Abstract
Acute renal failure (ARF) can be treated since the end of the 1970s, either by continuous forms of extracorporeal treatment (CRRT) or by intermittent dialysis (IHD). The main advantages of CRRT as opposed to IHD are greater hemodynamic stability, avoidance of rapid fluid and electrolyte shift with an easy fluid management and nutrition without restriction. The necessity for continuous anticoagulation is the most important disadvantage. Starting dose in CRRT should not exceed 35 ml/kg bw/h and can be reduced after 2-3 days not falling below 20 ml/kg bw/h. Weekly Kt/V in IHD should reach 4.5-5. In many cases, IHD should be performed daily. There are a few critically ill patients, especially those with sepsis and septic shock, that can be treated only by CRRT. The treatment should be started early, as it is necessary to avoid further damages or other vital function disturbances due to the loss of exocrine renal function.
