STUDY OF HISTOLOGICAL FEATURES OF LIVER REACTION USING NEW SAMPLES OF POLYMERIC HEMOSTATIC MATERIALS IN THE EXPERIMENT IN VIVO

Abstract

Abdominal trauma in 26.7-40.8% of cases is accompanied by trauma of parenchymal organs. The condition of the patient with liver injury in 75% of cases is complicated by the development of hemorrhagic shock. In surgery, to achieve local hemostasis, the most promising method is the topical use of application hemostatic agents, while the composition of such funds determines the effectiveness of hemostasis.
 The aim of the study is to assess the histological characteristics of the liver using new samples of polymeric hemostatic materials in the experiment in vivo.
 Materials and methods. As research material was used hemostatic sponge based on natrocarbonatite (Na-CMC) (developed jointly with Linteks, Russia. Saint-Petersburg.) In the experimental groups of laboratory animals under general anesthesia produced a median laparotomy and simulated planar surface injury to the liver. Parenchymal bleeding was stopped by applying application hemostatic materials. An autopsy of the injured area of the liver was performed together with an implanted hemostatic agent. The thickness of the capsule, the size of the Central veins of the liver, the number of dual-core hepatocytes, the size of hepatocytes and their nuclei were measured.
 Results. The indicator of the area of hepatocytes of groups No. 4 and No. 5 are as close as possible to group No. 1 indicators. Similar to the area of hepatocytes, difference of the area of their kernels in groups No. 6, No. 7 are statistically not significant in comparison with group No. 1. In groups No. 6 and No. 5 the area of kernels is authentically increased, but does not reach values of control group. The greatest statistically significant increase in thickness of the capsule in comparison with group No. 1, group No. 2 and No. 3 was observed in group No. 4. The area of the central vein is authentically increased in comparison with control group in groups No. 2, No. 3 and No. 6. The number of two-nuclear hepatocytes in comparison with norm, group No. 4 and group No. 1 is reliable above in groups No. 6 and No. 7.
 Conclusion. Histologic reorganizations, changes of morphological structure in places of a trauma and implantation of the tested samples are less expressed when using haemo static implants of experimental groups No. 3-№6 (styptic local means on the basis of Na-KMTs with addition of aminocaproic, acetilsalicylic and aminoacetic acids).
