[Technic and indication for controlled ultrafiltration].

The isolated ultrafiltration with commercial dialysators gives a possibility of the massive dehydration in a short time without disturbing the well-being of the patient. If in patients undergoing a dialysis a following haemodialysis (sequential ultrafiltration haemodialysis) is necessary, particularly in patients with acute complications hypotonic circulatory conditions may develop. An infusion of a fourfold concentrated human dry plasma during the ultrafiltration may prevent these hypotensions, since reduction of osmolality and losses of circulation-effective substances are prevented during haemodialysis. With the help of this kind of treatment conditions of hyperhydration of different genesis may be removed also in patients with inclination to hypotension.
