_Lithotomy._ In this operation, it is advisable to have the patient placed on the operating table with his head supported by one or two pillows, and to administer the chloroform before the sound is introduced. This having been done, it is generally requisite to administer a little more vapour cautiously and gently, whilst the bandages are applied to the hands and feet, and the patient is drawn down towards the foot of the table. The bandaging should on no account be neglected in the adult patient. It would be an abuse of chloroform to carry its effects so far in every case that the slightest contraction of the muscles could not be excited by the use of the knife, merely to save the trouble of applying a bandage. In little children, the bandages are not usually employed; but in these cases, the person administering the chloroform should hold the head or shoulders of the little patient, just as the surgeon makes his first incision; for the two assistants who are holding the legs, and think they are doing a great deal of good, are really making a fulcrum to enable the child to push itself away from the surgeon, if it makes the least flinch, which it is almost sure to do, if the narcotism is not much deeper than there is any occasion for. In this operation the patient should be fully insensible when the surgeon makes his first incisions; and the chloroform must be repeated or not during the operation as occasion may require. I have memoranda of fifty-seven cases in which I have administered chloroform in the adult, and thirty-four in children, down to the present time, the end of March 1858. It was my expectation that I should be able to give the result of these, and all the other important operations; but I have in a few cases either not ascertained whether the patient recovered or not, or have neglected to make a note of the circumstances at the time; and although the deficiencies might perhaps be made up by private correspondence, and by searching the books of three hospitals, I regret that I have not time at present for such an undertaking. A large proportion of the above cases of lithotomy were performed by Mr. Fergusson, either in his private practice, or in King’s College Hospital, and the remaining operations were performed by a number of surgeons. On April 19th, 1855, Mr. Fergusson removed eight calculi, as large as pigeon eggs, from the bladder of a gentleman, aged sixty-nine, who had a favourable recovery.
