Brief Summary

In general, 50-90% of patients undergoing surgery under general anesthesia are known to develop hypothermia during surgery. Due to hypothermia during surgery, the patient may cause coagulation disorders, wound infections, increased ventricular tachycardia, prolonged anesthesia drug effects, and electrification, resulting in delayed recovery after surgery, extended recovery room exit, and extended hospital stay. Therefore, unless intentional hypothermia is needed, active body temperature management during surgery is necessary. Pulmonary artery, distal esophagus, tympanic membrane, nasopharynx, oral cavity, axillary cavity, rectum, and bladder can be measured. The most accurate method for measuring deep body temperature in general anesthesia is esophageal body temperature, nasopharyngeal body temperature, It is known as tympanic body temperature. 3,4 However, the tympanic body temperature has the disadvantage that it cannot be continuously measured. Considering these points, esophageal thermometers that can be continuously measured in patients with general anesthesia and have few side effects are commonly used. The esophageal thermometer is usually inserted through the oral cavity. When the supraglottic airway device is inserted, the space in the oral cavity is filled with the supraglottic airway device, making it difficult to mount the esophageal thermometer. However, most second-generation supraglottic airway devices have gastric lumens, and gastric lumens are connected to the esophagus, allowing esophageal thermometers to be mounted through this space. Since the esophageal temperature probe is inserted in all general anesthesia patients using the supraglottic airway device in this application, the body temperature measured by the temporal artery at the same time is how accurate the body temperature measured at this time is as a reference value using the tympanic membrane. I would like to analyze the transient comparison. We will also analyze whether the esophageal thermometer mounted through the gastric lumen of the supraglottic airway device reflects the rapidly decreasing body temperature change when the pneumatic tourniquet is decompressed.
