新型冠状病毒肺炎流行期间密集人群体温快速精准测量方法研究

Rapid and accurate measurement of body temperature in dense population during coronavirus disease 2019 pandemic

目的研究新型冠状病毒肺炎流行期间密集人群体温快速精准测量方法。方法2020年1月27日-2月8日分别在4~6℃(n=152)、7~10℃(n=103)、11~25℃(n=209)环境下,对受检者分别使用2种非接触式电子体温枪(分别简称为"蓝枪"和"红枪")测量额部、前臂内侧、颈部体温,同时以水银体温计测量的腋下体温为金标准,比较测量结果的差异。结果在7~10℃环境下,蓝枪额部、红枪额部、水银体温计体温值差异无统计学意义(P>0.05);蓝枪额部、前臂内侧、颈部体温值差异无统计学意义(P>0.05);红枪额部与前臂内侧体温值差异无统计学意义(P>0.05),红枪额部与颈部体温值差异有统计学意义(P<0.05)。在11~25℃环境下,蓝枪额部、红枪额部、水银体温计体温值差异无统计学意义(P>0.05);蓝枪额部与前臂内侧体温值差异有统计学意义(P<0.05),蓝枪额部与颈部体温值差异无统计学意义(P>0.05);红枪额部、前臂内侧、颈部的体温值差异无统计学意义(P>0.05)。按照说明书,蓝枪可允许的波动范围为0.3℃,红枪可允许的波动范围为0.2℃,2种产品不同测量部位的测量均数差值均在可允许的波动范围内,因此,7~25℃环境下体温值差异无临床意义。在4~6℃环境下,蓝枪与红枪体温值测出率分别为2.2%和19.1%。结论在7~10、11~25℃环境下,上述2种非接触式体温枪测量不同部位的体温与金标准水银体温计测量体温值比较差异均无临床意义,可推广使用非接触式电子体温枪进行快速体温筛查,但为保持体温测量人员与受检者之间的最大距离,减少交叉感染风险,推荐选择前臂内侧进行体温测量。在4~6℃环境下,上述2种体温枪测出率均低,不能用于快速体温筛查。

Objective To study the method of rapid and accurate measurement of body temperature in dense population during the coronavirus disease 2019 pandemic.Methods From January 27 th to February 8 th,2020,subjects were respectively measured with two kinds of non-contact infrared thermometers(blue thermometer and red one)to measure the temperature of forehead,neck,and inner side of forearm under the conditions of 4–6℃(n=152),7–10℃(n=103),and 11–25℃(n=209),while the temperature of axillary was measured with mercury thermometer under the same conditions.Taking the mercury thermometer temperature as the gold standard,the measurement results with noncontact infrared thermometers were compared.Results At 7–10℃,there was no statistical difference among the forehead temperatures measured by the two non-contact infrared thermometers and the axillary temperature(P>0.05);there was no difference among the temperature measured by blue thermometer on forehead,neck,and inner side of forearm(P>0.05);no difference was found between the temperature measured by the red thermometer on forehead and inner side of forearm(P>0.05),while there was statistical difference between the temperatures measured by the red thermometer on forehead and neck(P<0.05).Under the environment of 11-25℃,there was no statistical difference among the forehead temperatures measured by the two infrared thermometers and the axillary temperature(P>0.05);the difference between the temperatures of forehead and inner side of forearm measured by the blue thermometer was statistically significant(P<0.05),while no difference appeared between the forehead and neck temperatures measured by the blue thermometer(P>0.05);there was no statistical difference among the temperatures of three body regions mentioned above measured by the red thermometer(P>0.05).According to the manual,the allowable fluctuation range of the blue thermometer was 0.3℃,and that of the red one was 0.2℃.The mean differences in measured values between different measured sites of the two products were within the allowable fluctuation range.Therefore,the differences had no clinical significance in the environment of 7–25℃.Under the environment of 4–6℃,the detection rate of blue thermometer was 2.2%and that of the red one was 19.1%.Conclusions There is no clinical difference between the temperature measured by mercury thermometer and the temperature measured by temperature guns at 7–10 or11–25℃,so temperature guns can be widely used.In order to maintain the maximum distance between the measuring and the measured persons and reduce the infection risk,it is recommended to choose the inner forearm for temperature measurement.Under the environment of ambient temperature 4–6℃,the detection rate of non-contact electronic temperature gun is low,requiring taking thermal measures for the instrument.
