2014—2018年徐州市血液透析用水和透析液污染状况调查

目的 了解徐州市血液透析用水和透析液污染状况,分析污染原因并提出针对性的预防对策。方法 对2014—2018年徐州市开展血液透析的24家医院进行透析用水和透析液微生物监测,对结果进行统计分析。结果 采集反渗水258份、透析液900份,微生物监测总合格率分别为89.92%、82.89%。反渗水和透析液微生物监测合格率逐年升高。近端反渗水的合格率高于远端(χ2=4.28,P<0.05),透析机入口的透析液合格率高于出口(χ2=4.63,P<0.05),二级医院的反渗水和透析液合格率均高于三级医院。结论 徐州地区血液透析用水合格率偏低,医院及监管部门应采取相应措施,进一步确保血液透析安全。

Investigation on hemodialysis water and hemodialysis fluid pollution in Xuzhou City from 2014 to 2018

Objective To understand the hemodialysis water and hemodialysis fluid pollution in Xuzhou City, analyze the causes of pollution, and propose a targeted prevention strategy. Methods A microbial monitoring of the hemodialysis water and hemodialysis fluid was carried out in 24 hospitals of Xuzhou Cityfrom 2014 to 2018, and the results were statistically analyzed. Results A total of 258 samples of reverse osmotic water and 900 samples of dialysis fluid were collected and their qualified rates of microbial detection were 89.92% and 82.89% respectively.The qualified rates of microorganism detection in reverse osmotic water and dialysis solution have been growing each year.The qualified rate of proximal reverse osmotic water was higher than that of the distal end (χ2=4.28, P<0.05). The qualified rate of the microbiological detection of dialysate from the entry of the dialysis machine was higher than that of dialysate from the export (χ2=4.63, P<0.05), and the qualified rates of the reverse osmotic water and dialysis fluid in the secondary hospitals were both higher than those in the tertiary hospitals. Conclusion The qualified rate of the hemodialysis water in this area is low, and the hospitals and supervision department should take corresponding measures to further ensure the safety of hemodialysis.
