Rectal thermometry correlates with core temperature and represents the criterion standard of measuring temperatures in young children. However, it has numerous disadvantages, and thus, an alternative method of measuring temperature with similar agreement with the core temperature as rectal thermometry is desired. A new, noninvasive temporal artery (TA) thermometer synthesizes the skin surface and ambient temperatures to produce an arterial temperature.
To examine the agreement between the TA and esophageal core thermometers, and to compare it with that between rectal and esophageal temperatures.
In the present prospective, cross-sectional agreement study, intubated surgical outpatients younger than 18 years of age had temperatures measured with esophageal and rectal probes, and rectal electronic and TA thermometers. The agreement between esophageal versus rectal and TA thermometers was analyzed by intraclass correlation coefficients and by differences between esophageal versus TA and rectal temperatures with 95% CIs. The esophageal-rectal and esophageal-TA slopes were compared by Student's t test.
In 80 enrolled children, the intraclass correlation coefficients for the esophageal probe versus rectal probe, rectal electronic thermometer and TA thermometer were 0.91, 0.95 and 0.88, respectively. The mean esophageal-rectal difference was 0.00+/-0.18 degrees C and esophageal-TA difference was 0.14+/-0.20 degrees C. Linear regression analysis of the relation between esophageal probe versus rectal probe, rectal thermometer and TA thermometer yielded slopes of 0.93, 0.94 and 0.89, respectively. The slopes were neither different from each other (P=0.70) nor from the value of 1.
The TA and esophageal thermometers agree well, and the esophageal-TA and esophageal-rectal temperature agreements are not significantly different.
直肠测温与核心体温相关，是测量幼儿体温的标准方法。然而，它存在诸多缺点，因此，人们希望找到一种与核心体温一致性与直肠测温相似的替代测温方法。一种新型的非侵入性颞动脉（TA）温度计综合皮肤表面温度和环境温度来得出动脉温度。
研究TA温度计与食管核心温度计之间的一致性，并将其与直肠温度和食管温度之间的一致性进行比较。
在这项前瞻性横断面一致性研究中，对18岁以下的插管手术门诊患者使用食管探头、直肠探头、直肠电子温度计和TA温度计测量体温。通过组内相关系数以及食管与TA温度计和直肠温度之间的差异（95%置信区间）分析食管与直肠及TA温度计之间的一致性。通过学生t检验比较食管 - 直肠和食管 - TA斜率。
在80名纳入研究的儿童中，食管探头与直肠探头、直肠电子温度计和TA温度计的组内相关系数分别为0.91、0.95和0.88。食管 - 直肠平均差值为0.00±0.18℃，食管 - TA平均差值为0.14±0.20℃。食管探头与直肠探头、直肠温度计和TA温度计之间关系的线性回归分析得出斜率分别为0.93、0.94和0.89。这些斜率彼此之间无差异（P = 0.70），也与1无差异。
TA温度计和食管温度计一致性良好，食管 - TA和食管 - 直肠温度的一致性无显著差异。
