ABSTRACT
Bupivacaine as local anaesthetic has cardiovascular and neurological toxic effects; ropivacaine on the other hand is known to have fewer side effects. Its safety and some its ability to reduce intra ocular pressure has led to its widespread usage. The aim of our study was to compare the efficacy of inj. Ropivacaine 0.75 % + hyaluronidase 50 IU / mL with inj. bupivacaine 0.5 % + hyaluronidase 50 IU / mL in cataract surgeries under regional anaesthesia. MethodsWe evaluated 60 patients who were posted for small incision cataract surgeries. They were randomly divided by drawing chits in to 2 groups according to the anaesthetics used (ropivacaine / bupivacaine). Evaluation of these patients was done on the basis of sensory onset, motor onset using akinesia score, requirement of rescue analgesic, and time of motor and sensory offset of the local anaesthetic. ResultsInj. ropivacaine 0.75 % showed greater reduction in IOP (p < 0.05). Other parameters such as motor block, sensory block, akinesia score, and requirement of rescue analgesia were comparable between the two groups (p > 0.05). ConclusionsIn patients posted for intra ocular / cataract surgeries, ropivacaine 0.75 % and bupivacaine 0.5 % are comparable, with ropivacaine having better haemodynamic profile and also reduces intra ocular pressure.
