Background and Aims: Brachial plexus block is close to the ideal anesthetic technique for upper limb surgeries. Several clinical studies have shown that clonidine prolongs sensory motor blockade when used with bupivacaine but effect of clonidine on ropivacaine is not well defined. Present study was done to evaluate the effect of clonidine 2 μg/kg added to ropivacaine 0.5% in supraclavicular brachial plexus block. Methods: In this prospective, randomized, double blind study total 80 patients of American society of anesthesiologist, (ASA) grade I and II undergoing elective upper limb surgery under supraclavicular brachial plexus block were randomized into two groups. Patients in group 1 (n = 40) received 28 ml of 0.5% ropivacaine and in group 2 (n = 40) received 28 ml of 0.5% ropivacaine with clonidine (2 μg/kg body weight). Onset and recovery time of sensory and motor block, duration of analgesia and quality of block, hemodynamic variables, oxygen saturation and level of sedation were studied in both the groups. All the data were analyzed by using unpaired t test. P < 0.05 was considered significant. Result: Sensory and motor block onset times were similar in both the groups. The mean duration of analgesia was 1016.92 + 170.14 min and mean duration of motor block was 880.54 + 127.99 min in group 2. On comparing both the groups it was found statistically significant (P < 0.000). In group 2 four patients showed mild sedation. Group1 showed more severity of pain than group 2 and it was found to be statistically significant (P < 001). Conclusion: Clonidine 2 μg/kg body weight when added to 0.5% ropivacaine in supraclavicular brachial plexus block significantly prolonged sensory and motor block and provides better post-operative analgesia.
