[Respiratory disorders in patients with acute arterial occlusion of legs and ischemic syndrome].

The analysis of postoperative period in 325 patients with acute lower extremities' arterial obstructions and in 100 patients with chronic obstructive diseases of the lower extremities' arteries has been done. Specific features of the external respiratory function, acid-base balance and arterial blood gases were tested in 70 patients. In patients with the acute ischemia of lower extremities the rate of pulmonary complications in the early postoperative period was 64%, in patients with chronic occlusive diseases--42%.

[Effects of intravascular laser irradiation of blood on erythrocyte stereo-ultrastructure in the treatment of generalized suppurative peritonitis].

The authors analysed the course and the results of examination of peripheral blood in dynamics and study of red cell stereo-ultrastructure in dynamics before and after sessions of intravascular laser irradiation of blood (ILIB) and treatment in 120 patients with peritonitis, in 60 of them ILIB was applied in the complex of intensive therapy (main group). The control group was made up of 60 patients. The studies showed a favorable curative effect of ILIB: the morphological characteristics of red cells and peripheral blood in patients with peritonitis improves.

[The pulmonary distress syndrome during acute arterial occlusion of the lower extremities].

After surgery for acute arterial occlusion in the lower extremities 59 patients have developed tachypnea, respiratory alkalosis and arterial hypoxemia. These symptoms persisted over the whole postoperative period. In 66% of dead patients pulmonary changes have been observed and only in 34% of patients who died suddenly the lungs were unaffected.

[Pathology of the lungs in patients with acute arterial obstruction in the lower extremities].

The course of the early postoperative period has been analysed in 325 patients with acute thrombosis and embolism; the results of 104 autopsies have been reviewed and macro- and microscopic lung studies have been performed using light microscopy. It has been established that broncho-pulmonary complications are most frequently encountered in the early postoperative period. Morphological changes in the lungs are proportional to the duration and severity of acute ischemia.

[Changes in erythrocytes, acid-base equilibrium and blood gases in acute thromboembolism of the aorta and major arteries].

The article deals with the analysis of the course of the disease, the postoperative period, and complications in 293 patients and the results of study of the red cell ultrastructure and the acid-base equilibrium and blood gas composition in 33 patients with thrombosis and embolism of the main limb arteries. It was shown that the blood, its red cells, is the system which is mainly affected by endotoxins and high concentrations of biologically active substances occurring in the blood flow. According to the form of the red cells (normocytes, echinocytes, spheroechinocytes) and the quantitative relationship the depth of the pathological process can be judged.
