Comparative Evaluation of 0.75% Ropivacaine with Ropivacaine 0.75% and Clonidine in Combined Sciatic Femoral Nerve Block for Orthopedic Leg Surgeries

Ropivacaine & Clonidine in Combined Sciatic Femoral Nerve Block

Abstract

Background: The present study compared between ropivacaine and ropivacaine with clonidine in lower limb orthopedic surgery using sciatic-femoral block. Subjects and Methods: The present study was conducted in the department of Anaesthesiology on 60 patients undergoing elective lower limb orthopedic surgery. Patients were divided into 2 groups of 30 each. Group I (Ropivacaine Group) Patients in whom sciatic femoral block was achieved using 30 mL 0.75% Ropivacaine alone. Group II (Ropivacaine + Clonidine Group) Patients in whom sciatic femoral block was achieved using 30 mL 0.75% Ropivacaine plus 1 g/kg clonidine. In both groups, sensory and motor blocks, intraoperative systolic and diastolic blood pressure and VAS score was recorded. Results: In our study mean age, mean weight and mean height and mean duration of surgery were non- significant between both groups. The onset of sensory and motor block was non- significant between two groups. The sensory and motor block characteristics have been found to be no difference in both groups that are matched with the block characteristics of hyperbaric ropivacaine versus ropavacaine with clonidine. Conclusion:  Authors found that ropivacaine 0.75% used in combined sciatic femoral nerve block is well tolerated and provides effective surgical anesthesia as well as relief of postoperative pain. Clonidine as an adjuvant to ropivacaine enhances the quality of combined sciatic femoral nerve block by faster onset of sensory and motor block.
