A Randomized Controlled Study Comparing Supraclavicular and Infraclavicular Approaches to Brachial Plexus Block under Ultrasound Guidance for Upper limb Procedures

Brachial plexus block remain the only practical alternative to general anaesthesia for significant surgery on the upper limb. Peripheral nerve stimulation is now being largely superseded by ultrasound – guidance because of the increasing number of advantages. routine assessment done and 40 asa 1&2 patients selected and will be grouped by computer generated randomisation into supraclavicular and infra clavicular group. both the blocks will be performed under ultrasound guidance with 30ml of 0.5%bupivacaine and time of sensory and motor blockade and requirement of first post op analgesia will be****assessed.
