Comparison of Butorphanol and Buprenorphine as an Adjuvant to Local Anaesthesia in Supraclavicular Brachial Plexus Block for Post-Operative Analgesia.

Abstract

ABSTRACT: BACKGROUND: Supraclavicular brachial plexus block provides anesthesia for surgeries around elbow, forearm and hand. With advent of opioid receptors, variety of opioid agents is used for postoperative analgesia via brachial plexus block. Butorphanol and Buprenorphine can be used along with local anesthetics to provide post op analgesia. AIMS: 1) To study the onset and extent of sensory and motor blockade. 2) To compare the duration of postoperative analgesia in two groups.
