A Comparitive Study of 2% Lidocaine Plus 0.5% Ropivacaine Versus 2% Lidocaine Plus 0.5% Bupivacaine for Peribulbar Anesthesia in Cataract Surgeries
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 11
Abstract
Introduction: The goals of safe and effective anesthesia for intraocular surgery are to obtain good analgesia and akinesia without complications. Study aimed to determine efficacy and adverse cardiac effects of 2%lidocaine plus 0.5%ropivacaine in peribulbar anesthesia for cataract surgeries. Material and Methods: In this study, 60 consenting patients posted for cataract surgery under Peribulbar anesthesia with two point injection technique were included. They were randomly categorized into two groups of 30 patients each. One group received ropivacaine with lidocaine and the other group received bupivacaine with lidocaine. Results: Based on our observations regarding onset of action, duration of anesthesia, early recovery of motor blockade and intraocular pressure changes, Ropivacaine scored better than bupivacaine. There were no differences in effects on mean arterial pressure and ECG rhythm changes and even though bupivacaine decreased heart rate from baseline value, bradycardia did not occur in both groups. Conclusion: Ropivacaine is a better agent than bupivacaine for peribulbar anesthesia due to its faster onset and shorter duration with less effects on intraocular pressure.
