Anaesthol, a fairly stable combination of chloroform, ether and ethyl chloride in molecular proportions, is given by the drop method, but in slightly greater quantity than pure chloroform. For the average “interval” case of appendicitis, for example, about 15 to 20 cc. should be used for the induction, and 40-60 cc. for the entire narcosis. [Sidenote: Morphine Breathing] The morphine, in susceptible individuals, sometimes causes very shallow respirations so that the conduct of the anesthesia to the stage of unconsciousness becomes prolonged because the patient does not inhale sufficient of the anesthetic at each breath. Crowding would be incorrect. The solution is patience, and a little _ether_ to excite deeper respirations. The patient has but a slight stage of excitement, often none at all. The narcosis is continued until the first unimpeded, snoring respiration is heard, and then the surgeon may begin. Much of the narcotic is not required and the anesthesia can be so conducted that the patient promptly becomes conscious after the placing of the last suture. [Sidenote: After-effects] Post-anesthetic distress is, on the whole, less marked than with pure ether. Not infrequently there is neither nausea nor vomiting. MINOR ANESTHESIA WITH ETHYL CHLORIDE. [Sidenote: Office Anesthesia] In surgical office work, there is occasionally the need of a rapid and fleeting anesthesia which does not necessitate the use of a cumbersome apparatus for its induction. In these cases, in place of chloroform, anaesthol or ether, the ethyl chloride spray can be used on the Schimmelbusch mask already described. It produces a prompt anesthesia during which an abscess can be opened, washed and dressed without causing the patient the slightest pain. INTUBATION ANESTHESIA. In intubation anesthesia, or tube anesthesia, as it might be called, the patient does not receive the anesthetic directly from a cone or mask. It is inhaled through a soft rubber tube which is introduced into the pharynx through the nostril or mouth. It is most successful in cases that do not require a very profound narcosis. It is indicated in operations on the head, enabling the anesthetist to be at a distance from the field of operation and out of the surgeon’s province. An important preliminary is to give the patient morphine sulphate, gr. ¼, hypodermatically one half hour before anesthesia is begun, as much less of the anesthetic is then required.
