A comparison of parallel measurements of body temperature with infrared tympanic thermometry (First Temp 2000A) in both ears and with rectal mercury thermometer were performed in 100 patients with stroke (n = 60) or spinal cord injury (n = 40). Agreement between the two methods of temperature determination was assessed by calculating limits of agreement within which 95% (+/- 2 SD) of the individual differences would fall. Ear temperature was on average 0.3 +/- 1.0 (2 SD) degrees C above rectal temperature (p < 0.01). The upper and lower limits of agreement between the two methods were -0.7 degrees C and +1.3 degrees C, respectively. Mean difference between ear temperature in right and left ear was 0.0 +/- 0.7 (2 SD) degrees C. According to these results tympanic membrane temperature measured with First Temp 2000A appears to give clinical significant erroneous readings, and should be used with caution.
对100例中风患者（n = 60）或脊髓损伤患者（n = 40）使用红外鼓膜温度计（First Temp 2000A）对双耳进行体温平行测量，并与直肠水银温度计进行比较。通过计算个体差异95%（±2标准差）所在的一致性界限来评估两种体温测定方法之间的一致性。耳部温度平均比直肠温度高0.3±1.0（2标准差）摄氏度（p < 0.01）。两种方法之间的一致性上限和下限分别为-0.7摄氏度和+1.3摄氏度。左右耳耳部温度的平均差异为0.0±0.7（2标准差）摄氏度。根据这些结果，使用First Temp 2000A测量的鼓膜温度似乎会给出具有临床意义的错误读数，应谨慎使用。
