摘　　要：目的 了解上海市医院洁净手术室空气微生物负荷情况及影响因素,为针对性的改善手术室空气质量提供依据。方法 采用沉降法和浮游法,分别对上海市4家医疗机构洁净手术室空气进行连续4年的监测,并对结果进行分析和比较。结果 本研究对2016-2019年上海市4家医疗机构洁净手术室空气监测数据进行了分析。结果发现,上海市医疗机构百级、千级、万级洁净手术室空气的平均合格率分别为82.89%、91.35%以及95.83%。浮游法采样得到的细菌菌落总数大于沉降法,两种方法测得数据相关性弱,两方法合格率比较差异无统计学意义。通过Logistic回归分析发现,与洁净手术室空气监测合格的相关因素有采样的季度、医院和手术室洁净级别,而采样的年份、方法和区域对结果影响比较差异无统计学意义。结论 上海市医疗机构洁净手术室空气监测合格率受到采样的季度、医院和手术室洁净级别的影响,受采样方法影响较小。OBJECTIVE To understand the status of airborne microbial load in cleaning operating rooms of some hospitals in Shanghai and analyze the influencing factors so as to take targeted measures to improve the air quality of the operating rooms. METHODS The air in the clean operating rooms of 4 medical institutions in Shanghai was monitored by sedimentation method and floating method for 4 consecutive years, and the result of the monitoring was observed and compared. RESULTS From 2016 to 2019, the monitoring data of the air in the clean operating rooms of 4 medical institutions in Shanghai were analyzed, the result showed that the average qualified rate of the air was 82.89% in the Class 100 clean operating rooms, 91.35% in the Class 1000 clean operating rooms, 95.83% in the Class 10000 clean operating rooms. The total colony counts of bacteria that were sampled by sedimentation method were greater than those of bacteria that were sampled by the floating method, the data that were obtained by the two methods were weakly correlated, and there was no significant difference in the qualified rate between the two methods. Logistic regression analysis showed that the qualified air of the clean operating rooms was associated with the sampling season, hospital and cleanliness classification of operating rooms, however, there was no significant difference in the impact on the result among the sampling year, methods and regions. CONCLUSION The qualified rate of monitoring of the air in the clean operating rooms is affected by the season of sampling, hospital and cleanliness classification of operating room but is less affected by the sampling method.
