[Optimizing dialysis treatment in acute renal failure].

The empirical dialysis therapy of acute renal failure should be replaced by modern scientific methods of treatment. The classic indications for hemodialysis are hyperkaliemia, hyperhydratation, acidosis and uremia. While previously a dialysis was indicated in a concentration of blood urea nitrogen of more than 70 mmol/l today a serum level of 30 mmol/l is recommended. By the kinetic urea-modelling an individualized and effective dialysis-guidance is possible. The important data may be determined by a simple computer program in few seconds.
