Open Access Abstract Introduction To evaluate the cause of methemoglobinemia in patients undergoing extended daily hemodialysis hemodiafiltration we analyzed the relationship between methemoglobinemia and the water disinfection schedule of the hospital. Methods We reviewed all arterial blood gas analyses obtained over a one-year period in patients undergoing extended hemodialysis hemodiafiltration and compared the methemoglobin concentrations obtained on the days when the water supply was disinfected using a hydrogen peroxide silver ion preparation with data measured on disinfection-free days. Results The evaluation of 706 measurements revealed a maximum methemoglobin fraction of 1.0 0.8 1.2 median and 25th 75th percentiles during hemodialysis hemodiafiltration on the .
