Accuracy of Temporal Artery Thermometry as an Indicator of Core Body Temperature in Patients Receiving General Anesthesia.

Purpose: To evaluate the agreement of temporal artery temperature (Tat) with esophageal temperature (Tes) and oral temperature (Tor), and explore potential factors associated with the level of agreement between the thermometry methods in different clinical settings.

Design: A prospective repeated measures (induction, emergence, and postanesthesia care unit) design was used.

Methods: Temperature data were collected for 54 patients receiving general anesthesia.
