摘要
Background: An ear-fitting thermometer probe “NIPRO CE THERMO?” (Nipro Corporation, Osaka, Japan, new CE thermo) for both ears was newly developed in 2017. Since new release, we have never investigated about an accuracy of the new CE thermo. In this time, the accuracy of the CE thermo was investigated. Methods: The correlation between the tympanic membrane temperature, measured using the new CE thermo, and the esophageal temperature of 30 patients (right ear: 16 patients, left ear: 14 patients) was measured in the prospective observational study. Results: A good correlation (r = 0.721) and no measurement error (within 1?C in mean ± 2SD) between the two temperatures were observed using Bland-Altman analysis. The correlation and measurement error for each ear yielded the same results. Conclusion: The tympanic membrane temperature, measured using the new CE thermo, showed good correlation with the esophageal temperature and could be used as a central temperature in the perioperative period.
