ABSTRACT
Introduction: Brachial plexus block is used as a regional anaesthetic technique for elbow, forearm and hand surgery and popular because of its ease, reliability and safety. The addition of opiates to local anaesthetics provides effective and long-lasting analgesia. This study was conducted to compare the effects of adding Fentanyl and Buprenorphine to local anaesthetics in brachial plexus block via the axillary approach under ultrasound guidance.
Materials and Methods: A cross-sectional analytic study was conducted on 48 patients aged 18-60yrs old belonging to ASA I & II posted for forearm, wrist and hand surgeries with axillary brachial plexus block and allotted to 2 groups of 24 each. In both the groups volume of drug used was 25ml.
Group A received 12ml of 2% Lignocaine with adrenaline (1:200000), 12ml of 0.5% Bupivacaine and 50mcg Fentanyl.
Group B received 12ml of 2% Lignocaine with adrenaline (1:200000), 12ml of 0.5% Bupivacaine and 300mcg Buprenorphine. The total duration of motor and sensory blockade with adverse events during the perioperative period were recorded.
Results: The mean total duration of sensory and motor block was prolonged in Group B (TDSB- 306.25+/-10.759, TDMB- 338.75+/-8.373) when compared to Group A (TDSB- 241.67+/-10.286, TDMB- 262.50+/-12.247). There were no serious complications in the perioperative period in any of the groups.
Conclusion: Buprenorphine as an adjuvant to local anaesthetics prolongs the duration of sensory and motor block than Fentanyl without any significant clinical side effects.
