Abstract
BACKGROUND: Many adjuvants have been tried to enhance the analgesic efficacy of local anaesthetics in supraclavicular brachial plexus block. From previous studies, it was noted that opioids added to local anaesthetics produce comparable analgesia in supraclavicular brachial plexus block. Hence, in my study, I have compared a group of patients who received bupivacaine alone with the other group of patients who received the combination of bupivacaine and buprenorphine. STUDY DESIGN: A total of 60 patients belonging to ASA status I and II posted for elective orthopaedic upperlimb procedures were enrolled and randomly divided into two groups of 30 each. Group I received 24 ml of 0.25% bupivacaine and 1 ml NS Group II received 24 ml of 0.25% bupivacaine and 3μg/kg buprenorphine. VAS score, onset of motor and sensory blockade were observed at fixed interval for 24 hours postoperatively. SPSS 16.01 Version were used for descriptive, analytic and comparative statistics. RESULT: Onset of motor blockade delayed in group II.VAS score were found to be better in group II. Time to first rescue analgesia was prolonged in group II. CONCLUSION: The results showed that buprenorphine enhance and prolong the analgesic effect of bupivacaine when used for supraclavicular brachial plexus block in patients undergoing orthopaedic surgeries.
