Comparing Buprenorphine and Nalbuphine as Adjuvants to Intrathecal Bupivacaine: Haemodynamic Effects in Infraumbilical Surgeries

Dr. Eleena John, Dr. M. Paul Wilson

Abstract: Background: To compare the haemodynamic effects and side effects of spinal anaesthesia when buprenorphine or nalbuphine is used as an adjuvant to intrathecal bupivacaine in patients undergoing infraumbilical surgeries. Methods: 40 patients were divided into two groups of 20 each. Group BBpatients were given 0.2ml 60 mcg buprenorphine along with 2.8 ml 0.5% hyperbaric bupivacaine. Group BNpatients were given 0.2ml 2 mg nalbuphine along with 2.8 ml 0.5% hyperbaric bupivacaine. Results: No significant differences in the haemodynamic effects and side effects between group BB and group BN. Conclusion: In elective infraumbilical surgeries, the addition of buprenorphine to intrathecal bupivacaine does not cause significant haemodynamic variations or side effects than the addition of nalbuphine to intrathecal bupivacaine.
