the quality of dialysis water: a case study in the educational hospitals of yazd, iran

background the chemical and physical quality of water used for dialysis fluid is a vital factor in the patients overall care who receive dialysis. therefore, the water used for this purpose must be treated with advanced methods before being used for dialysis. conclusions the evaluation of hemodialysis water quality showed that these hospitals were not significantly polluted and the water quality complied with aami and eph standard limits. results based on results of the research, except chloride that its mean concentration was higher than the eph standard, mean concentrations of cations and other compounds were significantly less than the standards (p < 0.01). also there was a significant difference between the measured parameters in the dialysis machines input water in two educational hospitals with 99% confidence. materials and methods this cross-sectional study is performed in three months (october to december) in 2013. this research was conducted on 24 samples of dialysis machines input water. the samples were tested by titrimetric method, turbid metric method, flame photometer, ph meter, and ec meter. the spss v16.0 software was used for statistical analyses. objectives the current study aimed to determine the chemical and physical quality of dialysis machines input water and compare it to the standards of association for the advancement of medical instrumentation (aami) and european pharmacopeia (eph) in yazd educational hospitals, i.e. shahid sadoughi and shahid dr. rahnamoon.
