【摘要】：目的比较紫外线空气消毒机循环风消毒和空气净化屏消毒两种方法对介入手术室连台手术空气的消毒效果,为制定控制医院感染措施提供依据。方法用平板自然沉降法于手术室空气消毒后不同时段采样检测,观察两种消毒方法对连台介入手术室空气的杀菌效果。结果两种消毒方法对连台手术术前空气都有较好的消毒效果(P0.05),利用紫外线消毒,手术室的各采样时段菌落检测结果有显著差异(P0.01),随着距离消毒时间的延长,菌落数增加。空气净化屏对手术室进行持续动态空气净化,使手术全过程空气中菌落数符合国家卫生消毒标准。结论空气净化屏24 h持续净化可以缩短手术间隔时间,急诊随到随做,防止医院交叉感染的发生。
[Abstract]:Objective to compare the disinfection effect of two kinds of disinfection methods of ultraviolet air disinfector, circulating air disinfection and air purifying screen, on the air of interventional operation room with operation table. To provide the basis for the control of nosocomial infection, the natural sedimentation method was used to sample and detect the air in the operating room at different time after disinfection. The sterilization effect of two disinfection methods on the air of interventional operating room was observed. Results the two disinfection methods had better disinfection effect on the air before operation with connected stage operation, and the ultraviolet radiation was used to sterilize the air. There were significant differences in the results of colony detection among different sampling periods in operating room. The number of colonies increased with the prolongation of the distance of disinfection time. The air purifying screen was used to purify the operating room continuously and dynamically. The number of bacteria in the air during the operation was in line with the national hygienic disinfection standard. Conclusion 24 h continuous purification of air purifying screen can shorten the operation interval and prevent the occurrence of hospital cross infection.
