Shivering is one of the most common complications of neuraxial blockade. Some patients find shivering sensation worse than surgical pain. Therefore, both prevention and treatment of established shivering should be regarded as clinically relevant intervention in the perioperative period.
AIM: The present study was done to evaluate and compare the efficacy, hemodynamics and adverse effects of Magnesium sulphate and Dexmedetomidine when used for control of intra operative shivering during neuraxial anaesthesia.
Materials And Method: A prospective double blind study was conducted by enrolling 253 patients undergoing lower abdominal and lower limb surgeries under neuraxial anesthesia in age group 20 to 60year with written informed consent. Patients developing intraop shivering were randomly divided into two groups Group A (50patients)- received Magnesium sulphate 50mg/kg IV bolus and Group B (50patients)- received Dexmedetomidine 0.5microgram/kg IV. Study was done until 50 patients were studied by both the study groups.
Results: The study shows a highly statistically significant difference (P value 0.001) between both groups in terms of heart rate, systolic blood pressure, diastolic blood pressure, core body temperature, time to disappearance of shivering and mean respiratory rate between both the groups.
Conclusion: In the above study Dexmedetomidine was more efficacious than Magnesium sulphate interms of maintaining hemodynamics and control of shivering in neuraxial anaesthesia.
