During the past two years, we had 80 cases of intravenous lidocaine anesthesia for upper limb operations. Per kilogram of body weight, we usually used 1.0~3.0mg of 0,5~0.8% lidocaine and a pressure of 200~300 mmHg(about 100 mmHg higher than the patients systolic blood pressure) by means of an Inflato-Matic dual cuff tourniquet which was also connected with an Inflato-Matic 2, 000 Tourniquet Regulator and oxygen tank. Analgesia occurred about 5 10 minutes after injection with relative satisfaction and, fortunately, no kind of serious complications ensued after releasing the tourniquet. It is not only a simple technique and of low cost to give the anesthesia to the patient(in-patient or out-patient), but also it is possible to perform anywhere and at any time without serious complications or complexities of any other method of anesthesia.
