[Control of the therapeutic heparin dosage in platelet rich citrate plasma after protamine neutralization].
A laboranalytical method for estimating the anticoagulative effect of therapeutic heparin doses based on coagulation physiology is presented. Corresponding to our expectation this method is overcome by the direct measuring heparin with chromogenic substrates. On the other hand there are some advantages against the often practically used prolongation of PTT. By neutralisation of the heparin influence with protamine sulphate it is possible to discriminate between the heparin effect and additional disturbances in consequence of deficit in a coagulation factor. An absence of the heparin effect should always lead to the use of an antithrombin III assay.
