Chemical Quality of Water Entrance to Dialysis Machines and Its Comparison with AAMI and EPH Standards in Hospitals of 22Bahman gonabad.

The presence of certain chemical compounds in dialysis water which enter patients’ bodies through hemodialysis can cause various problems such as acute poisoning, brain damage, osteoarthritis. Therefore, applying the standards for dialysis water is indispensible. This study was carried out to determine the chemical quality of water entrance to dialysis machines and its comparison with AAMI and EPH standards in the hospital22 Bahman’s Gonabad. This cross-sectional study was performed on 66 samples including water systems used in dialysis units in the 22 Bahman hospital Gonabad. Samples were analyzed by Atomic Absorption, DR4000 and Flame photometer. Data were analyzed by SPSS software and presented independent t-test (p<0.5). The results of this study showed the measured values were less than standard reference values. In all samples Measured, elements and compounds such a sodium, potassium, fluoride and nitrate less than standard, but only a temporary calcium concentrations expressing as difficulty were higher than standard level. This result showed that the averages of all measured compounds are less than standard, representing high quality water hospital for dialysis. This is while high calcium concentration in some samples needs to be further assessed.
