Objectives: The study was undertaken to observe the effect of intrathecally administered fentanyl with bupivacaine on onset and duration of sensory and motor block, quality of anaesthesia and requirement of analgesia during early postoperative period. Method: In this study 45 women of group 1 received hyperbaric bupivacaine 10 mg and 45 women of group 2 received bupivacaine 10mg with fentanyl 12.5 mg. Onset of sensory and motor block, height of block, sensory regression, requirement of analgesic and any complication were recorded. Result: The onset time for analgesia was significantly shorter in group 2 than in group1 (1.9±0.56 vs 2.46± 0.79). The mean time for sensory regression to L1 is shorter in group1 compared to group 2. The mean time for two segments sensory regression was significantly prolonged in group2 compared to group 1. Time for complete sensory recovery when rescue analgesia was required in postoperative period was significantly prolonged in group 2 compared to group 1 (259.4±35.3 vs 165.0±23.8). There were no significant differences between the two groups with regard to incidence of nausea and vomiting, shivering and pruritus. Conclusion: Addition of fentanyl to hyperbaric bupivacaine augments sensory block without affecting motor block.
