[Characteristics of hemodynamic and external respiratory function in patients with concomitant wounds of the heart and lung during early postoperative period].

The parameters of intracardiac hemodynamics and external respiratory function (ERF) were studied by echocardiography and computed spirography with pneumotachometry in 123 patients with punctured and lacerated wounds of the chest in the early postoperative period. All the patients were divided into 6 groups according to the pattern of injuries. Group 1 included 25 patients with chest wound without organ damages; Group 2 comprised 42 patients with wound of the lung; Group 3 consisted of 22 patients with wound of the left ventricle (LV); in Group 4 there were 11 persons with wound of LV and the lung; Group 5 included 8 victims with wound of the right ventricle (RV); and Group 6 comprised 15 patients with wounds of the lung and RV. One- and five-day follow-ups revealed the most pronounced disorders of intracardiac hemodynamics and ERF in patients with concomitant wound of the lung and RV (Group 6). At the same time it was found that when wounds of the lung were concomitant with those of the heart, there was discoordination of RV and LV work with decreased volumetric blood flow along the pulmonary artery. These impairments also persisted by day 5 of the moment of wound. By that time there were positive hemodynamic and ERF changes in the other groups.
