ROPIVACAINE VERSUS BUPIVACAINE-LIGNOCAINE MIXTURE IN PERIBULBAR BLOCK- A COMPARATIVE STUDY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 48
Abstract
BACKGROUND Ropivacaine is a newer local anaesthetic agent with low systemic side effects. It has the potential advantage of reduced cardiovascular and neurological toxicity compared with other available local anaesthetics that are commonly used for peribulbar anaesthesia. In this study, we intend to compare the efficacy of Ropivacaine as against Bupivacaine-Lignocaine mixture in peribulbar anaesthesia. MATERIALS AND METHODS A prospective, randomised study was conducted on 100 patients undergoing elective cataract surgery by phacoemulsification under peribulbar block at Dr. Sushila Tiwari Memorial Hospital, Haldwani. Patients were randomly allocated to two groups of 50 patients each, Group 1 (Bupivacaine + Lignocaine) and Group 2 (Ropivacaine). In all cases peribulbar block was achieved by injecting 7 - 10 mL of the drug. Both groups were compared with respect to intraocular pressure change, onset of akinesia, postoperative pain and haemodynamic status after application of peribulbar block and surgeon’s satisfaction at the end of surgery. RESULTS The demographic data of the patient and surgical duration were similar in both groups. Ropivacaine showed statistical significance in reduction of intraocular pressure and onset of akinesia 10 mins after the block. No significant difference was observed in haemodynamic status after the block. Both groups showed similarity in post-operative pain assessment and surgeon’s satisfaction at the end of surgery. CONCLUSION It is inferred from our study that Ropivacaine is a good alternative for peribulbar anaesthesia compared to bupivacaine/lignocaine as it has a better safety margin, faster onset and lesser toxic effects than other comparable local anaesthetic agents.
