PERIBULBAR ANAESTHESIA IN OCULAR SURGERY: ROPIVACAINE COMPARED TO BUPIVACAINE AND LIDOCAINE COMBINATION

Abstract

Objective: To assess efficiency of Ropivacaine compared with Bupivacaine/lidocaine combination for inducing peribulbar anaesthesia in ocular surgery

Study design: Comparative descriptive study

Place and Duration of Study: Department of Ophthalmology, Avicenna Medical College Lahore from 1st January 2016 to 31st December 2016.

Patients & Methods: A descriptive, study was carried out on 110 patients selected for cataract extraction under peribulbar block. Patients of both sexes aged 40–70 years scheduled for surgery was included in this study after taking written informed consent. They were placed equally in two groups with respect to pharmacological agent (LA) given. Half of the patients receive Ropivacaine for akinesia (Group 1) and other half were given Bupivacaine mixed with lidocaine (Group 2). Nerve block was carried out by injection of 5–7 ml of the respective local anaesthesia in both groups for peribulbar block..

Results: In this study 110 patients were included, 55 patients in Group A, who received local anesthesia with Ropivacaine and 55 patients in Group B who received anesthesia with Bupivacaine plus lidocaine. There were 72 (64.5%) males and 38 (34.5%) females. Visual acuity ranges between 6/60 to hand movement HM+. There was adequate akinesia using Ropivacaine alone, which is comparable to Bupivacaine lidocaine group. Pain score, surgeon or patient contentment between two groups were nearly same.

Conclusion: We concluded that Ropivacaine alone can safely be indicated for effective akinesia by peribulbar block as Bupivacaine combined with lidocaine routinely allows.
