IRTI 检测AURI 患者体温的临床研究

Infrared thermal imaging for monitoring temperature in fever patients with acute upper respiratory infection

摘要:

目的 以水银温度计腋下测温值作为标准对照，探究红外热成像（IRTI）测量急性上呼吸道感染（AURI）发热患者额部温度的准确性。方法 对急诊71 例发热型AURI 患者同时使用水银温度计和IRTI 测温，比较分析两种测温方法的差异。结果 温度定量分析显示：发热型AURI 患者腋下温度为（38.45±0.66）℃，IRTI 测量额部最低温为（36.30±1.08）℃，最高温度为（38.66±0.68）℃，平均温度为（37.57±0.76）℃ ；腋下温度与额部最低温及平均温比较，差异有统计学意义（P <0.05）；腋下温度与最高温比较，差异无统计学意义（P >0.05），腋下温度与额部最高温呈正相关（P <0.05）。结论 IRTI 能够通过检测额部最高温度替代水银温度计测量AURI 发热患者。

Abstract: Objective To investigate the accuracy of infrared thermal imaging (IRTI) by comparing the forehead temperature of the fever patients with acute upper respiratory infection (AURI) detected by IRTI with the armpit temperature of the patients by mercury thermometers. Methods The body temperature of 71 fever patients with AURI in the Emergency Room was simutaneously detected by mercury thermometers (armpit temperature) and IRTI(forehead temperature), and then compared. Results The quantitative analysis showed that the armpit temperature of the fever patients was (38.45 ± 0.66)℃ ; and the lowest forehead temperature of the patients was (36.30 ± 1.08) ℃ ,the average forehead temperature was (37.57 ± 0.76) ℃ , the highest forehead temperature was (38.66 ± 0.68) ℃ using the IRTI. There were statistical differences between the axillary temperature and the lowest and average forehead temperature of the patients (P < 0.05). However, there was no significant difference between the axillary temperature and the highest forehead temperature (P > 0.05) and they were positively correlated (P <0.05). Conclusions IRTI can replace mercury thermometer to detect the body temperature of the fever patients with AURI by measuring the highest forehead temperature.
