[The status of blood coagulation preparations within the scope of modern hemotherapy in surgical patients].

The risks and adverse reactions of fresh frozen plasma (FFP) and coagulation components have changed considerably in the last few years because of the spread of HIV on the one hand, and advances in the preparation and sterilization of coagulation components on the other. Therefore, the indication for FFP and the various coagulation components deserves constant consideration; this is the intention of this paper. FFP is still the therapeutic choice for the treatment of acquired (complex) plasmatic coagulation disorders, even though the (still) small risk of virus transmission in Middle Europe has to be taken into account. Coagulation components are primarily indicated in congenital (isolated) plasmatic coagulation disorders. Only in gross or very acute acquired coagulation disorders are coagulation components needed in addition to FFP. The same regimen is recommended for the use of antithrombin III (AT III) concentrates. In cases of acquired antithrombin deficiency, antithrombin III substitution is indicated only when the anticoagulation by heparin alone or in combination with FFP is insufficient or when the heparin doses required might entail an unexceptable bleeding risk, e.g. in simultaneous thrombocytopenia. Then AT III becomes an important therapeutic factor, especially in DIC. In addition, information regarding a rational and economic substitution of FFP and coagulation components is given, and other substitutes are mentioned which could possibly be used with less risk. Finally, the necessity for an adequate diagnostic procedure is emphasized. Close cooperation between the physicians in the clinics and in the department of transfusion medicine/hemostaseology reduces unnecessary and inadequate application of coagulation components. This also means an improvement of the patient's therapy.
