Hemostasis in Liver Injuries: An Experimental Study

Introduction. Bleeding in liver injuries is observed during natural disasters, massive injuries, in military field conditions and under other circumstances. The vital need for surgical treatment in these cases is obvious. As a rule, time for assistance is limited, and operations are performed by surgeons who do not have sufficient experience. Intraoperative hemostasis methods are not always effective. The search for intraoperative hemostasis methods has not stopped for many decades. Experimental study of the effect of new agents that allow for reliable hemostasis in liver damage is relevant for medical science and practice.Materials and methods. The experimental study included 116 white Wistar rats of both sexes weighed 230 25 g and 30 Chinchilla rabbits of both sexes weighed 2.5-3.5 kg. The following parameters were identified in experiments in vivo: the duration of bleeding in simulated liver injury without the use of hemostatics and with the use of alufer and viscostat preparations. A morphological study of the regenerative process in the liver was carried out on the 1st - 14th day after the injury. The biopsy material was fixed in 10% formalin solution. Staining of histological sections was carried out with hematoxylin and eosin, as well as Prussian blue (according to Max Perls) to detect iron compounds in tissues.Results. It was revealed that the implementation of hemostasis with the use of the alufer preparation is accompanied by a decrease in circulatory disorders (edema, hemorrhages); characterized by a more pronounced formation of the connective tissue in the area of drug ​​application, which is partially retained (taking into account the time interval of the study) at the site of application.
