spinal anesthesia is a widely used technique for both elective and emergency surgeries. Shivering is one of the most commonly recognized complications of the central neuraxial blockade because of impairment of thermoregulatory control, reported in 40%-70% of the patients undergoing surgery under spinal anaesthesia. Post-anesthetic shivering is defined as an involuntary,spontaneous,rhythmic oscillating muscle hyperactivity that increases metabolic heat production up to 600% after anesthesia. Shivering during neuraxial anesthesia is a common issue that could have possibly adverse impacts, for example, increased oxygen consumption, carbon dioxide production, lung ventilation and cardiac work, as well as causing diminished mixed venous oxygen saturation. Spinal anesthesia impedes the thermoregulatory system by restraining tonic vasoconstriction which assumes significant role in the regulation of temperature
