Abstract: Background: The aim of this study was to compare the effects of dexmedetomidine and clonidine used as adjuvants to 0.5 % hyperbaric bupivacaine in lower limb orthopaedic surgeries under spinal anaesthesia. Material and Methods: The prospective clinical study ? Randomized controlled trail was conducted in ninety patients of any gender divided in three groups. In Group - C, Group - D, Group - N (n=30 each) patients received 50mcg of Clonidine (0.5ml), 5mcg of dexmedetomidine and 0.5ml normal saline along with 12.5mg of hyperbaric bupivacaine respectively for spinal anaesthesia. These groups were compared using one - way analysis of variance (ONE - WAY ANOVA) and difference between the groups compared using unpaired T - test. Results: Duration of analgesia was more with intrathecal dexmedetomidine. Conclusion: We concluded that the supplementation of bupivacaine with dexmedetomidine 5?g or clonidine 50?g in spinal anaesthesia produces significantly shorter onset of motor and sensory block with longer duration of sensory and motor block when compared to bupivacaine alone. Amongst dexmedetomidine and clonidine, dexmedetomidine shows significantly longer duration of analgesia than clonidine which proves it to be better adjuvant than clonidine at the mentioned dose.
