目的了解病历夹细菌污染情况,确定有效的消毒方法和消毒时间。方法对成都市中西医结合医院病区20只不锈钢病历夹表层进行了消毒前,消毒后当日、3d、7d、14d、30d的细菌学检测。结果消毒前病历夹的细菌污染量超过卫生部《消毒技术规范》中规定各类普通病房物体表面细菌菌落总数≤10cfu/cm2的卫生标准,并检出金黄色葡萄球菌和大肠杆菌等致病性微生物。用500mg/L含氯消毒液进行擦拭消毒后当日、3d、7d、14d病历夹的细菌污染量均未超过以上卫生标准,消毒后30d的细菌污染量超过了以上卫生标准。结论用500mg/L含氯消毒液每2周擦拭消毒病历夹1次,是一种简单、快速、有效的方法。
OBJECTIVE To understand the bacterial contamination of medical records and to determine the effective disinfection methods and disinfection time. Methods The surface of 20 stainless steel medical records in the ward of Integrative Medicine Hospital of Chengdu were sterilized before sterilization, on the 3d, 7d, 14d and 30d after disinfection.
