In anesthesia, monitoring of core body temperature is one of important factors. Measurement of temperature using a pulmonary artery catheter is representative one of core temperature measurements. The core temperature by a pulmonary artery catheter is compared with the tracheal temperature by an endotracheal tube with thermometer. This study was designed to confirm the accuracy of the endotracheal tube thermometer.

Comparison of tracheal temperature versus pulmonary artery temperature
Timeframe: Tracheal temperature and pulmonary arterial temperature are measured every 5 minutes for 1 hour after induction of general anesthesia.
