Abstract
OBJECTIVE: To compare parascalene approach of brachial plexus block with the classical subclavian perivascular approach in patients undergoing upper limb surgeries using nerve stimulator. MATERIALS AND METHODS: Sixty patients (age 20 - 50 years) undergoing upper limb surgeries were randomly assigned to two groups, Group A (n=30) receiving brachial plexus block using subclavian perivascular approach and Group B (n=30) receiving brachial plexus block using parascalene approach. Insulated needles and a nerve stimulator were used with both techniques. Time required for performing the block, onset of sensory and motor block, sensory block to pin prick, success rate, complications and rescue analgesia requirement were compared. RESULTS: Time required for performing the block (4.7±0.92 min vs.2.9 ±0.84 min) were significantly shorter and sensory block level to pinprick is higher (shoulder level), the overall success rates were high, complications and rescue analgesia requirement are low in Group B as compared to Group A. CONCLUSION: Supraclavicular block of brachial plexus by Parascalene approach provides an adequate sensory blockade and motor blockade, with less time to perform block, level of sensory block is higher (upto shoulder), high success rate and less complications when compared to subclavian perivascular approach.
