To compare measurements made with four infrared tympanic thermometers (Genius, Thermopit, Quickthermo, and Thermoscan) with those recorded from thermocouples positioned in the contralateral ear.
Four tympanic thermometers were evaluated in 50 healthy volunteers (12 female and 38 male). Temperatures were measured, in random order, at the right tympanic membrane four times and the highest temperature was considered to be the true value measured by each thermometer. The control temperature was measured at the left tympanic membrane using Mon-a-Therm thermocouples.
The tympanic membrane temperature measured by Genius correlated best with the Mon-a-therm measurement (TM) (r = 0.74). The tympanic membrane temperatures measured by Thermopit, Quickthermo, and Thermoscan correlated moderately with TM (r = 0.56, 0.63, and 0.58, respectively). Mean differences between TM and each temperature (TG, TTP, TQ, and TTS) were -0.3, 0.73, 0.42, and -0.3 degrees C, respectively. Likewise standard deviations were 0.33, 0.37, 0.35, and 0.35.
We conclude that all but the Thermopit (TTP) are similarly useful for the management of patients during anaesthesia.
比较四种红外鼓膜温度计（Genius、Thermopit、Quickthermo和Thermoscan）的测量结果与对侧耳中热电偶记录的测量结果。
对50名健康志愿者（12名女性和38名男性）的四种鼓膜温度计进行评估。以随机顺序在右鼓膜测量四次温度，每种温度计测量的最高温度被视为真实值。使用Mon-a-Therm热电偶在左鼓膜测量对照温度。
Genius测量的鼓膜温度与Mon-a-therm测量值（TM）相关性最佳（r = 0.74）。Thermopit、Quickthermo和Thermoscan测量的鼓膜温度与TM中度相关（分别为r = 0.56、0.63和0.58）。TM与每种温度（TG、TTP、TQ和TTS）之间的平均差异分别为-0.3、0.73、0.42和-0.3摄氏度。同样，标准差分别为0.33、0.37、0.35和0.35。
我们得出结论，除了Thermopit（TTP）之外，所有温度计在麻醉期间对患者的管理同样有用。
