    Abstract: <p style="text-align:justify">The this study was to compare two approaches (coracoid and clavicular) regarding success rate, discomfort during performance of block, tourniquet tolerance and complications. This randomised brachial plexus in infra clavicular region can be blocked by various approaches. Aim of, controlled, prospective study included sixty adult patients of both sexes of ASA status 1 and 2 randomly assigned to receive nerve stimulator guided infra clavicular brachial plexus block either by lateral coracoid approach (group A, n=30) or medial clavicular approach (group B, n=30) with 25‐30 ml of 0.5% bupivacaine. Sensory block in the distribution of five main nerves distal to elbow, motor block (Grade 1‐4), discomfort during performance of block and tourniquet pain were recorded. The depth of insertion was less with corocoid approach group when compared to clavicular approach group. Time taken to perform block was shorter in corocoid approach group when compared to clavicular approach group. Onset of both sensory and motor blockade were similar in both the groups. Successful block was achieved more with corocoid approach group than with the clavicular approach group. Tourniquet tolerance was found to be better with corocoid approach group than with the clavicular approach group. Complications like vascular puncture was similar in both the study groups. Infra clavicular brachial plexus block using corocoid approach provides an adequate sensory and motor blockade, easy to perform with high success rate, good tourniquet tolerance and less complications when compared to that using clavicular approach.</p>
