【摘要】：目的研究不同消毒方法对物体表面污染的耐药菌消毒效果。方法通过模拟现场消毒实验方法,观察不同化学消毒剂和消毒方法对在物体表面污染的耐药菌消毒效果。结果以含2 000 mg/L浓度的过氧乙酸、有效氯1 000 mg/L的含氯泡腾片水溶液和季铵盐消毒湿巾擦拭消毒硬质表面,并作用15 min,对表面上污染的多重耐药鲍曼不动杆菌和MRSA平均杀灭均可达到90%以上;酸性氧化电位水原液擦拭消毒物体表面作用2 h,对上述2种多重耐药菌平均杀灭率在85%左右。结论本研究中4种消毒方法对物体表面污染的两种多重耐药菌消毒效果以季铵盐消毒湿巾性价比较高,可考虑优先选择用作物体表面一般清洁消毒。
[Abstract]:Objective to study the disinfection effect of different disinfection methods on drug-resistant bacteria contaminated by object surface. To observe the disinfection effect of different chemical disinfectants and disinfection methods on drug-resistant bacteria contaminated on the surface of objects. Results Peracetic acid containing 2 000 mg/L concentration was used. The effervescent tablets containing chlorine with available chlorine of 1 000 mg/L and quaternary ammonium salt disinfectant wipes were used to disinfect hard surfaces for 15 min. The average killing rate of Acinetobacter baumannii and MRSA on the surface was more than 90%. The surface of the disinfectant was wiped by acidic oxidizing potential water solution for 2 h. The average killing rate of the two multidrug resistant bacteria was about 85%. Conclusion the disinfection effect of the four disinfection methods on the surface contamination of two multidrug resistant bacteria is higher than that of quaternary ammonium salt. Preference may be given to general cleaning and disinfection of object surfaces.

【正文快照】： 近年来,多药耐药菌(MDROs)已经逐渐成为医院感染的重要病原菌,2010年版《多重耐药菌医院感染预防与控制技术指南(试行)》中指出,环境物体表面的清洁消毒对防控耐药菌的重要性〔1〕。目前国内医疗机构环境物体表面消毒方式较为多样,对于耐药菌污染的物体表面消毒也未见明确的推
