【摘要】：目的通过与传统消毒方法的对比,观察一次性季铵盐类消毒湿巾的消毒效果。方法使用一次性季铵盐消毒湿巾和500 mg/L的含氯消毒剂对ICU物表进行擦拭,分别对消毒前、消毒后0 min、30 min、1 h、2 h、3 h、4 h的物表进行菌落总数采样及培养。结果消毒30 min,对照组与实验组达到最高的合格率,分别为96.7%、98.3%;对照组消毒4 h合格率为36.7%,而实验组的合格率可达到71.7%;两种消毒方法,各时间段抑菌率比较,仅消毒4 h有统计学差异,消毒湿巾、传统消毒抑菌率分别为(0.906±0.144)%、0.788±0.027,其余时间段抑菌率均无统计学差异。结论一次性消毒湿巾消毒物体表面效果可靠、方便、快捷,可取代传统消毒方法,成为医院物体表面理想的消毒方法,尤其是频繁操作的ICU更是最佳的物体表面消毒方法。
[Abstract]:Objective to compare with traditional disinfection methods. To observe the disinfection effect of disposable quaternary ammonium salt disinfectant wet napkins. Methods the disinfectant containing chlorine for 500 mg/L and disposable quaternary ammonium salt disinfectant were used to wipe the surface of ICU before disinfection. The total number of bacteria was sampled and cultured on the surface for 30 minutes, 1 hour, 2 h, 3 h and 4 h after disinfection. Results the results showed that the total number of colonies was collected and cultured for 30 min. The highest qualified rate was obtained in the control group and the experimental group, which were 96.7and 98.3, respectively. The qualified rate of disinfection in the control group was 36.7 hours, while that in the experimental group was 71.7%. The bacteriostasis rate of the two disinfection methods in each time period was significantly different only for 4 hours. The bacteriostasis rate of traditional disinfection was 0.906 卤0.144%, and that of the traditional disinfection method was 0.906 卤0.144%. There was no statistical difference in bacteriostasis rate in the rest period. Conclusion the surface effect of disposable disinfectant wet towel is reliable, convenient and quick, and can replace the traditional disinfection method. It has become the ideal disinfection method for hospital object surface, especially the frequently operated ICU is the best disinfection method.
