Evaluation of the effectiveness of two-component sponge hectopative agents in acute in vivo experiment

Abstract

Currently, the effective stop of parenchymal bleeding that has developed for various reasons: trauma, planned and emergency surgical interventions, is a serious challenge for modern clinical surgery. Today, in the arsenal of doctors there are a large number of hemostatic agents that affect the coagulation process, however, local hemostatics attract much attention, since they have a significant advantage - the absence of a systemic effect on the blood coagulation system. The objective: in a comparative aspect, to study the effectiveness of two-component sponge hemostatic agents in the model of marginal liver resection in vivo. Materials and methods. In a comparative aspect, we studied the hemostatic activity of samples of local application hemostatic agents "TachoComb" (No. 1), prototypes of two-layer spongy hemostatic agents based on sodium salt of carboxymethylcellulose of various viscosities (No. 2), Surgicel Fibrillar. Rats under inhalation anesthesia underwent a median laparotomy, modeled marginal resection of the left lobe of the liver. Bleeding was stopped by applying the compared samples, while recording the amount of blood loss and bleeding time. In order to assess the statistical significance of differences between study groups, the Mann-Whitney test (p≤0.05) was used. Results. The minimum time to stop bleeding was noted in group No. 2. When comparing the volume of blood loss, no statistically significant differences were found. Conclusion. The use of samples of two-layer sponge hemostatic agents developed and tested in the experiment based on the sodium salt of carboxymethyl cellulose of various viscosities in stopping parenchymal bleeding in laboratory animals is not inferior to the currently used local hemostatics in terms of blood loss and statistically significantly accelerates the process of stopping bleeding.
