目的：本研究的目的是比较使用一种新的无创连续零热流温度测量系统获得的深部体温与使用传统方法获得的核心温度。设计：一项前瞻性观察性研究。设置：一所大学医院的手术室。参与者：该研究包括15名接受下肢血管手术的患者和15名接受心肺功能衰竭的心脏手术的患者。bypass.Interventions:测量和主要结果：使用新的温度测量系统（SpotOn; 3 M，圣保罗，MN）测量前额上的体温，并在血管手术期间（n = 15）和心脏手术期间（n = 15）在鼻咽和肺动脉中使用常规方法测量食道中的体温。使用Bland-Altman随机效应方法对重复测量进行评估。SpotOn和之间的平均差异为+0.08 ℃（95%一致性限值-0.25至+0.40 ℃）。在心脏手术期间，在非体外循环期间，SpotOn和肺动脉温度之间的平均差异为-0.05 ℃（95%一致性限值-0.56至+0.47 ℃）。在整个心脏手术过程中（CPB和非CPB），SpotOn和鼻咽温度之间的平均差异为-0.12 ℃（95%一致性限值为-0.94至+0.71 ℃）。在低于约32摄氏度的低温下检测到SpotOn和鼻咽温度之间的协议差。结论：根据这项初步研究，使用零热通量系统测量的深部体温与下肢血管和心脏手术期间的标准核心温度非常一致。然而，在低于32 ℃的低温期间，一致性值得怀疑。(C)2016 Elsevier Inc.

Objective: The aim of this study was to compare deep body temperature obtained using a novel noninvasive continuous zero-heat-flux temperature measurement system with core temperatures obtained using conventional methods.Design: A prospective, observational study.Setting: Operating room of a university hospital.Participants: The study comprised 15 patients undergoing vascular surgery of the lower extremities and 15 patients undergoing cardiac surgery with cardiopulmonary bypass.Interventions: Zero-heat-flux thermometry on the forehead and standard core temperature measurements.Measurements and Main Results: Body temperature was measured using a new thermometry system (SpotOn; 3M, St. Paul, MN) on the forehead and with conventional methods in the esophagus during vascular surgery (n = 15), and in the nasopharynx and pulmonary artery during cardiac surgery (n = 15). The agreement between SpotOn and the conventional methods was assessed using the Bland-Altman random-effects approach for repeated measures. The mean difference between SpotOn and the was +0.08 degrees C (95% limit of agreement-0.25 to +0.40 degrees C). During cardiac surgery, during off CPB, the mean difference between SpotOn and the pulmonary arterial temperature was-0.05 degrees C (95% limits of agreement-0.56 to +0.47 degrees C). Throughout cardiac surgery (on and off CPB), the mean difference between SpotOn and the nasopharyngeal temperature was-0.12 degrees C (95% limits of agreement-0.94 to +0.71 degrees C). Poor agreement between the SpotOn and nasopharyngeal temperatures was detected in hypothermia below approximately 32 degrees C.Conclusions: According to this preliminary study, the deep body temperature measured using the zero-heat-flux system was in good agreement with standard core temperatures during lower extremity vascular and cardiac surgery. However, agreement was questionable during hypothermia below 32 degrees C. (C) 2016 Elsevier Inc. All rights reserved.
