【摘要】：目的比较不同采样方法对层流洁净手术室空气细菌总数动态变化趋势的监测结果,为层流洁净手术室空气动态采样方法的选择提供参考数据。方法采用自然沉降法和空气微生物采样器采样法,对某医院层流洁净手术室空气中细菌总数变化趋势进行监测与比较。结果自然沉降法与仪器采样法监测层流洁净手术室手术过程中空气细菌总数呈波浪状变化,两种方法采样所得数据之间的秩相关系数为0.733。提示两种采样方法检出的细菌总数差异有统计学意义,仪器采样法采样得到的细菌总数明显高于自然沉降法。结论两种空气采样方法对手术室空气细菌总数监测结果存在差异,但均能体现其动态变化趋势,仪器采样法更适合手术过程中空气细菌总数的动态监测。
[Abstract]:Objective to compare the results of different sampling methods in monitoring the trends of total bacterial counts in laminar clean operating room air, and to provide reference data for the selection of laminar clean operating room air dynamic sampling method. Methods the natural sedimentation method and the sampling method of air microorganism sampler were used to monitor and compare the change trend of the total number of bacteria in the air of a hospital laminar flow clean operating room. Results the total number of bacteria in air was wavy during laminar clean operating room operation by natural sedimentation method and instrument sampling method. The rank correlation coefficient between the two methods was 0.733. It is suggested that the total number of bacteria detected by the two methods is statistically significant, and the total number of bacteria collected by the instrument sampling method is obviously higher than that by the natural sedimentation method. Conclusion there is a difference between the two air sampling methods in monitoring the total number of bacteria in the operating room, but both of them can reflect the dynamic change trend. The instrument sampling method is more suitable for the dynamic monitoring of the total bacterial count in the air during the operation.
