摘要 目的了解层流洁净手术室不同时段空气质量。方法对北京部分医院百级、万级洁净手术间进行静态(自然沉降法)和动态空气采样(从手术开始到结束不同阶段的细菌菌落数)及过滤器检漏测试。结果 2008、2009年静态空气采样超标率≤9.40%;2008年41.67%的洁净手术室动态实测空气细菌总数高于《医院洁净手术室污染控制规范》标准值;50.00%的过滤器存在泄漏;经检修后,2009年过滤器检漏合格率为100.00%,动态空气细菌超标率仅为5.00%;对手术不同阶段空气细菌动态监测,从手术开始细菌浓度逐渐增加,至缝合后细菌浓度缓慢降低。结论动态空气细菌监测指标较静态空气细菌指标更为敏感有效,更能反映洁净手术部实际空气质量。 OBJECTIVE To investigate the air quality of different stages in clean operating rooms.METHODS Static air sampling method(natural sedimentation method)and dynamic air sampling method(the number of bacterial colonies were monitoring at different stages)were used to sample the air in clean operating rooms(Grades 102 and 104)in some hospitals in Beijing,and the leak tests was performed by the filter.RESULTS According to the surveys of 2008 and 2009,the exceed allowable limit rate of static sampling air was less than 9.40%.The results of dynamic sampling showed that the total bacterial number in air of dynamic state exceeded the standard value of Standard for the contaminant control in clean operating department of hospitals,with 41.67% of the clean operating rooms in 2008;leak tests indicated that the leakage existed in 50.00% of the filter.After repair,100.00% of the filter passed the 2009 leak tests,and the dynamic microbiological monitoring results released that the unqualified rate was only 5.00%.The dynamic monitoring results of the concentration of bacteria in air in different stages showed that the static sate(non-operating state)was lower and the concentration increased gradually from the beginning of surgery and then began to decrease slowly after the suturing.CONCLUSION Compared to static monitoring indicators,dynamic monitoring indicators which are much more sensitive and effective can better indicate the actual air quality in clean operating department.
