[Dynamics of the content of the pulmonary extravascular fluid during extracorporeal detoxication in critical state patients].

Time course of the content of interstitial, cellular, and total fluid in the lungs, of plasma osmolality and sodium concentration was studied in 20 patients with acute renal failure after repair surgery on the heart, thoracic and abdominal organs. Water balance of the lungs was studied by dissolution of electroimpedance indicators before and after removal of 2000-2500 ml of ultrafiltrate. Ultrafiltration of the blood in the course of hemodialysis (group 1) did not lead to a reliable reduction of the volume of intravascular fluid, whereas in group 2 a reliable reduction of the volume of interstitial fluid of the lungs by 34% and of the total liquid volume of the lungs by 29% occurred in the course of hemofiltration.
