摘　　要：目的通过对北京市救护车污染状况、污染菌种的分析,研究探讨快速、有效、规范的救护车的消毒方法及卫生学监测标准。方法将164辆急救车分为4组,紫外线组、臭氧组、二氧化氯消毒剂组为3个试验组,清水组为对照组;每次急救车使用后及清洗消毒后对物体表面采样,并进行细菌培养计数及细菌鉴定。结果对照组、紫外线组、臭氧组及二氧化氯消毒剂组清洗消毒后菌落数分别是0.68、0.56、0.24、0.36 CFU/m2,均能达到消毒技术管理规范要求,符合Ⅲ类环境物体表面菌落总数≤10 CFU/m2范围,杀菌率分别为71.5%、82.9%、87.1%及82.1%,二氧化氯消毒剂擦拭的消毒效果明显好于对照组,差异有统计学意义(P<0.05),紫外线和臭氧的消毒效果与对照比较,差异无统计学意义。结论二氧化氯消毒剂擦拭方法快速、有效,适用于急救车内壁及院外急救设备的卫生学监测标准。OBJECTIVE To explore a rapid,effective and normative disinfection method and hygiene monitoring standard by analyzing ambulance pollution status and bacteria species.METHODS A total of 164 ambulances were divided into 4 groups,namely UV group,Ozone group,chlorine dioxide disinfectant group was set as experimental group and pure water group as control group.Every time after the use of ambulance and disinfection,the surfaces of ambulances were sampled,bacterial culture counts and the bacterial identification were performed.RESULTS After being disinfected,the colonies of 4 different methods were 0.68,0.56,0.24 and 0.36 CFU/m2,respectively,which met the requirement of management regulation and the No.3 environmental standard on the total number of surface colonies（≤10 CFU/m^2）.The sterilization rates were 71.5%,82.9%,87.1% and 82.1%,respectively.By pairwise comparison,the effect of chlorine dioxide aerosols was significantly better than that of control group（P〈0.05）,and there were no statistically significant difference between the effects of UV and Ozone with the control group（P〉0.05）.CONCLUSION Chlorine dioxide disinfectant method is fast and effective,and is suitable for the application in hygiene monitoring standard of out-of-hospital first aid and the inner wall of the ambulances.
