目的 掌握不同消毒剂及同一消毒剂不同浓度下对偶发分枝杆菌的杀灭作用。指导临床选择适当消毒剂和消毒方式 ,控制与预防发生偶发分枝杆菌院内感染。方法 选择常用消毒剂在不同浓度下对偶发分枝杆菌进行定量杀灭试验。结果 碘酒、碘伏、乙醇在常用浓度下对偶发分枝杆菌有较好的杀灭效果。戊二醛、过氧乙酸、含氯消毒剂在较高浓度时有较好的杀灭效果。结论 依据试验结果指导临床选择敏感消毒剂对收治偶发分枝杆菌院内感染病人的特殊病区进行消毒、预防 ,在 1年的治疗、护理期间 ,未继发偶发分枝杆菌院内感染新病例。
Objective To master the killing effect of different disinfectants and the same disinfectant on Mycobacterium fortuitum at different concentrations. Guide the clinical choice of appropriate disinfectants and disinfection methods to control and prevent the occurrence of occasional Mycobacterium nosocomial infection. Methods The commonly used disinfectants were selected to test the mycobacterium fortuitum in different concentrations. Results Iodine wine, iodophor, ethanol at the usual concentrations of Mycobacterium fortuitum better killing effect. Glutaraldehyde, peracetic acid, chlorine disinfectant at higher concentrations have better killing effect. Conclusion According to the results of the experiment, we guide the clinical selection of sensitive disinfectant to disinfect and prevent special ward of patients with nosocomial infection of Mycobacterium fortis. During the one year of treatment and nursing, new cases of nosocomial mycobacterium vaccae have not been secondary.
