Abstract:
We studied 20 outpatients undergoing surgery of the extremities with regional intravenous anesthesia (RIA). In our study RIA vas performed with the help of a double tourniquet in order to prevent adverse reactions; the drug of choice was lidocaine, because we considered it more suitable for this kind of procedure. The technique was of simple execution and well tolerated by the patient. This technique maker it possible to perform surgery of forearm and foot with a small amount of anesthetic even in outpatients.
