Abstract

The aim is to evaluate the state of hemostasis and liver system, as well as nitrogen and protein metabolism on the model of direct lung damage in the experiment on 50 mongrel female SD rats eighing 200-250 g. In the experiment, acute respiratory distress syndrome was modeled by a single intratracheal injection of acidine-pepsin with pH-1.2 in the amount of 0.1 ml per animal in the control group (n = 25) and the modeling group (n = 25). Researchers sampled the material after 1, 3, 5, 7, and 14 days  terminal points). Lung damage was assessed by light microscopy on histological preparations. Researchers analyzed serum for biochemical studies, collecting samples from the heart in tubes containing 3.8% sodium citrate at a ratio of 1:9 for coagulation tests in tubes with activator. During the experiment, haemostasis system disturbances accompanied acute respiratory distress syndrome formation, resulting in reduced prothrombin and activated partial thromboplastin time, elevated fibrinogen concentration, and decreased antithrombin III levels. Moreover, it led to the development of multi-organ failure, as evidenced by the recorded deviations of biochemical and coagulation parameters. The combination of multiple pathological processes within a syndrome is the greatest challenge in the treatment process. The development of experimental models to identify the interrelationship of the largest number of significant systems will allow the creation of an optimal model reproducing the entire symptom complex for the development of new protocols to treat acute respiratory distress syndrome.
