一种新近上市的设备使用耳探头测量体温，该耳探头检测来自鼓膜的红外辐射。它使用简单，在1-2秒钟内给出一个阅读。通过将其与使用标准电子温度计IVAC（San Diego，CA）获得的直肠（n = 65）或口腔（n = 48）温度进行比较，在一组1个月至10岁的儿童中评估其准确性。两次读数之间的平均间隔时间为11分钟。总体而言，60例直肠温度和40例口腔温度（88.5%）使用IVAC高于使用听觉传感器。差值范围为-0.7 ° C至+2.5 ° C。红外耳探头值与直肠和口腔温度读数之间的相关性分别为0.77和0.75。因为使用听觉传感器的平均阅读低于使用IVAC的平均读数，所以听觉传感器用于检测临床上重要的发热水平的灵敏度低。直肠温度为39°C或更高的7名患者中没有一名患者，直肠温度为38°C或更高的27名患者中只有7名被听觉传感器识别为温度高于这些截止水平。类似地，三名口腔温度为39°C或更高的患者中没有一名被听觉传感器正确识别，八名口腔温度为38°C或更高的患者中只有三名被听觉传感器正确识别。作者得出结论，听觉传感器在儿科门诊环境中检测临床显著发热不令人满意。
A newly marketed device measures body temperature using an ear probe that detects infrared radiation from the tympanic membrane. It is simple to use and gives a reading in 1-2 seconds. Its accuracy was evaluated in a group of children, aged 1 month through 10 years, by comparing it with either rectal (n = 65), or oral (n = 48) temperatures obtained with a standard electronic thermometer, IVAC (San Diego, CA). The average elapsed time between readings was 11 minutes. Overall, 60 rectal and 40 oral temperatures (88.5%) were higher with IVAC than with the aural sensor. The difference ranged from -0.7°C to +2.5°C. The correlations between the infrared ear-probe values and the rectal and oral temperature readings were 0.77 and 0.75, respectively. Because the average reading using the aural sensor was lower than that using the IVAC, the sensitivity of the aural sensor for detecting clinically important levels of fever was low. None of seven patients with a rectal temperature of 39°C or more and only 7 of 27 with a rectal temperature of 38°C or more were identified by the aural sensor as having temperatures above these cutoff levels. Similarly, none of three patients with an oral temperature of 39°C or more and only three of eight with an oral temperature of 38°C or more were identified correctly by the aural sensor. The authors conclude that the aural sensor is unsatisfactory for detecting clinically significant fevers in a pediatric outpatient setting.
