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172辆急救车分为4纰，紫外线组、臭氧组、二氧化氯气溶胶消毒组为3个实验组为，清水组为对照组。每次急救车使用后及清洗消毒后对空气采样，并进行细菌培养计数及细菌鉴定。结果4种方法均能达到消毒技术管理规范要求，符合Ⅲ类环境空气细菌菌落总数≤500cfu／m^3范周。紫外线和二氧化氯气溶胶的消毒效果，明显好于对照组（均P〈0．05），臭氧的消毒效果与对照组比较无显著性差异（P〉0．05）。结论紫外线和二氧化氯气溶胶消毒方法快速、有效，适用于急救车等院外急救设备的卫生学监测标准。Objective To compare the effects of different disinfection methods inside ambulance. Methods 172 ambulances were randomly divided into 4 groups： ultraviolet （UV） ray group, ozone group, chlorine dioxide aerosol group （as experimental groups）, and control group in which the vehicles were cleaned only with water. Upon completion of disinfection after the ambulance was used each time, air samples were collected to undergo bacterial culture. Results All four methods passed the disinfection technology management specification and met the third class range of total number of bacterial （〈500 cfu/m^3）. The disinfection effects rates of the UV and chlorine dioxide aerosols methods were both higher than that of the control group （ both P〈0.05）, while the ozone group demonstrated no significant difference than the control group （P〉0.05）. Conclusion UV and chlorine dioxide aerosols methods are considered as fast and effective methods, and their results keep in line with the hygiene monitoring standards of pre-hospital emergency equipment.
