Ultrasound guided supraclavicular block has emerged as an effective and feasible mode of providing analgesia in upper limb surgery. Participants were allocated to two equal groups of 60 each using a computer generated random number list. Group A patients received 25ml of 0.5% Levobupivacaine with 1mcg/Kg IBW of fentanyl (addressed as LF in the study) and Group B patients received 25ml of 0.5% Levobupivacaine and 1mcg/Kg IBW of Dexmedetomidine (addressed as LD in the study).
