Abstract :

BACKGROUND: Brachial plexus blockade is a time–tested technique for upper limb surgeries. The classical approach using paresthesia technique is a blind technique and may be associated with a higher failure rate and injury to the nerves and surrounding structures. Ultrasound for supraclavicular achial plexus block has improved the success rate of the block with excellent localization as well as improved safety margin. Hence, this study was planned for compå efficacy of extrafascial Vs subfascial deposition of local anaesthetic in ultrasound guided supraclavicular achial plexus block in terms of block time, readiness for surgery, duration of analgesia, duration of motor block. METHODS: 60 patients were selected and divided into two groups Subfacial group: drug: 15 ml [7.5ml of 2% lignocaine with adrenaline and 7.5mlof bupivacaine] under ultrasound guidance and Extra fascial group : 15 ml [7.5ml of 2% lignocaine with adrenaline and 7.5 ml of bupivacaine] under ultra sound guidance block time, readiness for surgery, duration of analgesia, duration of motor block were observed. RESULTS: The subfascial approach provides faster onset of surgical anaesthesia with lesser amount of local anaesthetics and prolonged postoperative pain relief compared to extrafascial approach in ultrasound guided supraclavicular nerve block
