Abstract: Background and Aims: An ultrasound-guided blockade of peripheral nerves is a recent approach for accurate and better-quality nerve blocks, and it lowers block failure and prevents procedure related complications. Supra-clavicular brachial plexus block provides ideal anaesthesia for the upper limb surgeries during surgery by reducing stress response. The aim of the study was to compare the Efficacy of 0.5% Ropivacaine versus 0.5% Ropivacaine with Clonidine in Supra-clavicular Brachial Plexus Block. Materials and Methods: In a prospective randomized control study, 80 adult patients in age group of 18-60 years. Each patient was randomly assigned to one of the two groups of 40 patients each, Group-R patients undergoing supra-clavicular brachial plexus block with Inj. Ropivacaine (0.5%) - 20ml and in Group-RC with Ropivacaine (0.5%) - 20ml + Inj. Clonidine 0.5 mcg/kg in 2ml Normal Saline. The groups were compared regarding the quality of sensory and motor blockade and duration of post-operative analgesia. Results: There was a significant early onset and duration of sensory and motor block and analgesia in Group RC compared to R (p<0.001). No significant side effects were noted. Conclusion: The addition of 0.5 mcg/kg of Clonidine to 0.5% Ropivacaine in ultrasound guided supra-clavicular brachial plexus block confers a significant advantage over plain Ropivacaine in terms of duration of analgesia, quality of blockade and need for rescue analgesia.
