西安市部分手术室尘埃粒子数与浮游菌监测报告

目的了解西安市市属医院洁净手术室环境质量状况，为保障手术室洁净质量提供参考。方法采用现场采样与检测方法，对西安市 15所市属医院的洁净手术室进行空气洁净度检测与分析。结果共监测51间手术间。其中二级医院24间，三级医院27间；Ⅰ级手术室26间，Ⅲ级手术室25间。Ⅰ、Ⅲ级洁净手术室≥0.5 μm/粒径合格率分别为76.92%、80.00%，≥5 μm/粒径合格率分别为73.08%、88.00%。Ⅰ级和Ⅲ级洁净手术室尘埃粒子数合格率分别为61.54%和80.00%，经检验差异无统计意义（χ2=2.092，P＞0.05）。三级医院洁净手术室尘埃粒子数合格率为85.19%，高于二级医院的58.33%（χ2=4.600，P<0.05）。二、三级医院手术区浮游菌检测合格率分别为87.50%、92.59%，周边区合格率分别为95.83%、92.59%，二、三级医院手术区及周边区浮游菌检测合格率比较差异均无统计学意义（均P＞0.05）。结论西安市市属医院洁净手术室尘埃粒子数和浮游菌均存在不同程度超标，尤其是二级医院应加强手术室环境质量管理。

Monitoring on dust particle and airborne microbe counts in the operating rooms in some municipal hospitals of Xi’an

ObjectiveTo understand environmental quality status of clean operating rooms in municipal hospitals of Xi’an, and provide reference for ensuring the clean quality of operating rooms.MethodsOn site specimen collection and detection were conducted to detect and analyze the cleanlinss of air in clean operating rooms in 15 hospital of Xi’an.ResultsA total of 51 operating rooms were monitored, secondary and tertiary hospitals had 24 and 27 operating rooms respectively; 26 were grade I and 25 were grade Ⅲ operating rooms. The qualified rates of dust particle≥0.5μm / particle size in grade I and grade Ⅲ clean operating rooms were 76.92% and 80.00% respectively, ≥5μm / particle size were 73.08% and 88.00% respectively. The qualified rates of dust particle counts in grade I and grade Ⅲ clean operating rooms were 61.54% and 80.00% respectively，difference was not significant（χ2=2.092，P＞0.05）. The qualified rate of dust particle counts in clean operating rooms in tertiary hospitals was significantly higher than secondary hospitals(85.19% vs 58.33%, χ2=4.600，P<0.05）. The qualified rates of airborne microbes in operating zone of secondary and tertiary hospitals were 87.50% and 92.59% respectively(P>0.05), in surrounding zone were 95.83% and 92.59% respectively (both P>0.05).ConclusionDust particle and airborne microbes in some clean operating rooms in municipal hospitals of Xi’an are beyond the standard, supervision and management should be strengthened.
