Comparison of 0.5% hyperbaric bupivacaine and 0.5% hyperbaric levobupivacaine with Buprenorphine as an adjuvant for spinal Anaesthesia in adults undergoing infraumbilical Surgeries – a one year hospital based randomized Control trial

Abstract

Context: Spinal anaesthesia with hyperbaric bupivacaine is commonly used, while hyperbaric levobupivacaine is less studied. We aimed to compare hemodynamic effects and the onset of sensory and motor block between these formulations when used with buprenorphine. Aims: To assess hemodynamic parameters and to compare onset of sensory and motor block of buprenorphine with hyperbaric formulations of bupivacaine and levobupivacaine in spinal anaesthesia for infraumbilical surgeries.
