Anesthesiology. 1995 Oct;83(4):679-89; discussion 29A-30A.


Parameters of coagulation that are indicators of thrombin generation and activity (F1+2 prothrombin fragments, thrombin-antithrombin III complex, and fibrin monomers), parameters of fibrinolysis (D-dimers), aprotinin, and heparin plasma concentrations were measured.

Three different clotting times, the celite-based ACT, the kaolin-based activated coagulation time (AKT) and the high-dose thrombin time (HITT), were compared in a prospective, double-blind, placebo-controlled study of 20 patients who were to undergo cardiopulmonary bypass.

This was compared to a standard Hemochron ACT assay using diatomaceous earth.
With the TEG assay, the direct thrombin activator, ecarin, was used to initiate coagulation and measured as the reaction time.

Because AT is variably, and sometimes extensively, reduced in many patients before and during CPB, AT supplementation in these patients might be useful in reducing excessive thrombin-mediated consumption of labile hemostatic blood components, excessive microvascular bleeding, and transfusion of blood products.

The TFPI/FXa complex then subsequently binds with TF/activated factor VII (FVIIa) complex, ultimately inhibiting thrombin generation.

The main properties of each adsorbant are listed as well as several applications such as: selective adsorption of fibrinogen, separation between fibrinogen and factor VIII, separation of factor II from the other components of the prothrombin complex.
