Rapid and Accurate Measurement of Body Temperature in Dense Population During Coronavirus Disease 2019 Pandemic/ 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

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 27th to February 8th, 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 between 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 (P0 05);the difference between the temperatures of forehead and inner side of forearm measured by the blue thermometer was statistically significant (P0 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 or 11-25℃, 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
