The rectal-axillary temperature difference (R-A) was measured in the morning, at midday, and in the afternoon on 1,519 occasions in 1,149 children from birth to 5 years old. Of these, 302 children were febrile (rectal temperature > or = 38 degrees C) and 847 were afebrile. A wide range in R-A was found for each individual in both groups. The magnitude of this difference was not associated with sex or age. In febrile children, the R-A was significantly greater (P < .0001) at the apparent onset of fever (1.04 +/- 0.25 degrees C) than later, when fever had been present for at least two hours (0.53 +/- 0.22 degrees C). These findings indicate that it is impossible to find a standard number by which to convert axillary to rectal temperature or vice versa. Furthermore axillary temperature may be relatively low or even "normal" despite an elevated rectal temperature at the onset of fever.
对1149名从出生到5岁的儿童进行了1519次测量，分别在早晨、中午和下午测量直肠-腋窝温差（R-A）。其中，302名儿童发热（直肠温度≥38摄氏度），847名儿童不发热。两组中每个个体的R-A范围都很广。这种差异的大小与性别或年龄无关。在发热儿童中，发热明显开始时的R-A（1.04±0.25摄氏度）显著高于发热至少两小时后的R-A（0.53±0.22摄氏度）（P<0.0001）。这些发现表明，不可能找到一个标准数值来将腋窝温度转换为直肠温度，反之亦然。此外，在发热开始时，尽管直肠温度升高，但腋窝温度可能相对较低甚至“正常”。
