Rectal and axillary temperatures were measured simultaneously in 83 children using three different thermometer devices providing 166 pairs of results. In the first series consisting of 22 febrile children (44 measurements) and 20 afebrile children (40 measurements), the rectal mercury measurement was compared to an axillary mercury and axillary Tempa-DOT thermometer. The axillary mercury had sensitivity of 14/22 (64%) and specificity of 20/20 (100%) while the Tempa-DOT had sensitivity of 15/22 (68%) and specificity of 19/20 (95%). In the second series comprising 21 febrile children (42 measurements) and 20 afebrile children (40 measurements) the axillary mercury had sensitivity of 11/21 (52%) and specificity of 20/20 (100%) while the electronic thermometer had sensitivity of 10/21 (48%) and specificity of 20/20 (100%). Regardless of the thermometer used, the axilla is a poor alternative to rectal measurements in the diagnosis of fever.
Mercury-free thermometers, when used in the axilla are as poor alternatives to rectal measurements as mercury-in-glass thermometers.
使用三种不同的温度计设备对83名儿童同时测量直肠温度和腋窝温度，共得到166组结果。在第一个系列中，包括22名发热儿童（44次测量）和20名不发热儿童（40次测量），将直肠水银温度计测量结果与腋窝水银温度计和腋窝Tempa-DOT温度计的测量结果进行比较。腋窝水银温度计的敏感度为14/22（64%），特异度为20/20（100%）；而Tempa-DOT温度计的敏感度为15/22（68%），特异度为19/20（95%）。在第二个系列中，包括21名发热儿童（42次测量）和20名不发热儿童（40次测量），腋窝水银温度计的敏感度为11/21（52%），特异度为20/20（100%）；而电子温度计的敏感度为10/21（48%），特异度为20/20（100%）。无论使用哪种温度计，在诊断发热时，腋窝测量都不是直肠测量的良好替代方法。
无汞温度计用于腋窝测量时，与玻璃水银温度计一样，都不是直肠测量的良好替代方法。
