A comparision of intrathecal fentanyl and clonidine as an adjuvant to hyperbaric ropivacaine during sub arachanoid block for lower abdominal surgeries: a prospective randomized clinical trial.

Abstract

ABSTRACT Title: A comparison of intrathecal fentanyl and clonidine as an adjuvant to hyperbaric ropivacaine during subarachnoid block for lower abdominal surgeries: A prospective randomized clinical trial. Context: Spinal anaesthesia with hyperbaric ropivacaine is used. Adjuvants are used with local anesthetics for synergistic effect and for prolonging the duration of sensory and motor block. We aimed to compare onset and duration of sensory-motor block and hemodynamic effects between fentanyl and clonidine when used along with hyperbaric ropivacaine. Aims: To compare onset and duration of sensory-motor block of fentanyl and clonidine with hyperbaric formulations of ropivacaine and in spinal anaesthesia for infraumbilical surgeries and to assess hemodynamic parameters and sedation score.
