Intravenous regional anesthesia with technical modifications is an ideal method of providing anaesthesia for minor surgical procedures to the extremities. It has the advantages of speed of onset, rapid recovery, reliability of blockade & costeffectiveness. Adjuvants to local anaesthetics have expanded the applications of regional anaesthesia by providing faster onset time, inhibition of tourniquet pain, improved peri-operative analgesia and prolonged postoperative analgesia, apart from decreasing the risks of local anaesthetic toxicity. This randomized prospective study of 60 patients, of either sex, between 20-60 years, scheduled for elective or emergency surgeries of upper limb was able to prove that dexmedetomidine as an adjuvant to lignocaine in IVRA has faster onset of sensory and motor blockade, significantly longer postoperative analgesia and lesser incidence of tourniquet pain as compared to Lignocaine alone in surgeries of upper limb
