"BIATRAVM" is a two-layer medium consisting of hemostatic collagen sponge and non-woven material lavsan, proven itself as a wound cover, stimulating regenerative processes and has good drainage properties. Experimental studies were conducted on 24 mongrel dogs of both sexes. All the animals were divided into 4 experimental series (6 animals in each group). In the first series after the injury was carried out modeling standard hemostasis by suture catgut, in the second – lavsan in the third for the application and plugging hemostatic sponge was used in the fourth – the biological atraumatic wound covering "BIATRAVM." The choice of means of comparison groups due to the fact that the literature is the most gut common suture in injuries of parenchymal organs, polyester is part of the "BIATRAVMA" as a basis and a hemostatic sponge and a component of "BIATRAVMA" and frequently used hemostatic tool. Animals were derived from the experiment at 14 days. During the autopsy was evaluated pathological changes, severity of adhesions by the semantic differential in points (Lipatov, VA, 2001). For histological examination were taken of tissue surrounding the area and haemostatic suturing of (liver and spleen with soldered to the field of surgical intervention authorities).
Micromorphological study paintings done by light microscopy, digital fotoprotokolirovaniya using the method of morphometrics. The data obtained by standard methods of variation statistics. At autopsy in the field trauma of adhesions observed in all cases. In animals, the first series of pointed podpaivanie right lobe of the liver to the ventral wall. Liver injury in her place was fixed to the extensive fusion of planar bottom wall of the stomach. Pole of spleen were shrouded in place suturing tissue of the greater omentum. Spleen capsule coated with organizing fibrin. In all cases, the implementation of the hemostatic lavsan (second series) to the seams of the liver were fixed strands of the greater omentum.
