Abstract

The systemic hemostatic and hemostasiological effects of intravenous injection of fibrin monomer (FM; 0.25 mg/kg) together with dabigatran etexilate (15-20 mg/kg) administration were compared to placebo (0.5 ml), prothrombin complex concentrate (d = 40 U/kg) and Eptacog alfa (activated) (d = 270 μg/kg) in a model of a controlled liver injury in 62 rabbits of the Chinchilla breed. It was found that FM, in comparison to placebo, reduced the volume of blood loss by 2.9 times and the rate of blood loss by 1.7 times, despite the dabigatran-induced hypocoagulation. Comparators did not show hemostatic efficacy. FM did not affect the parameters of the coagulogram (no visible hemostasiological effect), while the compared drugs showed some signs of increased hemostatic potential. It is assumed that the hemostatic effects of low, physiological doses of FM can be realized bypassing thrombin (factor IIa), which determines the need for further studies.
