Abstract

Background: The low toxicity of ropivacaine makes it attractive for peribulbar anaesthesia.

Aims and Objectives: To compare the anaesthetic efficacy of 0.75% ropivacaine and 2mg dexamethasone with 0.5% bupivacaine and 2mg dexamethasone as a peribulbar block in cataract surgery.

To compare the efficacy of 0.75% ropivacaine and 2mg dexamethasone with 0.5% bupivacaine and 2mg dexamethasone dexamethasone to assess the akinesia, analgesia, IOP and post op inflammation in peribulbar block.

Materials and Methods: Randomised double blinded study among 50 patients hospitalized for cataract surgery. , iop at 0,1,5 and 10 min was noted after block

Residual ocular movement and VAS(visual analogue scale) score was recorded at 0, 1, 5 and 10 minutes interval after the block.Post op inflammation was noted by Ac cell grading

Conclusion: We would conclude by our study that ropivacaine with dexamethasone showed faster onset of akinesia  and lowering iop, But bupivacaine with dexamethasone group showed prolonged post operative akinesia, better post operative analgesia and prolonged time to first rescue analgesia, post operative inflammation

Keywords: ropivacaine, bupivacaine, dexamethasone, akinesia, analgesia, IOP, post op inflammation.
