Comparative study of 0.5% lignocaine with dexmedetomidine and 0.5% lignocaine in intravenous regional anesthesia
Journal Title: Medpulse International Journal of Anesthesiology - Year 2017, Vol 4, Issue 2
Abstract
Background: Intravenous regional anaesthesia (IVRA) is a simple and reliable technique, with success rates between 94% to 98%. The local anaesthetic most often used is lignocaine. dexmedetomidine, a potent α-2 adrenoceptor agonist is approximately 8 times more selective than clonidine4. Administration of dexmedetomidine as an adjuvant to local anaesthetic has many advantages. In this study we compared lignocaine with lignocaine and dexmedetomidine in IVRA for elective hand and forearm surgeries. Aims and Objectives: To compare onset, quality and duration of sensory and motor block, tourniquet pain, postoperative analgesia, complications and hemodynamic stability after using Dexmedetomidine as an adjuvant. Materials and Methods: 60 Patients undergoing elective hand and forearm surgeries were randomly assigned to Group L (0.5% Lignocaine 200 mg) and Group LD (0.5% Lignocaine 200 mg and 0.5 ug/kg of Dexmedetomidine). Results: Demographic data were comparable. Conclusion: Addition of Dexmedetomidine to lignocaine provides IVRA with quicker onset of sensory and motor block, better quality of anaesthesia, prolonged duration of sensory, motor blockade and postoperative analgesia, delays the onset and severity of tourniquet pain, better hemodynamic stability without any adverse effects.
