A PROSPECTIVE STUDY TO COMPARE THE EFFICACY OF INTRATHECAL FENTANYL WITH BUPIVACAINE IN PATIENTS UNDERGOING LOWER LIMB ORTHOPAEDIC SURGERIES

Abstract

Background: Spinal anaesthesia is the most common neuraxial anaesthesia for infraumblical
surgeries. Various adjuvants are used to enhance the quality and duration of spinal
anaesthesia.
Aims and Objectives: The aim of this study was to evaluate the onset, duration of sensory
and motor block, hemodynamic effects, duration of analgesia and adverse effects of fentanyl
given intrathecally with 0.5% bupivacaine heavy in patients undergoing lower limb
orthopaedic surgeries.
Materials and Methods: This prospective randomized double blinded study was conducted
on total sixty patients undergoing lower limb orthopedic surgeries. They were divided into
two groups of thirty five patients each. Group F received 25 μg fentanyl with 3 ml 0.5%
bupivacaine heavy and group B received 3.0 ml 0.5% bupivacaine heavy. The onset and
duration of sensory and motor blockade, duration of analgesia, haemodyamics, and side
effects were assessed
