Comparison of Intravenous Dexmedetomidine and Tramadol for Control of Shivering Under Spinal Anaesthesia. A Prospective Randomised Study

This prospective study compared intravenous dexmedetomidine and tramadol for controlling shivering during spinal anaesthesia in 70 adult patients. Primary outcomes included time for shivering resolution, with secondary outcomes covering shivering incidence, hemodynamics, adverse events, and patient satisfaction. Dexmedetomidine exhibited superior efcacy (p < 0.05), achieving quicker resolution and lower shivering incidence (15%) compared to tramadol (30%). Both drugs were well-tolerated, and patient satisfaction was higher with dexmedetomidine. Dexmedetomidine showed promise for perioperative shivering control, enhancing comfort and satisfaction.
