Abstract :

BACKGROUND: The study was done to compare the efficacy of injection dexmedetomidine versus injection clonidine as an adjuvant to bupivacaine in supraclavicular achial plexus block in adult patients. MATERIALS AND METHODS: 60 adult patients of ASA grade I/II, posted for various elective upper limb surgeries were divided into two groups Group C and Group D.Group C patients received Inj. Bupivacaine 0.5% 20 ml + Inj. Clonidine 1µg/kg and Group D patients received Inj. Bupivacaine 0.5% 20 ml + Inj. Dexmedetomedine 1µg/kg, in supraclavicular achial plexus block. Onset and recovery time of sensory and motor block, duration of analgesia, hemodynamic variables ,sedation and complications were studied. RESULTS: Mean onset time of sensory block and motor block in Group D was significantly lower than Group C. Mean duration of sensory block and motor block was longer in Group D as compared to Group C. Mean duration of analgesia was significantly longer in Group D.There were no any significant incidents of any complications. CONCLUSION: Dexmedetomidine prolongs the duration of sensory and motor block, duration of analgesia, shortens the onset time for sensory and motor block as compared to clonidine when used as an adjuvant to local anaesthetic (bupivacaine) in supraclavicular achial plexus block.
