Addition of dexmedetomidine or lornoxicam to prilocaine in intravenous regional anaesthesia for hand or forearm surgery: a randomized controlled study.
Abstract
Intravenous regional anaesthesia (IVRA) is a simple and cost-effective technique that is ideally suited for surgery involving the distal arm. This study compared the effect of lornoxicam or dexmedetomidine in IVRA with prilocaine in patients who underwent hand or forearm surgery. M ethods: This randomized, double-blind study enrolled 75 patients scheduled for hand or forearm surgery. IVRA was achieved with 2% prilocaine 3 mg/kg in the control group (n=25), 2% prilocaine 3 mg/kg plus dexmedetomidine 0.5 microg/kg in the dexmedetomidine group (n=25), and 2% prilocaine 3 mg/kg plus lornoxicam 8 mg in the lornoxicam group (n=25). In all groups, 0.9% NaCl solution was added to make up a total volume of 40 mL. Sensory and motor block onset and recovery times, haemodynamic variables, visual analogue scale (VAS) pain and sedation scores, duration of analgesia, total analgesic consumption over 24 hours, adverse effects and quality of anaesthesia were recorded. Sensory block onset was shorter and sensory block recovery time longer in the dexmedetomidine group compared with the lornoxicam and control groups (p<0.05). Sensory and motor block recovery times and duration of analgesia for tourniquet were prolonged in the dexmedetomidine and l...Continue Reading
