Background: Dexmedetomidine reduces anaesthetic requirement and have analgesia without respiratory depression. We designed this study to evaluate peri-operative effects of Dexmedetomidine when added to lignocaine in Bierís block.
Materials and Methods: Sixty patients randomly allocated in two groups L and D, receiving 40ml of 0.5 % lignocaine alone and 40 ml 0.5 % lignocaine with 1 ml of 0.5 mcg/kg Dexmedetomidine respectively. During study hemodynamic changes, onset of sensory and motor block, time of tourniquet pain, post-operative analgesic duration and sedation were noted.
Result: Shortened sensory and motor onset time, delayed tourniquet pain, prolonged intra-operative and post- operative analgesic duration with reduced analgesic requirement in D group compared to L group.
Conclusion: We conclude that addition of 0.5 mcg/kg Dexmedetomidine to 40 ml of 0.5% lignocaine in Bierís block improve quality of anaesthesia and peri-operative analgesia without any side effects.
