[Individual dosage schedule of heparin therapy in chronic hemodialysis by analytic studies of blood coagulation].

In 20 patients analyses of the coagulation potential were performed in order to test the heparin dosage during chronic hemodialysis. The activated PTT is the most suitable laboratory test. Because of the individually different heparin consumption the control of PTT should performed in every dialysis patient after 90 minutes during the first 2-3 dialysis treatments. Thereby a lasting dosage schedule for each patient could be obtained. The heparin consumption per dialysis unit was approximately 5,200 (3,000-9,000) IU.
