Abstract

Background & aim: Interscalene brachial plexus block provides efficient analgesia after arthroscopic shoulder surgery. But it is associated with a greater occurrence of unilateral diaphragmatic paralysis. This may add to patient dissatisfaction and also may not be tolerated well by patients having respiratory diseases. We have compared the efficacy of costoclavicular block (CCB) with interscalene block (ISB) for postoperative analgesia in patients undergoing arthroscopic shoulder surgery. Methods: Fifty patients were randomly divided in to two group of 25 each (ISB or CCB group). 20 mL of levobupivacaine (0.5%) with 4 mg of dexamethasone were used in both ultrasound guided ISB and CCB. Numerical rating scale (NRS)scores for pain was assessed at 0.5, 1,2, 4, 6, 12, and 24 hr in postoperative period. The mean onset time, time to first analgesia request, total analgesic requirement for 24 hrs postoperatively, patient satisfaction, incidence of hemidiaphragmatic paralysis and any other complications were recorded.
