To Compare the Effect of Dexmedetomidine, Clonidine and Fentanyl in Epidural Anaesthesia in Lower Limb Orthopaedic Surgeries When Given as an Adjuvant to 0.75% Ropivacaine.

Abstract

Background & Methods: The aim of the study is to compare the effect of,
Dexmedetomidine, Clonidine and Fentanyl in epidural anaesthesia in lower limb orthopaedic
surgeries when given as an adjuvant to 0.75% Ropivacaine. 90 patients of ASA class I and II,
aged between 20-60 years, of either sex (M & F), scheduled for elective lower limb
orthopaedic surgeries were included in this study.
Results: Time of onset of sensory block was minimum in Dexmedetomidine group i.e.
8.24±0.38 minutes followed by fentanyl group (8.52±0.27 minutes) and clonidine group
(9.45±0.18 minutes) with statistically highly significant difference in onset of sensory
blockade amongst three groups (p<0.0001).
