Use of trilene and sombrevin anesthesia in minor gynecologic operations

: In minor gynecological operations a narcotic is needed which is quick-acting and produces a powerful short-term effect without disturbing the contractive ability of the uterus or blood loss and without suppressing the vital functions. Trilene was tested in 400 such operations and sombrevin in 400--mainly curettage and abortions. Sombrevin breaks down rapidly in the organism; thus the patient begins to wake up in 5-8 minutes. The dose depended on the health status of the woman, her weight, and the type of operation. It was introduced at the moment of stretching of the cervical canal so that the maximum extension of the cervix would coincide with the deepest level of anesthesia. Trilene (trichloroethylene) gives a powerful analgesic effect at very small doses. The patient inhales a vapor in a concentration of 0.1-1%. No unpleasant effects are felt, and the mucous membranes are not irritated. There is no subsequent nausea or vomiting. The patients noted no feeling of pain at any time and were in continual contact with the physician during the operation. The side effects of sombrevin and trilene are given in the accompanying table.
