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.
