Comparison between hyperbaric bupivacaine with fentanyl and hyperbaric levobupivacaine with fentanyl in spinal anaesthesia for infraumbilical surgeries- a hospital based randomized controlled trial

Abstract

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