Evaluation of a New, Improved Deep Body Thermometry System
Patients can easily be subject to hypothermia in an operating room.1,2 Thus, monitoring a patient’s body temperature is one of the most important tasks during anesthesia. Although the esophageal and the tympanic membrane thermometry are the most reliable sites for this purpose, their thermometry may be associated with trauma.1,2 In contrast, a newly developed deep body thermometry system, CTM-205™ (Terumo, Tokyo), can be used to measure body temperature by simply placing a probe on the skin surface.3 The principle of this method, originally proposed by Fox and Solman is to create a region of zero heat flow under the probe.4 We evaluated the accuracy and precision of this system during major surgery, using pulmonary arterial blood temperature as a standard.
