Comparison between General and Spinal Anesthesia for Changes of Core and Peripheral Body Temperature in Leg Surgery

Abstract

The most common in traoperative temperature disorder during surgery is unintended hypothermia, it’s prevalence is50% to 90% [1-4]. Hypothermia is the result of combining general anesthesia and exposure to the cold operation rooms. In general anesthesia, the threshold required for vasoconstriction and shivering is decreased by 2-3°C. Thelargest primary cause of hypothermia in most patients is the redistribution of body temperature from center to the environment [5-7]. Neuraxial anesthesia also disturbs score and peripheral thermoregulation control, which is accompanied by hypothermia [8,9].
