摘要
目的了解医院血液透析用水卫生质量和处理系统维护消毒情况,以加强对血液透析用水的管理。方法通过现场采样检测和问卷调查方式,对某市医院血液透析用水质量及其管理现状进行调查。结果共调查该市辖区内32家医院血液透析室,部分医院血液透析室水处理系统中反渗透膜更换周期最长为4年,透析用水处理设备消毒频次为半个月至6个月不等。医院透析用水处理系统消毒方法主要采用柠檬酸加热消毒法,少数采用次氯酸钠或混合消毒剂冲洗消毒法,不同消毒方法处理后水中检出细菌总数差异无显著统计学意义。结论所调查的医疗机构透析用水卫生质量合格率较高,水处理系统管理制度和水处理系统消毒管理措施有待加强。
Objective To investigate the hygienic quality and the maintenance and disinfection of water treatment system,so as to strengthen the management of dialysis water. Methods On- site sampling examination and questionnaire survey were used to investigate the quality and management status of dialysis water. Results 32 hospital dialysis room were investigated. The longest replacement cycle of reverse osmose membrane was 4 years in some hospitals. The water treatment system was disinfected for 0. 5 ~ 6 months once a time. The disinfection method for water treatment system was citric acid heating in most of hospitals in the city. Sodium hypochlorite and mixed disinfectant washing were used in a small number of hospitals. The total bacteria count of dialysis water were not significant difference in different disinfection methods. Conclusion The qualified rate of dialysis water is high in investigated hospitals. But the management of water treatment system and disinfection measure of dialysis water should be strengthened.
