三种消毒方法对妇科病房诊床消毒效果的观察

Observation on the disinfection effect of three disinfection methods on the examination bed of gynecological wards

目的观察3种消毒方法对妇科病房诊床的消毒效果。方法以妇科病房检查床为研究对象,采用500 mg/L含氯消毒液、75%乙醇和季铵盐一次性消毒湿巾对检查床进行消毒,并检测检查床表面消毒前、消毒后30 min、1 h、2 h、4 h、14 h的细菌菌落数,比较3种消毒方法消毒效果及抑菌持续时间。结果3种消毒方法在擦拭消毒后4 h内,所有妇科诊床均保持在卫生标准允许的合格状态。在消毒后14 h,诊床表面菌数恢复到消毒前污染状态。结论3种消毒方法均可用于妇科诊床消毒,但季铵盐消毒湿巾综合性价比更好。

Objective To investigate the disinfection effect of three disinfection methods on the examination bed of gynecological wards.Methods The examination beds of gynecological wards were used as the research object.The examination bed was disinfected with 500 mg/L chlorine-containing disinfectant,75%ethanol and quaternary ammonium salt disposable disinfection wipes,and the surface of the examination bed was detected for bacterial colonies before disinfection,30 min,1 h,2 h,4 h,14 h after disinfection.The disinfection effect and duration of bacteriostasis of the three disinfection methods were compared.Results Within 4 h after wiping and disinfection,all gynecological examination beds were kept in a qualified state as allowed by the hygiene standards.Since 14 h after disinfection,the bacterial counts on the surface of the examination bed returned to the contamination state before disinfection.Conclusion The three disinfection methods can be used for disinfection of gynecological examination bed,but the comprehensive cost performance of quaternary ammonium salt disinfection wipes is better.
