PDA污染情况调查及消毒方法研究

Investigation on pollution and study on disinfection method of PDA

目的:观察护理人员使用的PDA细菌污染的情况,探讨3种消毒方法的效果。方法:随机抽取本院护理人员使用的PDA 30部进行细菌培养,随机平分为3组,分别用75%酒精、手消毒剂、紫外线照射消毒,对结果进行统计分析。结果:由护理人员使用的PDA在消毒前细菌超标率100%,消毒后细菌超标率下降到3%,消毒前后比较,差异有统计学意义(P<0.05)。结论:加强手卫生,做好PDA清洁消毒和维护,防止院内感染。采用手消毒剂消毒PDA为最理想的消毒方法。

Objective:To observe the situation of bacterial contamination of PDA used by nurses,and to explore the effect of 3 disinfection methods.Methods:30 PDA used by nursing staff in our hospital were randomly selected for bacterial culture.They were randomly divided into the 3 groups,respectively,with 75% alcohol,hand disinfectant,UV irradiation for disinfection,and we made a statistical analysis of the results.Results:The bacterium ex-standard rate of PDA used by nurses was 100% before disinfection,and the rate of bacteria was decreased to 3% after disinfection;the difference was statistically significant before and after disinfection(P < 0.05).Conclusion:Strengthen hand hygiene,do a good job in PDA cleaning and disinfection and maintenance can prevent nosocomial infection.Using hand disinfectant to disinfect PDA is the most ideal method.
