The prevention of inadvertent perioperative hypothermia requires precise, reliable and practical methods of temperature measurement in both awake and anaesthetised patients. Different methods and sites of monitoring have been evaluated, but many are imprecise, unusable in awake patients, difficult to apply or too invasive, especially for minor surgery. The aim of this study was to evaluate the performance of perioperative sublingual and tympanic temperature measurement in awake and anaesthetised patients.
We enrolled 171 patients, aged 18-75 years, scheduled for surgery with duration less than 1 h under general anaesthesia. Spearman's rank correlation and Bland-Altman analysis for assessment of correlation, accuracy and precision of both methods were determined analysing 171 independent paired values at three different measurement times.
Sublingual temperatures were significantly higher than tympanic temperatures by 0.1-0.2°C. The coefficient of determination (r) of both methods was between 0.50 and 0.59, and Bland-Altman analysis revealed a bias (SD) of between -0.09 (0.21) and -0.15 (0.24)°C.
The accuracy and precision of sublingual temperature measurement were adequate for clinical use, and there was a high correlation with tympanic temperature monitoring. Sublingual temperature measurement has been demonstrated as a good and practical modality for perioperative temperature monitoring in both awake and anaesthetised patients.
为了预防术中意外低体温，需要在清醒和麻醉患者中使用精确、可靠且实用的体温测量方法。已经评估了不同的监测方法和部位，但许多方法不够精确，在清醒患者中无法使用，难以应用或过于侵入性，尤其是对于小型手术。本研究旨在评估清醒和麻醉患者术中舌下和鼓膜温度测量的性能。
我们纳入了 171 名年龄在 18-75 岁之间、预计接受全身麻醉下持续时间小于 1 小时的手术患者。通过 Spearman 等级相关分析和 Bland-Altman 分析评估两种方法的相关性、准确性和精密度，分析了三个不同测量时间的 171 个独立配对值。
舌下温度比鼓膜温度高 0.1-0.2°C。两种方法的决定系数（r）在 0.50 到 0.59 之间，Bland-Altman 分析显示偏差（SD）在-0.09（0.21）和-0.15（0.24）°C 之间。
舌下温度测量的准确性和精密度足以满足临床应用，与鼓膜温度监测有高度相关性。在清醒和麻醉患者中，舌下温度测量已被证明是一种良好且实用的围手术期体温监测方法。
