To compare the effects of adding buprenorphine vs dexmedetomidine in patients undergoing forearm surgeries under supraclavicular brachial plexus block

Abstract

Background: Supraclavicular brachial plexus block is the most commonly employed regional anaesthesia technique for upperlimb surgeries below elbow joint. Many drugs are used as adjuvants to local anaesthetics in order to extend and improve the quality of intraoperative and postoperative anaesthesia. We conducted a study to compare the effects of adding Buprenorphine vs Dexmedetomidine to intermediate-acting local anaesthetic 2% lignocaine with adrenaline in supraclavicular brachial plexus block. Aims and objectives: To compare the effects of adding Buprenorphine vs Dexmedetomidine to 2% lignocaine with adrenaline (1 in 200000) in patients undergoing forearm surgeries under supraclavicular brachial plexus block in terms of onset and duration of sensory and motor blockade, as well as the duration of postoperative analgesia. Materials and methods: 80 ASA Grade 1 & 2 patients aged between 18 and 60 years, of both sexes, undergoing forearm surgeries under supraclavicular brachial plexus block were divided into 2 groups of 40 each. Group A received 7mg/kg of 2% lignocaine with adrenaline + Buprenorphine 3µg/kg. Group B received 7mg/kg of 2% lignocaine with adrenaline (1 in 200000)+ Dexmedetomidine(1µg/kg).
