 4th, 1851, he would probably have died in great suffering from the calculus, instead of having seven or eight months freedom from the complaint. And, on the other hand, if it had been decided to operate without chloroform, it by no means follows that the patient would have been in less danger, judging from what I have observed of the effect of pain on the circulation, as compared with the effect of the chloroform carefully administered, in numerous other cases of disease of the heart.
On May 11th, 1854, a patient died suddenly in St. George’s Hospital as she was beginning to inhale chloroform. She was a pale and delicate looking woman, aged thirty-seven, from whose left breast Mr. Cæsar Hawkins was about to remove a mammary glandular tumour. “On entering the operating theatre she appeared nervous. Having been placed on the table on her back, in a half reclining position, the administration of chloroform was commenced. Dr. Snow’s inhaler was used. The quantity of chloroform placed in the receiver was a little more than a drachm; and the valve for the admission of air was left wide open. Apparently, from excitement, she did not inhale well, but drew her breath by deep catches, and irregularly. Mr. Potter, noticing this, spoke to her, begging her to compose herself, and try to breathe more quietly. The valve was then slightly turned on, in order that she might inhale but a very small quantity of chloroform. The same spasmodic efforts at inspiration still continued; very shortly afterwards, at most not more than a minute and a half from the commencement of the inhalation, Mr. Potter noticed her breathing to suddenly cease, and that she had become deathly pale. The inhaler was at once removed. On placing the finger on the wrist, no pulse could be found. Endeavours to arouse her by dashing the face and chest with water were immediately adopted; but, proving ineffectual, artificial respiration was commenced within a minute of the first symptoms. During the interval, two sighing attempts at inspiration had been observed; but there had been no pulse whatever; the mouth lay a little open, and the countenance was still extremely pale.”[[130]] Other attempts at resuscitation were made without effect.
“At the post-mortem examination, on the following day, no very noticeable lesions of the viscera were discovered. There was congestion of the whole venous system, and the blood, in every organ, was of a deep purple colour, and quite fluid. The brain substance itself was perhaps a little more vascular than usual, and the veins of its meninges were loaded with blood. The heart was small and fat, the right ventricle being especially loaded with adipose material, and its muscular layer much thinned. Under the microscope there was found to be slight, yet decided, fatty degeneration of the muscular structure. Both chambers, but more particularly the right, were distended with blood in which no coagula could be found. The posterior lobes of the lungs were somewhat congested, but not more than the position in which the corpse had lain might account for. There was no disease of the abdominal viscera.”[[131]]
I made a chemical examination of some blood obtained from the heart and large vessels, and also of portions of the lungs and liver, but I failed to detect any trace of chloroform, although the process I employed is one by which I have very easily detected it in the bodies of small animals killed by it, and also in portions of limbs and tumours removed whilst the patients were under its influence to the usual extent.
It was impossible that this patient could have breathed air strongly charged with vapour. Every one in the operating theatre was a witness that the expiratory valve of the face-piece was not, at any time, more than one-third closed, being two-thirds open. In this way no great effect of any kind can be produced, as very little of the air which the patient breathes passes through the inhaler. Mr. Potter informed me, moreover, that the patient breathed very little even of air, her breathing was so much embarrassed by her frightened condition. He was trying to calm her apprehensions at the moment when she died.
The mental emotion under which the patient was labouring was, no doubt, the cause of the sudden death in this instance, as in that above referred to, which occurred at Mr. Robinson’s. The mode of dying, in the present instance, was evidently by cardiac syncope; the same mode of death, in fact, as that which is occasioned by vapour of chloroform, when not sufficiently diluted; and it is only the absolute knowledge, that any small quantity of vapour which this patient inhaled was very largely diluted with air, that enables one to decide, with confidence, that the chloroform was not the cause of death. It may be observed, however, that there was an absence of the convulsive start or spasm which occurred in all those deaths from chloroform, which took place at the beginning of the inhalation, without loss of consciousness having been first induced.
The right cavities of the heart were found full of blood in this case, and it is probable that they became so much distended, as the patient was in a state of alarm, and scarcely breathing, that, in the thin and diseased state of the walls of the right ventricle, the action of the heart was arrested. Sudden death not unfrequently takes place during mental emotion, and, in many of the cases, the mode of dying is probably that just mentioned.
