洁净手术室数字化设备表面污染情况调查

Survey of surface contamination of digital equipment in clean operating room Survey of surface contamination of digital equipment in clean operating room

目的：了解洁净手术室数字化设备的细菌污染状况，拟定合理的防控措施。方法2014年3月选取我院10间手术间共20个单位的数字化设备（包括电脑主机、键盘、鼠标、显示器、条码扫描及打印机）表面进行细菌分布情况及种类监测，4月采取新的防控措施后再次对该设备进行监测分析。结果3月份共检出44份阳性标本，4月共检出8份阳性标本，差异有统计学意义（ P＜0．05）；3月检测出病原微生物菌19株，4月未检测到各类病原微生物，实施新防控措施前后差异显著。结论洁净手术室内不同区域数字化设备存在不同差异的细菌污染，采取有效的防控措施能够明显改善污染状况。

Objective To explore the condition of bacterial contamination of digitizing equipment in clean operating room, and de-velop reasonable control measures.Methods In march of 2014 , a total of 20 units of the surface of the digital equipment （ including com-puter host, keyboard, mouse, display, barcode scanning and printer） were selected from 10 operating rooms, bacterial distribution and types were monitored, again after April new prevention and control measures were taken to conduct monitoring and analysis of the device.Results 44positivespecimenswerecheckedoutinMarch,eightmasculinespecimenwerecheckedinApril,thedifferencewasstatisticallysignifi-cant （P〈0.05）, 19 strains of pathogenic microorganisms bacteria were checked out in March, none of pathogenic microorganisms was detec-ted in April, the significant difference before and after the implementation of the new prevention and control measures.Conclusions There exist different bacterial contamination in the different regions digital devices in the clean operating room, effective prevention and control measures can greatly improve the pollution condition.
