摘　　要：目的:比较独立单元空气净化器和紫外线消毒对介入手术室空气消毒效果,探讨空气净化器和紫外线消毒的临床应用价值。方法:分别利用空气净化器和紫外线灯对介入手术室进行相同时间处理,用平板自然沉淀法分别对比两种处理方式对介入手术室自然菌的消毒效果,同时回顾性分析广州医科大学附属第三医院2015年1月~2016年12月两种消毒方式处理后5 830名手术病人术后感染情况。结果:在经过24个月相同时间处理后,紫外线灯对介入手术室自然菌的杀菌率达85.04%(283.1/332.9),而空气净化器对介入手术室自然菌的杀菌率达83.72%(283.05/338.1),两种方法消毒后空气菌落数分别为(43.69±23.08)cfu/m3和(45.87±18.13)cfu/m3,介入手术术后感染率分别为0.49%(15/3 050)和0.29%(8/2 780);两种方法的杀菌效果、空气菌落数及介入手术术后感染率均无显著性差异(P>0.05)。结论:空气净化消毒效果与紫外线无异,然而由于其可持续使用,贯穿手术过程且对人体无害,空气净化消毒器应作为介入手术室消毒的首要选择。Objective To assess the air disinfection effects of air purification equipment vs ultraviolet radiation for interventional room and discuss their clinical application values.Methods Air purification equipment and ultraviolet radiation were applied individually for the same time to achieve the air disinfection of interventional room.Air bacteria were collected with plates before and after air disinfection,thereby evaluating the air disinfection effects.After the air disinfection with two kinds of methods,the postoperative infection rates of 5 830 patients who were treated in the Third Affiliated Hospital of Guangzhou Medical University from January 2015 to December 2016 were respectively analyzed.Results After the disinfection treatment for 24 months,ultraviolet radiation and air purification equipment had a sterilizing rate of 85.04%(283.1/332.9)and 83.72%(283.05/338.1)against air bacteria in interventional room.The number of air bacteria rates after the disinfection with air purification equipment and ultraviolet radiation were(43.69±23.08)cfu/m3 and(45.87±18.13)cfu/m3,respectively,and the postoperative infection rates were 0.49%(15/3 050)and 0.29%(8/2 780).No significant difference was found between air purification equipment and ultraviolet radiation regarding sterilizing effect,number of air bacteria and postoperative infection rate(P>0.05).Conclusion Air purification equipment which has a disinfection effect similar to that of ultraviolet radiation should be the first choice for the disinfection of interventional room,because it can be used continuously and throughout the operation and is harmless to human.
