Abstract
The axillary approach to brachial plexus is a recognized anaesthetic technique for operations of upper extremities specially when patient is unprepared or unfit for general anaesthesia. Continuous brachial plexus block is a valuble technique for prolonged surgery of the upper extremity and also for continuous postoperative analgesia. Analgesic response can be increased by addition of opioids e.g butorphanol to the local anaesthetic in the brachial plexus sheath to control post-operative pain. In this research, we studied fourty patients undergoing elective upper extremity surgery (ASA I & 11). Axillary brachial plexus block was established by injection of 30 ml 1.5 % mepivacaine after repeated aspirations using axillary brachial plexus catheter. Surgery was started when complete analgasia was obtained, mepvacaine 10 ml 1.5 % was given via the catheter in brachial plexus sheath every 90 min. when needed. Sedation was provided by midazolam 2-5 mg when needed.
