Introduction: Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Use of regional anaesthesia which influence the early indicators of recovery such as time to consciousness, the incidence of postoperative nausea and vomiting (PONV), return of full cognitive function, these benefits may occur purely as a result of avoiding opioids, also with using regional anaesthesia, the quality of analgesia and time to first supplementary analgesic is significantly better than that with systemic opioids. Aims and Objective: To evaluate efficacy of hyperbaric ropivacaine versus hyperbaric bupivacaine in Lower abdominal surgeries. Material and Methods: In the presents study two groups were compared undergoing Lower abdominal surgeries. Group I received 3ml of 0.5% hyperbaric ropivacaine and group II received 3ml of 0.5% hyperbaric bupivacaine. Monitoring of vitals and observation for the block parameters were carried out and was compared between these two groups. Results: Ropivacaine has longer onset of action compared to bupivcaine. 9.6 ± 1 min in bupivacaine group while was 9.8 ±1.13 min in ropivacaine group. Ropivacaine has a shorter duration of action compared with buoivacaine it was 176 ± 13.8min for ropivacaine and 213±10.8min for bupivacaine. Ropivacaine had a significant lesser degree of motor blockade compared to bupivacaine. And also total duration of motor block was shorter for ropivacaine (126 ± 17.5) when compared with bupivacaine (195.2±37.7). Conclusion: Ropivacaine produces adequate spinal blockade of shorter duration with early ambulation and faster home discharge as compared with bupivacaine. Thus it can be used intrathecally with equal efficacy and better safety as bupivacaine in similar doses for short surgical procedures.
