Abstract

Background: During spinal and epidural anesthesia adding buprenorphine or clonidine as an adjuvant along with local anesthetic agent has given promising results in producing analgesia, whereas the same agent when used for brachial plexus block had shown mixed results. The study aimed to compare the anesthetic and analgesic properties of buprenorphine and clonidine when used as adjuvants along with bupivacaine during supraclavicular brachial plexus blockade.

Methodology: A double blinded randomized controlled trial was conducted for a period of one year. A total of 90 subjects were divided into three groups. All three groups patients received 0.3% bupivacaine as the anesthertic agent, the adjuvant used for group A patients was 1 ml normal saline, group B it was 1 ml of 300 mcg buprenorphine and group C patients received 1 ml of 150 mcg clonidine as adjuvant. Hemodynamic parameters, sensory and motor blockade levels along with the occurrence of adverse events were monitored at regular intervals among all the study subjects.

Results: Hemodynamic parameters were well maintained in all three groups without showing significant differences in the parameters. Patients in the buprenorphine group had an early onset of sensory block along with prolonged duration of block, whereas no significant changes reported with relation to motor block. As such there was no incidence of adverse events in any of the three groups.

Conclusion: Compared to clonidine, buprenorphine was found to be a better adjuvant to bupivacaine for producing analgesic effect.
