Abstract

The aim of this study is to study on the efficacy of levobupivacaine with buprenorphine in comparision to levobupivacaine Alone in ultrasound guided supraclavicular brachial plexus block. Eighty ASA Physical status grade 1 and grade 2 patients of either sex between 18 to 60 year of age and bmi 18.5 to 30 under going elective upper limb surgery in anesthesia department of Chirayu Medical College & Hospital Bhopal O.T. CMCH Tertiary Care Center Bhopal, M.P. Result: It was observed that addition of Buprenorphine as an adjuvant to local anesthetics for brachial plexus makes sensory (8.30±2.40 mins) and motor (12.30±4.02 mins) onset earlier than plain local anesthetic agent (sensory 12.30±2.80 mins and motor 14.50±4.04 mins) used. The duration of sensory (8.12±1.30 hrs. and 14.50±3.20 hrs) and motor (10.80±1.52 hrs. and 16.52±3.36 hrs) block was significantly longer in the Buprenorphine group than in the control group (p-value < 0.001). All patients in both groups remained hemodynamically stable with no significant difference in vital parameters at all times. The postoperative pain score and the number of patients who required rescue analgesics and mean number of supplemental analgesics required were also significantly lower in Buprenorphine group as an Adjuvant to local anesthetics. Conclusion: It was concluded that the addition of 150µg (0.5 ml.) of Buprenorphine to 0.5% Levobupivacaine effectively and safely shortens the onset of sensory and motor blockade, increases the duration of sensory and motor blockade and increases the duration of postoperative analgesia without any hemodynamic disturbances
