Assessing biological and chemical indicators of water used in Dialysis Ward of one of the Sanandaj hospitals

The used dialysis liquid is considered as the largest volume of water used in medicine. The concentrated liquid is manufactured in equal commercial quality and fully controlled procedure. But the quality of water used may pose different qualities. Using ordinary tap water to dialysate has always the possibility of transmission of potentially toxic substances from the patient's blood along with it. Therefore, the quality of water used to prepare dialysis solution is of great importance. The aim of this study was to determine microbial and chemical parameters of water used in dialysis center in one of the hospitals in Sanandaj City. This was a cross-sectional descriptive study in which 35 water samples from 10 hemodialysis machine were randomly selected. The study was performed in the second quarter of 2015. The chemical sampling was carried out once per month while the microbial sampling was taken twice per month. Evaluation of chemical and microbial indicators of water used in the dialysis ward of the hospital in Sanandaj showed that the water does not have microbial contamination but exceeding elements such as nitrite, sodium, calcium, and magnesium than the standard in some of the samples make it essential to do further monitoring of the water treated in dialysis ward.
