Reliability of Tracheal Temperature as a Measurement of Core Body Temperature During Cardiac Surgery Using Cardiopulmonary Bypass.

ABSTRACT: Background: To compare tracheal temperature (T_ET) with nasopharyngeal temperature (T_NP) in patients undergoing cardiac surgery using cardiopulmonary bypass (CPB). Methods: T_ET was measured using a thermistor in the cuff of an endotracheal tube and T_NP was monitored using an esophageal stethoscope. Depending on the management of the CPB strategy, the operation was divided into four periods (pre-CPB, cooling, rewarming, and post-CPB). A Bland-Altman analysis was carried out to compare T_ET with T_NP in each period. The concordance correlation coefficient for repeated measures analysis and various time lags was used to validate the time lag maximizing the concordance correlation coefficient between the two methods.
