Abstract :

120 ASA I and II patients scheduled for upper limb surgeries under supraclavicular achial plexus block were divided into two equal groups in a randomized, double–blinded fashion. Group C received clonidine 50 μg and Group D received dexmedetomidine 50 μg added to bupivacaine 0. 5% 25 ml. Results: Onset of motor block was faster in Group C while onset of sensory block was comparable .The durations of sensory and motor block were 225+/–50.34 and 287+/–65.74 min, respectively, in Group C, whereas they were 400+/–100.86 and 482+/–84.56min, respectively, in Group D. The duration of analgesia was 292.78+/–67.45 min, significantly less in Group C compared to 492.24+/–108.45min in Group D (P < 0.001). The quality of anesthesia was significantly better in dexmedetomidine group compared to clonidine group (P < 0.001).Conclusion: Dexmedetomidine is the better adjuvant for supraclavicular block when compared to clonidine.
