Comparison of 0.75% Hyperbaric Ropivacaine plus fentanyl versus 0.5% Hyperbaric bupivacaine plus fentanyl, given in lower abdominal and lower Limb surgery

Abstract

Background: Bupivacaine and Ropivacaine are the commonly used drugs in spinal anesthesia. The efficacy of these drugs along with adjuvant fentanyl, remains better but the question remains unsolved that whether bupivacaine plus fentanyl or ropivacaine plus fentanyl, which works better. Hence this study was undertaken to compare the efficacy, hemodynamic stability and side effects of these drugs for lower abdominal and lower limb surgeries.
