BACKGROUNDSciatic nerve block is a useful technique for unilateral lower limb surgeries. Bupivacaine is the most commonly used long acting amide local anaesthetic agent for peripheral nerve blockade. Ropivacaine, a newly introduced amide local anaesthetic is similar to Bupivacaine in structure, less potent than bupivacaine and lacks cardiotoxic potential of Bupivacaine. Hence, this study is taken up to compare the block characteristics of equipotent doses of Bupivacaine and Ropivacaine.
BACKGROUNDSciatic nerve block is a useful technique for unilateral lower limb surgeries. Many studies with different approaches for sciatic nerve block have been conducted to demonstrate the efficacy of sciatic nerve block with different local anaesthetic drugs over the past decades. Ropivacaine, a long-acting amide local anaesthetic is found to be a safe and effective agent of choice for sciatic nerve block. Hence, this observational study was undertaken to evaluate the clinical efficacy of sciatic nerve block for intraoperative anaesthesia and post-operative analgesia in patients undergoing below-knee orthopaedic surgeries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
