目的：探讨北方冬季某医院儿科门急诊候诊厅空气消毒模式。方法使用紫外线循环风消毒后，在新疆医科大学第一附属医院儿科门急诊候诊厅进行采样：（1）人流量相同（50～99人次）下，消毒前及消毒持续1 h末、2 h 末分别采样；（2）人流量为1～49、50～99、100～150人次时持续消毒2 h 后即刻分次采样；（3）人流量相同（50～99人次）下，持续消毒1 h 后及间隔1、2 h 分别采样，观察空气细菌菌落数的变化。结果（1）在人流量相同、循环风量与房屋体积相当的情况下，消毒持续1 h 末细菌菌落数为（12．890±5．023）个／皿，消毒持续2 h 末细菌菌落数为（16．160±6．184）个／皿，差异无统计学意义（P ＝0．211）。（2）随着人流量不断增加，细菌菌落数也逐渐增长。消毒后2 h，人流量为1～49、50～99、100～150人次时细菌菌落数分别为（12．110±1．966）、（21．810±2．727）、（30．800±7．987）个／皿，不同人流量间细菌菌落数差异有统计学意义（P ＜0．05）。（3）消毒完成后，随着间隔时间延长，细菌菌落数越多。消毒完成后间隔1、2 h 细菌菌落数分别为（6．350±6．396）、（14．300±4．755）个／皿，差异有统计学意义（P ＝0．006）。结论根据季节及门诊量采取相应的消毒模式，北方冬季门诊量大且不能开窗通风，可增加消毒次数，缩短消毒间隔时间；注重患者流管理，减少人流量。

Objective To explore the air disinfection mode in diagnosis hall of pediatric hospital emergency in northern winter.Methods After ultraviolet disinfection.Sampling was conducted with the same dis-charge (50 to 99 passengers),before disinfection,and disinfection of 1 h end,2 h end ;the traffic is 1 to 49,99 to 100,50 to 150 people,and sampled immediately after 2 h continuous disinfection;with the same traffic,(50 to 99 persons),1 h,1 h and 2 h respectively were sampled after continuous disinfection. Counting the total number of bacteria colonies in the air.Results In the case of the same volume of traf-fic,circulating air volume and the volume of the housing.The number of bacteria in the end of 1 h was (12.890±5.023)per dish.The number of bacteria in the end of 2 h was (16.160±6.184)per dish.The difference was no statistically significant (P =0.211).With the increase of the flow of people,the number of bacterial colonies gradually increased.After disinfection,the number of bacteria was 1 to 49,to 50,2 to 99,and 100 to 150 (12.110±1.966)per dish,(21.810±2.727)per dish,(30.800±7.987)per dish.There was a significant difference in the number of bacterial colonies between different people (P <0.05).After disinfection,the number of bacterial colonies increased with the time interval.After disinfection,the bac-terial colonies were 1 and 2 h,respectively.(6.350±6.396)per dish (14.300±4.755)per dish.Showed sta-tistically significant (P = 0.006 ).Conclusion Disinfection mode should be shifted according to the seasonal and outpatient amounts in North winter,increase the number of disinfection,shorten the time of disinfection,monitor patient flow,and reduce traffic.
