We wished to determine the accuracy of thermometers used to measure temperature in newborn infants. We measured the temperature of a water bath with three types of thermometer set at 0.5°C increments between 32.5°C and 38.5°C and compared the values to a control. We recorded the time to display steady-state temperature. The Microlife thermometer most closely approximated control temperature (mean difference <0.1°C (SD<0.1°C)) and displayed a reading in a mean time of 29 s (SD 2 s). Used in 'predictive' (default) mode, the Welch Allyn SureTemp Plus 692 thermometer differed from the control by a mean of 0.6°C (SD 0.3°C), displaying a temperature at 15 s (SD 3 s). This device consistently overestimated temperature. In 'continuous' mode, the mean difference was <0.1°C (SD<0.1°C) at 5 min. The Phillips probe differed from the control by a mean of 0.4°C (SD 0.2°C). Thermometers used to measure temperature in newborn infants may underestimate hypothermia. A prospective study in newborn infants is needed.
我们旨在确定用于测量新生儿体温的温度计的准确性。我们测量了三种类型的温度计在 32.5°C 至 38.5°C 之间以 0.5°C 为增量设置的水浴温度，并将测量值与对照值进行比较。我们记录了达到稳定温度的时间。Microlife 温度计最接近对照温度（平均差值<0.1°C（SD<0.1°C）），平均显示读数时间为 29 秒（SD 2 秒）。在“预测”（默认）模式下，Welch Allyn SureTemp Plus 692 温度计与对照值相差 0.6°C（SD 0.3°C），平均 15 秒（SD 3 秒）显示温度。该设备始终高估温度。在“连续”模式下，5 分钟时平均差值<0.1°C（SD<0.1°C）。Phillips 探头与对照值相差 0.4°C（SD 0.2°C）。用于测量新生儿体温的温度计可能会低估低体温。需要对新生儿进行前瞻性研究。
