About 60 patients of ASA grade I and II undergoing upper limb surgeries were randomly assigned into two groups, Group C and Group NL. In Group C, supraclavicular brachial plexus block was done by conventional subclavian perivascular approach by eliciting paresthesia and in group NL, by the nerve locator guided approach. 15ml of 0.5% bupivacaine and 15ml of 2% lignocaine with 1:2,00,000 adrenaline as the local anaesthetic was used for both the groups. Time taken for the block performed by nerve locator was little longer than the conventional subclavian perivascular technique. The onset of sensory and motor blockade is found to be earlier in the nerve locator technique (7.59±4.35 min and 11.03±4.06 min) compared to the conventional subclavian perivascular technique (11.29±6.23min and13.26±4.25 min).The duration of sensory and motor blockade is found to be prolonged in nerve locator technique (6.56±1.10min and 6.32±1.33min) than conventional subclavian perivascular technique (5.03±1.36 min and 5.04±1.23). Analgesic requirement and Complications were reduced in nerve locator technique compared to conventional subclavian perivascular technique. Nerve locator technique has a higher success rate compared to the conventional subclavian perivascular technique.
