Hemodialysis patients rely mainly on potassium removal during each dialysis session as potassium homeostasis is mainly regulated by the kidneys. A recent study suggests that predialysis hyper- and hypokalemia might increase the risk of death. The study findings were published in the journal Kidney Medicine on October 22, 2021.
Predialysis serum potassium is a known modifiable risk factor for death in hemodialysis patients, especially for hypokalemia, this risk may be underestimated. Therefore, Dr Esther N.M. de Rooij MD and her team investigated the relation between predialysis serum potassium and death in incident hemodialysis patients and whether there is an optimum level.
