湖南省2009-2011年医院血液透析用水卫生质量分析

目的了解近3年湖南省医院血液透析用水的卫生状况,为血透用水卫生质量的规范化管理提供科学依据。方法于2009-2011年先后采集湖南省的77家不同等级医院的血液透析用水样品,按照《血液透析用水卫生标准》进行理化指标、微生物指标的检测分析和判定。结果血透用水中氯化物、钙、氯胺、内毒素和菌落总数等超标率分别为11.7%、2.6%、2.6%、23.4%、1.3%,其他项目均合格。三甲医院和非三甲医院透析用水合格率差异无统计学意义。结论影响湖南省血液透析用水卫生质量的主要因素是氯化物和内毒素,定期监测、及时更换水处理设备组件、加强输配水管路的清洗消毒等措施是提高血液透析用水水质的关键。

Analysis on Sanitary Quality of Hemodialysis Water in Hospitals of Hunan Province During the Period of 2009 - 2011

Objective To investigate the sanitary quality of hemodialysis water among hospitals of Hunan Province in the past 3 years,and to provide a scientific basis for the standardized management of hemodialysis water.Methods The samples of hemodialysis water were collected from 77 different levels of hospitals in Hunan Province from 2009 to 2011.Physicochemical and microbial indexes of the samples were measured and judged according to Sanitary Standard for Hemodialysis Water.Results The disqualification rates of chloride,calcium,chloramine,esotoxin and total number of bacterial colony were 11.7%,2.6%,2.6%,23.4%,and 1.3%,respectively.The other inspection items were qualified.But the qualified rates showed no statistically significant difference between 3A grade hospitals and other grades hospitals.Conclusions The main influencing factors for sanitary quality of hemodialysis water in Hunan are chloride and esotoxin.The key measures to improve the quality of hemodialysis water are to monitor regularly,replace water treatment device in time,wash and disinfect the water pipes.
