Indications of dialysis after failure of medical management include

Dialysis is indicated when medical management fails to control volume overload, hyperkalemia, or acidosis; in some toxic ingestions; and when there are severe complications of uremia (asterixis, pericardial rub or effusion, encephalopathy, uremic bleeding). One of the major complications of hemodialysis is hypotension, paicularly in the critically ill. Ref: Harrison 19e 1811
