[Effect of factors related to hemodialysis on certain blood-coagulation parameters].

It is reported on the changes of the thromboelastogramme, the fibrinogen level, the number of thrombocytes and the time of coagulation, which developed due to the haemodialysis with intermittent and regional heparinisation, as well as on the isolated effect of heparin, protamine and the heparin-protamine-complex. Among others the cause was discussed, why there are in some cases higher values of the time of coagulation in the patient than in the extracorporal circulation during haemodialysis. For practical reasons was emphasized that the protamine may also have a pronounced anticoagulation effect.
