Aim: This prospective study of adjuvants for supraclavicular brachial plexus block by comparing Clonidine and Dexamethasone. The aim was to ascertain which of them is a better adjuvant. Materials and Methods: This prospective, randomized study was carried out in the Department Department of anesthesia. Study population was randomized to 2 groups of 60 patients each. Group 1 was given 5 ml of 2% lignocaine and 15 ml 0.5% bupivacaine with 8mg dexamethasone. Group 2 received 5ml 2% lignocaine and 15 ml 0.5% bupivacaine with 0.150 mg clonidine. Time to establishment of sensory & motor block, duration of analgesia and any adverse effects were observed. Results: Onset of sensory blockade was at 8.13±5.14 in group 1 and 9.36±2.58 minutes in Group 2. Average time to motor block was at 9.48±3.12 minutes in Group 1 and 10.58±3.61 minutes in Group 2. Analgesia’s duration in Group 1 and Group 2 was 999.2±337.5 and 880.3±283.5 minutes respectively. No major adverse events were seen in either group. Conclusion: Performance of dexamethasone was similar to clonidine as adjunct to local anaesthetic in subclavian perivascular approach of brachial plexus block. However, it has faster sensory and motor blockade’s onset. Analgesia’s duration observed was found to be longer, though the difference was statistically insignificant.
