[0002] Perioperative hypothermia refers to a state in which the patient's body temperature drops below normal during surgery. Normal body temperature usually refers to 36.5~37.5℃, while hypothermia refers to body temperature below this range. Medical perioperative hypothermia is an important clinical issue, which may have many effects on patients. Hypothermia can inhibit sinus node function, slow conduction, and lead to a decrease in heart rate and cardiac output. At the same time, it may also increase the sensitivity of myocardial cells to calcium ions, making ventricular fibrillation more likely to occur. Severe hypothermia can lead to increased peripheral vascular resistance, ventricular arrhythmias and myocardial depression. In order to prevent this from happening, a dual warming device can be used. The medical perioperative hypothermia dual warming device is a warming device designed specifically for patients during surgery. It aims to prevent and treat perioperative hypothermia.
