A Prospective Comparative Study between 10ml and 15ml of Normal Saline for Epidural Volume Expansion, with 10mg of 0.5% Intrathecal Hyperbaric Bupivacaine for Elective Surgeries Up to Umbilical Level in Adult Patients

INTRODUCTION: The Epidural Volume Expansion(EVE) technique is a modification of CSE, Study is aimed to compare the two Normal saline volumes (NS) (10ml and 15ml) for EVE on spinal anaesthesia with 10 mg of 0.5% hyperbaric bupivacaine for elective surgeries up to umbilical level, with respect to sensory, motor blockade and haemodynamics Methodology: 90 patients of both sexes, aged between 18-60 years, with ASA grade I and 2, are taken and divided into 3 groups, A, B, C(n=30) Group A received 2ml of 0.5% Bupivacaine intrathecally without EVE. Group B received 2ml of 0.5% hyperbaric Bupivacaine and EVE of 10ml NS, and Group C received 2ml of 0.5% hyperbaric Bupivacaine and EVE with 15ml NS. The data obtained was analysed using Cramer's V test, Independent T-test and Anova RESULTS: Maximum level of a sensory blockade is seen in Group C. Time for two-segment regression maximum in Group B, Duration of Anaesthesia is highest in Group B, Duration of Motor Blockade is highest in Group B. Bradycardia, hypotension more in Group C. CONCLUSION: EVE of 10 ml of saline with intrathecal 0.5% Bupivacaine is better compared to EVE of 15 ml of saline with regard to sensory and motor block and hemodynamic stability
