[Respiratory disorders in patients with acute arterial occlusion of legs and ischemic syndrome].
Аннотация
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%. Thromboembolic complications caused by hypoxemia and blood rheology disorders were predominant. Ventilation disorders were of combined (restrictive-obstructive) nature, and are mostly expressed on the 1st-3d postoperative day. Their rate is corvelated with the level and duration of preoperative ischemia. The pulmonary gas exchange function was damaged, as shown by persistentin arterial blood hypoxemia present during all early postoperative period.
