Rectal thermometry (RT) is considered the gold standard for measuring temperature in newborns, despite increasing use of temporal artery thermometry (TT) and axillary thermometry (AT) methods. Few prospective studies compare RT, TT, and AT in a newborn nursery setting. To determine the accuracy and reliability of these methods, we enrolled 205 healthy, full-term newborns. TT displayed higher mean temperatures than RT by 0.25 °F (standard error [SE] = 0.04, < .001). AT and RT measurements did not significantly differ, with their means differing only by 0.02 °F (SE = 0.04, = .87). For reliability, RT measurements differed by 0.45 °F (SE = 0.03) in either direction of the models' predicted mean for each subject. AT and TT measurements varied much less from their predicted means 0.32 °F (SE = 0.02) and 0.34 °F (SE = 0.02), respectively (both < .001). Assuming mean RT is correct, TT is less accurate than AT. RT showed poor reliability between measurements. AT is an accurate and reliable method of temperature screening in healthy neonates.
直肠测温（RT）被认为是测量新生儿体温的金标准，尽管颞动脉测温（TT）和腋窝测温（AT）的方法越来越普及。很少有前瞻性研究在新生儿病房环境中比较 RT、TT 和 AT。为了确定这些方法的准确性和可靠性，我们招募了 205 名健康的足月新生儿。TT 的平均温度比 RT 高 0.25°F（标准误差 [SE] = 0.04，<0.001）。AT 和 RT 测量值没有显著差异，它们的平均值仅相差 0.02°F（SE = 0.04，=0.87）。对于可靠性，RT 测量值在模型预测的每个受试者平均值的任一侧方向上相差 0.45°F（SE = 0.03）。AT 和 TT 测量值与预测平均值的偏差小得多，分别为 0.32°F（SE = 0.02）和 0.34°F（SE = 0.02）（均<0.001）。假设平均 RT 是正确的，TT 比 AT 准确性低。RT 之间的测量值可靠性较差。AT 是健康新生儿体温筛查的一种准确可靠的方法。
