The problem of satisfactory anesthesia for operations about the face and upper air passages is worthy of study. The nature of the operations is such that no inhaler or cone can be kept constantly over the face and nose of the patient. It may be necessary to keep the mouth open throughout the operation. Under these conditions it has been impossible by the usual methods to produce a smooth anesthesia.
The patients have been anesthetized in the following ways:
1. By nitrous oxid or ethyl chlorid: The anesthesia produced by these agents is too short for the majority of the operations.
2. By charging up the patient with ether and allowing him to recover partially as the operation goes on, then repeating this process as many times as necessary: This method is dangerous and seriously impedes the operation.
3. Chloroform administered
