We compared an infrared temporal artery thermometer with our clinical standard axillary thermometer for temperature measurements in neonatal patients. We measured temporal artery (T), axillary (T, clinical standard), and rectal (T, gold standard) temperatures of 49 infants. The difference between T and T was compared with that between T and T, and the data were analyzed based on bed type and postmenstrual age. The mean T, T, and T were 37.16 (SD 0.36) °C, 36.61 (SD 0.30) °C, and 36.82 (SD 0.30) °C, respectively. The measurements by these methods were all significantly different. The mean T-T was 0.21 (SD 0.26) °C, and the mean T-T was -0.34 (SD 0.37) °C, indicating that T was closer to T than was T ( < 0.0001). T agreed more closely with T for infants in cribs than for those in incubators. Adjusting for bed type and body weight, with each week of postmenstrual age, the discrepancy between T-T and T-T decreased by 0.005°C ( = 0.034). Compared with the gold standard, T, T is not more accurate than T. The temporal artery thermometer was less accurate for infants in incubators than for infants in cribs. The accuracy of temporal artery temperature increased with postmenstrual age.
我们将一款红外颞动脉体温计与我们用于新生儿患者体温测量的临床标准腋温计进行了比较。我们测量了49名婴儿的颞动脉温度（T）、腋温（T，临床标准）和直肠温度（T，金标准）。比较了T与T之间的差值以及T与T之间的差值，并根据床型和孕龄对数据进行了分析。T、T和T的平均温度分别为37.16（标准差0.36）℃、36.61（标准差0.30）℃和36.82（标准差0.30）℃。这些方法所测结果均存在显著差异。T - T的平均值为0.21（标准差0.2）℃，T - T的平均值为 - 0.34（标准差0.37）℃，这表明T比T更接近T（P < 0.0001）。对于婴儿床中的婴儿，T与T的一致性比保温箱中的婴儿更高。在调整床型和体重后，随着孕龄每增加一周，T - T与T - T之间的差异减小0.005℃（P = 0.034）。与金标准T相比，T并不比T更准确。颞动脉体温计对于保温箱中的婴儿不如对婴儿床中的婴儿准确。颞动脉温度的准确性随孕龄增加而提高。
