Our aim was to compare the clinical efficacy of 0.5% hyperbaric ropivacaine and 0.5% hyperbaric bupivacaine with regard to onset of sensory and motor blockade, total duration of blockade and recovery profile of patients undergoing below umbilical procedures under spinal anaesthesia. Eighty subjects were randomized into 2 groups .40 patients in group A received 3 ml of 0.5% hyperbaric ropivacaine with glucose 8.33% and 40 patients in group B received 3 ml of 0.5% hyperbaric bupivacaine. Intraoperative vitals were recorded. Onset of sensory block after 5 minutes and time taken to achieve maximum sensory blockade was assessed. Time to complete motor block and total duration of motor block were compared during the procedure. Total duration of sensory block was also noted. We found that onset of sensory and motor block was earlier with bupivacaine as compared to ropivacaine (P<0.001). The total duration of sensory and motor blockade was less with ropivacaine (P<0.001).The time taken for mobilization and first micturition was earlier with ropivacaine (P<0.001). The incidence of hypotension was lower with ropivacaine (P<0.05).Thus, 0.5% hyperbaric ropivacaine seems to be a promising agent for intermediate duration day care procedures under spinal anaesthesia.
