Potassium
In chronic renal failure (CRF), hyperkalaemia
does not tend to become a problem until there is severe impairment of function (GFR <
20 ml/min/1.73m2). It is managed by:
-
reducing the intake of foods rich in potassium
-
treating acidosis
-
stopping drugs which exacerbate hyperkalaemia
(K-sparing diuretics, ACE inhibitors)
-
ion exchange resins can be taken orally
Failure to control hyperkalaemia is an indication for dialysis.
