一种双链季铵盐消毒湿巾对手术室物体表面消毒效果评价

目的评价双链季铵盐消毒湿巾应用于手术室物体表面的消毒效果。方法通过问卷调查和现场采样定量细菌检验方法,对该季铵盐消毒湿巾实用性及其对物体表面的消毒效果进行检测评价。结果手术室内清洁前98%物体表面细菌总数超标。使用季铵盐湿巾和含氯消毒剂湿巾擦拭物体表面,作用30 min均可使细菌数降低至规范要求,而仅用清水湿巾擦拭无效。问卷调查结果显示,使用者对季铵盐消毒湿巾可接受性更好。结论双链季铵盐消毒湿巾对手术室物体表面消毒效果良好,且使用者可接受性较好。

Evaluation of disinfection effect of double-stranded quaternary ammonium salt disinfectant wipes on the surface of operating room objects

Objective To evaluate the disinfection effect of double-stranded quaternary ammonium salt disinfectant wipes on the surface of operating room objects.Method Through the questionnaire surveys and on-site sampling quantitative bacterial tests,the practicality of the quaternary ammonium salt disinfectant wipes and its disinfection effect on the surface of the objects were tested and evaluated.Result The total number of bacteria on 98% of the surface of objects before the cleaning in the operating room exceeded the standard.After wiping with quaternary ammonium salt wipes and chlorine-containing disinfectant wipes for 30 minutes,the number of bacteria on the surface of the objects could be reduced to the standard requirements,while it was invalid only by wiping with water wipes.Questionnaire surveys showed that users were more acceptable for quaternary ammonium disinfectant wipes.Conclusions The double-stranded quaternary ammonium salt disinfectant wipes have better disinfection effect on the surface of the operating room objects and are acceptable for users.
