Group D was administered Hyperbaric Bupivacaine 15mg + Dexmedetomidine 5µg in 0.5 ml normal saline,group F was administered Hyperbaric Bupivacaine 15mg + Fentanyl 25 µg in 0.5 ml normal saline and group C  were administered Hyperbaric Bupivacaine 15mg plus in 0.5 ml normal saline.Duration and quality of sensory and motor block were assessed.
Results: Sensory and motor block in   group D patients were longer than group F and C patients.
Conclusion: Intrathecaldexmedetomidine when added tobupivacaine heavy (0.5%)provide better and prolonged analgesia in comparison to fentanyl.
