Methods to stop bleeding in spleen injuries depending on the nature of its damage in the experiment

Abstract

Objective . To substantiate and develop in the experimental conditions the methods of hemorrhage stopping in various wounds of the spleen depending on the nature and size of its damage. Material and methods : The experiments were carried out on 39 dogs. All operations were divided into 4 series. In the 1 st series models of the linear wounds of various length and depth were created; in the 2nd and 3rd — the models of the crushed and scalped wounds and the wounds after the planar and transverse resections; in the 4th series — the wound models after the splenic marginal and wedge resections. To close the presented wound models we used newly developed methods to stop bleeding. We used angiographic, physical, morphological and statistical methods of investigation at 1,3,5,7,14, 30, 90 days to assess their eff ectiveness. Results : The carried out researches have shown a good tightness of the investigated ways of the spleen wounds suturing. Morphological investigations at diff erent terms after the spleen operation revealed the absence of the signs of infl ammation and development of the secondary complications. There were no signs of the gastric fl ap rejection and blood oozing through its wall. Histological examination of the gastric fl ap revealed its good plastic and revascularizing properties. Conclusion : The developed ways of the bleeding stop have a reliable air-tightness that provides a reliable hemostasis and prevention of the development of secondary complications. The applied new principle of the wound closure depending on its size minimized using of both additional sutures and lining materials.
