Abstract
The efficacy and safety of hyperbaric ropivacaine with hyperbaric bupivacaine in spinal anesthesia for lower abdominal surgeries is of interest. Both agents produced reliable sensory and motor blocks; however, ropivacaine exhibited a slower onset, a less extensive sensory block and a faster regression compared to bupivacaine. The duration of the motor block was significantly shorter with ropivacaine. Hemodynamic changes and side effects were similar in both groups. Ropivacaine's favorable recovery profile, including quicker micturition, suggests its potential for daycare surgery. However, the non-availability of a standard densitometer and the need for aseptic preparation of hyperbaric ropivacaine is the limitation.
