Continuous axillary brachial plexus block for postoperative pain relief intermittent bolus versus continuous infusion

Abstract

Background and Objectives. The aim of this study was to compare the efficacy and safety of continuous axillary brachial plexus block by infusion and by intermittent injection of bupivacaine 0.25% in the management of postoperative pain. Methods. Two methods of continuous axillary brachial plexus block for pain management were compared in a prospective randomized trial. Twenty 16- to 62-year-old male patients (ASA I and II), undergoing microsurgery, received 0.25% bupivacaine following surgery, by either continuous infusion (group C, n=10), or intermittent hourly bolus (group B, n=10), via an axillary brachial plexus catheter inserted prior to operation.
