Intraoperative Body Temperature Measurement Using Infrared Camera: Comparison With Esophageal, and Skin Temperatures

"A method of monitoring body temperature during surgery is to measure esophageal temperature using a catheter. Although this method is known as a method to accurately measure core temperature, it is not recommended for local anesthesia patients and requires an invasive procedure that can be used to monitor body temperature non-invasive as it may feel uncomfortable during placement and maintenance management. Various methods have been developed to measure body temperature noninvasive, such as in the mouth, armpits, skin surfaces, and aural canals. However, developed methods can also cause discomfort to patients in that they attach sensors to their skin. In this study, we use the esophageal temperature measurement method, the skin contact temperature measurement method, and the IR contactless temperature measurement method to simultaneously measure body temperature and to compare the accuracy of body temperature measurement according to each method."
