BACKGROUND: Ropivacaine, a recently introduced local anaesthetic, has approximately 40% reduced potency compared to bupivacaine. The objective of this study was to compare the clinical effectiveness of hyperbaric 0.75% ropivacaine and 0.5% bupivacaine for spinal anaesthesia during lower limb surgeries.

 METHODOLOGY: A randomized double-blinded study was carried out in 60 participants who were divided into 2 groups. Group B were given 2ml intrathecal injection of 0.5% hyperbaric Bupivacaine kg while Group R were given an intrathecal dose of 2ml of 0.75% isobaric Ropivacaine. The variables like time taken for onset of sensory and motor block, duration of the blocks, time taken to reach T10 level were recorded.

 RESULTS: Ropivacaine's slower time to motor blockade onset and shorter motor blockade duration compared to Bupivacaine were both highly significant with P value of 0.0001.

 CONCLUSION: The utilisation of ropivacaine's recovery profile may prove advantageous in situations when immediate mobilisation is necessary.
