常用消毒剂对偶发分枝杆菌的杀灭效果

Study on the Sterilizing Function of Different Disinfectants under Different Concerntration of Mycobacilli

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 Mastering the sterilizing function of different disinfectants and one disinfectant under different concentrations for casual-occurred mycobacilli,instructing the clinical proper option of disinfectants and sterilizing methods,controlling and preventing in-hospital infection occurrence of casual-occurred mycobacilli. Methods Selecting frequent-use disinfectants to conduct the quantitative sterilizing experiment for casual-occurred mycobacilli under different concentrations. Results Tincture of iodine?PVTI?alcohol have better sterilizing effect for casual-occurred bacilli under frequent-use concentrate ions.Phenyl dialedhyde,peracetion acid,chlorine-contained disinfectant have better sterilizing effect under highe concentrations. Conclusions According to the experiment result,directing the clinical option of sensitive disinfectants to conduct the special infected area sterilization and prevention of casual-occurred mycobacilli.During one year treatment and nursery no new case of casual-occurred mycobacilli in-hospital infection has happened.
