摘要

人類皮膚表面會釋放出紅外線，其能量經由轉換可以測知其表面溫度；而鼓膜位於外耳道深部，經由蒸發、對流、傳導和紅外線的散發所散失的能量較少，並且有豐富的血流供應，而被認為可以作為測量體溫變化的適當部位。我們以紅外線測溫器測量65名住院病患的單側或兩側鼓膜溫度，發現它並不受室溫的影響，而與口溫或肛溫有很多的正相關（r＝0.919），因而認為以紅外線對鼓膜溫度之測量可以作為中心體溫的測定。

Human skin emits infrared energy that can be transformed to temperature. The tympanic membrane which is deep in the external auditory canal has a rich blood supply and has less chance of energy loss by evaporation, convection, conduction and infrared emission. The tympanic membrane is thus thought to be an appropriate site for measuring body core temperature.
We used an infrared thermometer to measure the tympanic membrane temperature of 65 in-patients. There was a good correlation between the tympanic membrane temperature and the oral temperature (r＝0.919), and the tympanic membrane temperature did not change by the effect of room temperature. We also studied how acute otitis media would affect the tympanic membrane temperature, and failed to find a significant difference between the infected and uninfected ears. So the tympanic thermometer cannot be a useful ancillary tool for diagnosing acute otitis media. It is an expeditious, non-invasive and accurate thermome ter for measurement of the core temperature.
