Continuous intravenous regional anesthesia

This study evaluates the effectiveness of continuous intravenous regional anesthesia for prolonged operations on the upper extremity. The factors evaluated include patient's sex and age, number of procedures performed, tourniquet on and off times, anesthetic doses, adjunctive drugs used, technical complications, and side effects. Seventy-two procedures were done on 34 patients. The first tourniquet time averaged 58 minutes. Off time averaged 10 minutes. Second tourniquet time averaged 33 minutes, and the mean total tourniquet time was 91 minutes. The mean first anesthetic dose was 275 mg. Mean second anesthetic dose was 128 mg. Mean total anesthetic dose was 402 mg. There were two (6%) technical complications and two (6%) patients had side effects. Continuous intravenous regional anesthesia offers the prolonged anesthesia of brachial plexus block or general anesthesia and the safety, reliability, and ease of intravenous regional anesthesia. Continuous intravenous regional anesthesia should be considered an alternative choice of anesthetic method in upper extremity surgery.
