[Laboratory monitoring of recombinant factor VIIA effects].

Recombinant activated factor Vll originally proposed to prevent and arrest bleedings in patients with the inhibitory form of hemophilia has been shown to be a universal hemostatic agent that is effective in arresting and preventing a broad spectrum of spontaneous and postoperative hemorrhages. Procedures for monitoring the action of this agent on the hemostatic system have not been studied so far. The paper presents the results of a study of various parameters of the hemostatic system in patients with profuse hemorrhages before and after the use of recombinant activated factor VII. It has been ascertained that monitoring of the pharmacokinetics of the agent can be achieved when the prothrombin test with bovine thromboplastin is carried out.
