AIM: To compare the efficacy of Bupivacaine 0.25% with and without dexamethasone in parascalene block for upperlimb surgeries in mims medical college , vizianagaram ,AP. MATERIALS AND METHODS :Patients undergoing upperlimb surgeries under Parascalene block by 22G nerve locator were randomly allocated into two groups of Group B who receives 30ml of Bupivacaine 0.25% and Group BD who receives 28 ml of Bupivacaine 0.25% with 8 mg of dexamethasone. The duration of analgesia is compared as the primary outcome.other parameters like time of onset of sensory and motor blockade,post operative VAS scores were compared as the secondary outcome. RESULTS : The mean duration of analgesia is significantly prolonged in Group BD with mean time of 595.43 min compared to Group B where it was 311.40 min.The mean onset of sensory block was significantly shortened in Group BD with mean onset time of 4.67 min compared to Group B where it was 7.67 min. The post operative VAS score was significantly lesser in Group BD where it was 3.55 compared to Group B where it was 4.09. CONCLUSION :Addition of 8 mg of Dexamethasone to 0.25% Bupivacaine 28 ml for parascalene block, quickens the onset of Sensory and motor blockade and prolongs the duration of analgesia with improving the quality of post operative analgesia.
