摘　　要：目的了解新冠疫情常态化防控期间日常救护车医疗舱内物体表面污染状况,为进一步规范、改进制定新型冠状肺炎疫情常态化防控下救护车医疗舱日常消毒方法提供依据。方法2020年12月起随机对上海市医疗急救中心担任急救任务的日常救护车医疗舱内担架床、座椅、医疗舱物体表面及常用医疗设备表面4个大类进行菌落数规范采样及送检,获得菌落数定量数据。依照《医院消毒卫生标准》中物体表面菌落总数卫生标准对结果进行合格判断。结果日常救护车医疗舱内担架床、座椅、医疗舱物体表面及常用医疗设备表面4个大类中22个类别的274个位点菌落数值总体合格率为86.86%,其中担架床菌落数值总体合格率显著低于座椅、医疗舱物体表面及常用医疗设备表面菌落数合格率,差异有统计学意义(P<0.05);担架床保险带的单个点位检出菌落数最多,高达1112 cfu/cm^(2);担架床肩部、腰部及脚部不同部位保险带菌落数相比差异具有统计学意义(P<0.05)。结论新冠疫情常态化防控期间急救人员对救护车医疗舱日常消毒工作中,需重点关注担架床及担架床保险带的清洁消毒管理及急救人员消毒规范操作。Objective To explore the surface pollution of objects in the medical cabin of the daily ambulance during normalized prevention and control of the new coronavirus pneumonia epidemic,in order to provide a basis for further standardizing and improving the daily disinfection of the ambulance under the specific situation.Methods Since December 2020,the number of colonies was determined in samples collected from stretcher,seats,surfaces of medical cabin objects,and surfaces of commonly used medical equipment in the medical cabin of the daily ambulance of Shanghai Medical Emergency Center.Quantitative data on the number of colonies were obtained.The results were judged according to the health standards for the total number of colonies on the surface of the object in the"Hospital Disinfection and Hygiene Standards".Results The overall qualification rate of colonies about 274 sites in 22 categories of stretchers,seats,surfaces of medical cabin objects,and surfaces of commonly used medical equipment was 86.86%.Among them,the overall qualification rate of colonies from stretcher was significantly lower than that of the surface of the seat,medical cabin objects,and the surface of commonly used medical equipment,and the differences were significant statistically(P<0.05).The single point of the safety belt of stretcher had the highest number of colonies(1112 cfu/cm^(2)),and there were statistically significant differences among the safety belt in different parts of the stretcher(shoulder,waist,and feet),P<0.05.Conclusion During normalized prevention and control of the new coronavirus pneumonia epidemic,emergency personnel should pay attention to the cleaning and disinfection management of stretcher and safety belts of stretcher and the standard operation in the daily disinfection of ambulance.
