Ropivacaine plus lidocaine versus bupivacaine plus lidocaine for peribulbar block in cataract surgery: A prospective, randomized, double-blind, single-center, comparative clinical study.
Abstract
Cataract surgery in ophthalmology is usually done under peribulbar block with a mixture of 0.5% bupivacaine and 2% lidocaine. Several case reports of fatalities associated with bupivacaine has necessitated a search for alternative safe agents. The aim of this study was to compare peribulbar block characteristics using a mixture of 0.5% bupivacaine and 2% lidocaine with a mixture of 0.5% ropivacaine and 2% lidocaine.
