三种不同空气消毒方法在手术室的应用效果比较(1)
[摘要] 目的:观察三种不同的空气消毒方法在手术室空气消毒中的应用效果,寻求手术室的最佳空气消毒方法。方法:对我院一间普通手术室采用三种不同的空气消毒方法进行消毒,并对三种方法的消毒效果、不同物体表面细菌监测结果及各细菌检出率与构成比进行比较。结果:手术室空气消毒30 min后,动态消毒机法空气培养监测无菌率为61.11%,显著高于紫外线灯照射法的无菌率(32.43%)和醋酸氯己定喷雾法无菌率(36.84%),P0.05);各种细菌检出率和构成比也均低于紫外线灯照射法和醋酸氯己定喷雾法。结论:动态消毒机法克服了传统静态消毒方式的缺点,杀菌作用强,效果好,优于其他传统消毒方法,适合基层医院手术室推广。

[Abstract] Objective: Observation three different air disinfection methods in the operating room air disinfection effect of the application,seeking the best operating room air disinfection method.Methods:Using three different air disinfection method to disinfect our hospital operating room, comparison of the three disinfection effect, different objects surface bacteria monitoring results,and observed bacterial detection rate and the ratio. Results: After operating room air disinfection 30 minutes, dynamic machine disinfection of air-monitoring training aseptic rate 61.11%,significantly higher than UV light exposure method's 32.43% and chlorhexidine acetate spray method's 36.84%(P 75 μW/cm2,照射时间为1 h。
1.2.2醋酸氯己定喷雾法采用有效含量为3 800~4 000 mg/L的醋酸氯己定空气消毒剂(新尔奇牌),按5 ml/m3剂量喷雾消毒,作用时间30 min。
1.2.3动态消毒机法选用格王牌动态消毒机两台,安装在手术间双侧壁距地面高度2 m 以上的位置,定时每天定时消毒6 h。
1.3统计学方法
使用SPSS 13.0 统计软件进行统计分析,定量资料组间比较采用t检验,定性资料组间比较采用χ2检验,α=0.05。
2 结果
2.1三种消毒方法消毒30 min后空气培养结果比较
三种消毒方法用于手术室空气消毒30 min后的空气培养监测结果显示,动态消毒机法共检测出22次无菌,无菌率为61.11%,紫外线灯照射法共检测出12次无菌,无菌率为32.43%,醋酸氯己定喷雾法共检测出14次无菌,无菌率为36.84%。动态消毒机法无菌率显著高于其他两组(P, http://www.100md.com(徐冬梅)
