Our primary hypothesis is that the Draeger dual-sensor temperature monitoring system, used at the forehead, is sufficiently accurate compared to tympanic, bladder or esophageal temperature and oral temperature for routine clinical use during hypothermic conditions, as well as during fever.
We will include patients undergoing general anesthesia or regional anesthesia. The temperature recorded by Draeger dual-sensor monitoring system will be obtained at 5-minute interval.

The sensor will be attached to the patient's forehead with adhesive tape, and a small amount of contact gel will be applied between sensor and skin.
Esophageal temperature is measured by sensors incorporated into an esophageal stethoscope during the surgery.
Urinary bladder temperature is measured via a sensor incorporated into a Foley catheter during the surgery

The Bias Between Temperature Measured by Drager Double-sensor vs Core Temperature
Determine if the Drager double-sensor temperature monitoring system, used at the forehead is accurate compared to esophageal temperature for general anesthesia group and bladder temperature for regional anesthesia group.

Sensitivity for Detection of Hypothermia
Hypothermia is defined as a temperature \< 36 Celsius degree
Time frame: From anesthesia induction to the end of surgery
Specificity for Detection of Hypothermia
Hypothermia will be defined as a temperature \< 36 Celsius degree
Time frame: From anesthesia induction to the end of surgery
