HEMODYNAMIC CHANGES DUE TO PULMONECTOMY (EXPERIMENTAL STUDY)
Relevance. Currently, the main directions of treatment of postoperative disorders after pulmonectomy are infusion-transfusion maintenance of hemodynamics, antibacterial chemoprophylaxis of infectious complications and perioperative nutritional support. Analysis of the literature data showed that the severity and originality of the course of the postoperative period is determined by hemodynamic disturbances and the function of vital organs, which determines the relevance of this problem. Purpose. In this study, we studied hemodynamic status indicators with subsequent pulmonectomy in experimental animals. Materials and methods. The study was conducted on 12 laboratory animals (rabbits). The state of the pulmonary artery, pulmonary tissue and portal blood flow was studied by radioisotope method from the moment of pulmonary artery ligation up to one month after pulmonectomy. Hemodynamics was evaluated after 1 and 3 hours, 1; 3 and 7 days and a month later. Results. Removal of one lung significantly disrupts the hemodynamics of the remaining lung, which occurs during pulmonary artery ligation. Violation of pulmonary blood flow, in turn, leads to a violation of the portal-venous blood flow that occurs during blinking of the bronchi, and a violation of local blood flow is recorded 3 hours after pulmonectomy.
