Abstract

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). Results: Mean time of onset and completion of the sensory block and motor block was significantly lower in LD group when compared to LF group  (p=0.001). Mean total duration of the sensory block and motor block was significantly higher in the LD group when compared to the LF group (p=0.001). Conclusion: Ultrasound guided supraclavicular block using dexmedetomidine 1mcg/Kg IBW  added to 25ml of levobupivacaine 0.5% in patients undergoing upper limb surgery significantly reduced total analgesic consumption in first 48 hours and provided longer duration of analgesia postoperatively compared to levobupivacaine with fentanyl
