Co M Parative Study of 0.5% Bupivacaine and 0.5% Bupivacaine Plus Buprenorphine for Brachial Plexus Block

Opioids are well studied adjuncts, although the evidence regarding the analgesic benefit of opioid adjuncts remains equivocal. The effectiveness of 0.5% Bupivacaine and 0.5% Bupivacaine plus buprenorphine into brachial plexus sheath was evaluated. The study was a prospective, randomized, double blind and comparative study carried out; 60 ASA I and II patients undergoing elective upper limb surgeries, aged between 16-70 years were randomly allocated into two groups of 30 each. All patients received 0.5% of Bupivacaine at 2mg/kg body weight. In addition, 30 patients in group B received Buprenorphine hydrochloride (2g/kg). Using VAS score the analgesia was evaluated every hourly for six hours, every two hours for next twelve hours and then every sixth hourly till 48 hours.
