医院常用消毒剂对耐药金黄色葡萄球菌的杀灭效果观察

Observation on the killing effect of common disinfectants in hospital on drug-resistant Staphylococcus aureus

目的观察医院常用消毒剂对耐药金黄色葡萄球菌的杀灭效果,为选购医院消毒剂提供参考。方法采用悬液定量杀菌试验,对4种医院常用消毒剂杀灭临床分离的耐药金黄色葡萄球菌效果进行观察。结果用60%乙醇、有效氯400 mg/L的含氯泡腾片消毒液、有效碘200 mg/L的碘伏消毒液均可在1 min之内完全杀灭耐药金黄色葡萄球菌。75%乙醇消毒液和某含聚六亚甲基胍复合醇手消毒液均可在30 s达到完全杀灭耐药金黄色葡萄球菌。结论4种医院常用消毒剂在日常使用浓度下均能有效杀灭临床分离的耐药金黄色葡萄球菌。

Objective To observe the killing effect of common disinfectants in hospital on drug-resistant Staphylococcus aureus,so as to provide reference for the purchase of hospital disinfectants.Methods The suspension quantitative bactericidal test was used to observe the killing effect of 4 kinds of common disinfectants in hospital on clinically isolated drug-resistant Staphylococcus aureus.Results 60%ethanol,400 mg/L chlorine-containing effervescent tablet disinfectant,and 200 mg/L iodophor disinfectant solution could completely kill drug-resistant Staphylococcus aureus in 1 min.75%ethanol disinfectant and a hand disinfectant containing polyhexamethylene hydrazine complex alcohol could completely kill drug-resistant Staphylococcus aureus in 30 s.Conclusion The four disinfectants commonly used in the hospital of this study can effectively kill the clinically isolated drug-resistant Staphylococcus aureus at daily use concentrations.
