摘要
目的了解手术室空调滤尘网带菌状况,以便采取相应措施控制院内感染。方法检测手术室紫外线消毒前后的空气菌落数和空调滤尘网表面菌落数;滤尘网用500 mg/L含氯消毒剂浸泡消毒,并于消毒后即时、1周、2周、3周、1月采样进行细菌培养。结果紫外线消毒前后,手术室空气菌落数的差异有统计学意义,空调滤尘网表面菌落数的差异无统计学意义。滤尘网消毒后即时其表面细菌数符合Ⅱ类环境的要求,消毒后2周内细菌数与消毒后即时的差异无统计学意义,而消毒3周后细菌数与消毒后即时的差异有统计学意义。结论应定期对空调滤尘网进行清洗与消毒,消毒液可选用500 mg/L含氯消毒剂,清洗消毒间隔时间以2周为宜。
Objective To understand the bacteria - existing status of the air - condition＇ s filter in operation room so aa to carry out the corresponding oountermeasures. Method The floras in air and in the surface of air condition＇ s filter were collected both before and after ultraviolet disinfection in the operation room. The filter was disinfected with 500mg/L chlorine disinfectant, then the bacteria were respectively collected and cultivated in different time that ware just after disinfection, 1 week, 2 weeks, 3 weeks and 1 rnonth after disinfection. Result The flora number in air before and after ultraviolet disinfection had statistical significance, while the flora number in the surface of air- condition＇ s filter had no statistical significance. Besides, the flora number in the surface of filter just after disinfection meet the demands of environment type Ⅱ , and the flora number 2 weeks after disinfection had no statistical significance with flora number of just after disinfection, while 3 weeks after disinfection had obvious statistical significance with flora number of just after disinfection. Conclusion The air- condition＇s filter should be cleared and disinfected termly, usually once for 2 weeks. 500mg/L chlorine disinfectant is recommended for the filter＇s disinfection.
