目的 :对手术室空气消毒效果进行评价。方法 :对 3个不同时期的手术室进行空气动态监测及不同消毒方式的效果进行比较。结果 :合理布局的新手术室消毒效果优于旧手术室 ,在南方气候条件下 ,臭氧消毒机消毒效果优于紫外线的消毒灭菌效果。结论 :手术室的合理布局、加强监测、应用新型有效的空气消毒器对手术室空气消毒效果有重要作用 Objective: To evaluate the effect of air disinfection in operating room. Methods: Three different periods of the operating room for air dynamic monitoring and the effect of different disinfection methods were compared. Results: The new operating room with reasonable layout had better disinfection effect than the old operating room. In the southern climate, the disinfection effect of ozone disinfection machine was better than that of UV disinfection and sterilization. Conclusion: The rational layout of the operating room to strengthen monitoring, application of new and effective air disinfection of the operating room air disinfection has an important role
