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.
