The other cases of necrosis comprise the upper and lower jaw, the parietal bone, the edge of the orbit, the scapula and clavicle, the sacrum, the ileum, and the phalanges of the fingers and toes.
Excision of the Head of the Femur. I have notes of five cases of this operation. They all occurred in children from eight to thirteen years of age. Three of the operations were performed by Mr. Fergusson, one by Mr. Bowman, and one by Mr. French; I also recollect assisting Mr. Henry Smith in a similar operation in a child in 1848, at a time when I did not keep any account of the operations in which I administered chloroform. In one of Mr. Fergusson’s operations, he removed some diseased portions of the acetabulum.
Excision of the Elbow. There is every reason to conclude that this excellent operation has been performed more frequently in consequence of the inhalation of narcotic vapours than it otherwise would have been. I have memoranda of 19 cases of this operation in which I have exhibited chloroform; 18 of them were performed by Mr. Fergusson, and the remaining one was performed by Mr. Coulson, whilst Mr. Fergusson was present.
Excision of the Knee. I have notes of 17 cases in which I have given chloroform during the performance of this operation. Thirteen of the operations were performed by Mr. Fergusson, two by Mr. Bowman, one by Mr. Partridge, and one by Mr. Henry Smith.
This operation had been rarely performed till within the last seven years, and there is every reason to believe that it never would have been frequently performed, if the practice of producing anæsthesia had not been introduced. I shall speak of this operation again in treating of amylene.
Excision of Wrist. There have been two cases of this operation performed by Mr. Fergusson in King’s College Hospital.
The Removal of Tumours of the Upper Jaw. Mr. Syme, Mr. Lizars, and some other surgeons, expressed an opinion at one time that chloroform could not be safely used in this operation, as the blood would be liable to flow into the lungs. This is not the case, however, as the glottis retains its sensibility apparently unimpaired, if the influence of the chloroform is not too deep or long continued. It is only necessary to hold the head forward now and then, when the throat is very full of blood, in order to allow the patient the same opportunity of breathing that he would require if he were awake. A good deal of blood passes into the stomach in great operations about the mouth under the influence of chloroform; and if a few drops pass into the windpipe, they are coughed up again, as they would be in the waking state; there is, however, less appearance of suffocation in operations where the blood flows back into the throat, when the patient is insensible, than when he is awake. The glottis appears to retain some sensibility as long as a creature is capable of breathing, for I have placed the head of more than one cat under water after making them thoroughly insensible with chloroform, and the action of the respiratory muscles lasted more than two minutes, but no water entered the lungs.
I have always made the patient insensible in the usual way, with the inhaler, before the operation of removing tumours of the jaw, and have kept up the insensibility during the operation by means of a mixture of chloroform and spirit on a hollow sponge; or in cases in which I have not been provided with this mixture, I have put not more than fifteen or twenty minims of chloroform on the sponge at one time. Owing to the hands of the surgeon and his assistants being very much in the way, I have not always been able to keep the patient quite insensible throughout the operation. He has sometimes struggled or cried out, but there has been hardly any case in which the patient afterwards remembered any considerable part of the operation.
I have notes of twelve cases of removal of the upper jaw in which I have administered chloroform, in addition to four cases to which I alluded in the Medical Gazette, in the early part of 1849. In some of the cases, the malar bone was removed, as well as the superior maxillary. Eleven of these operations were performed by Mr. Fergusson, and the others were performed by Mr. Partridge, Mr. Henry Charles Johnson, Mr. Hewett, Mr. Henry Smith, and Mr. Haynes Walton.
Mr. Fergusson introduced a great improvement in this operation about seven years ago; instead of the incisions through the cheek or lip, or both of these parts, he merely slits open the lip exactly in the mesial line, as far as the columna of the nose, and then carries the knife along one side of the base of the columna into the nostril, next the tumour. He says: “By opening the nostril in this way as much relaxation was gained as if the knife had been carried from the root of the ala an inch up the side of the nose, and as much facility was given for the future steps of the operation, as if an incision three inches in length had been made through the lip and side of the nose, while a grand object was gained in leaving the slightest possible conspicuous appearance afterwards.”[[146]] This plan has the further great advantage of avoiding the very copious hæmorrhage which arises from a deep incision in the side of the face.
