ASSESSMENT OF BILIOSTATIC PROPERTIES OF MODERN TOPIC HEMOSTATIC MEANS USED IN HEPATIC SURGERY

Abstract

Aim. To assess the biliostatic properties of modern topic hemostatic means and the developed glue composition for medical purpose, used in hepatic surgery in experiment. Materials and methods. The studies, aimed at assessment of the properties of local hemostatic means, were carried out on Wistar rats weighing 178 ± 10 g. The device for determination of leak proofness of hepatic stump with hydropression technique was used. Comparative estimation of elasticity and adhesive strength of hemostatic means, using tension testing machine “REM-10”, was fulfilled. Original polyurethane glue for medical purposes was developed and studied. Results. The glue compositions “Bioglue”, hemostatic sponge “Tachocomb” and original polyurethane composition for medical purposes with adhesive strength > 600 Pa (mm H2O) ( p < 0.05) possess the best adhesive properties. It was established on the basis of experimental data that the glue composition “Bioglue” and polyurethane glue composition have a high adhesive strength, elasticity and resistance to hydropression. Conclusions. 1. Glue compositions possess higher adhesion and endure higher level of pressure as compared with sponges and plates. Original polyurethane composition has maximum adhesive strength, elasticity and hydropression resistance. 2. After application of original polyurethane glue composition on resected liver (in experiment), it is completely lysed in 30-35 days.
