摘要
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1h末、2h末分别采样;（2）人流量为1~49、50~99、100~150人次时持续消毒2h后即刻分次采样;（3）人流量相同（50~99人次）下,持续消毒1h后及间隔1、2h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1h末细菌菌落数为（12.890±5.023）个/皿,消毒持续2h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2h,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、2h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.
