目的了解石家庄市托幼机构物体表面的消毒现状,比较不同消毒方法的消毒效果。方法随机抽取石家庄市53所托幼机构进行调查,采集222份物体表面进行监测。结果托幼机构物体细菌总数中位数为6.00 cfu/cm2,不同物体表面的细菌总数分布差异有统计学意义(χ2=15.100,P<0.01),不同物体表面的合格率差异有统计学意义(χ2=18.96,P<0.01),门把手合格率较低。84液和乙醇的消毒合格率差异有统计学意义(χ2=8.19,P<0.01)。结论不建议托幼机构使用乙醇进行物体表面消毒。托幼机构应提高门把手的清洗消毒频次。
Objective To understand the disinfection of the surface of kindergarten institutions in Shijiazhuang City, and to compare the disinfection effects of different disinfection methods. Methods Fifty-five institutions in Shijiazhuang were randomly selected for investigation. 222 objects were collected for monitoring. Results The median total number of bacteria in the nursery was 6.00 cfu / cm2. The total number of bacteria on the surface of different objects was significantly different (χ2 = 15.100, P <0.01), and there was significant difference in the passing rate of different objects χ2 = 18.96, P <0.01), the door handle lower pass rate. 84 liquid and ethanol disinfection qualified rate difference was statistically significant (χ2 = 8.19, P <0.01). Conclusion It is not recommended for nurseries to disinfect surfaces with ethanol. Kindergarten child care institutions should improve the frequency of cleaning and disinfection.
