A comparison of 1% ropivacaine with a mixture of 0.75% bupivacaine and 2% lignocaine for peribulbar anaesthesia
In a single centre, randomised, double-blind study, 54 patients underwent intraocular surgery under peribulbar anaesthesia with either ropivacaine 1% or a mixture of bupivacaine 0.75% and lignocaine 2%, both with hyaluronidase 7.5 iu.ml−1. There were no significant differences in volume of anaesthetic required, time to onset of block, peri-operative pain scores or frequency of adverse events between the ropivacaine group and the lignocaine and bupivacaine group.
