[Relationship of disorders of transcapillary fluid exchange in the lungs and respiratory mechanics in postoperative pulmonary complications].

The central hemodynamics, external respiration function, and transcapillary liquid exchange in the lungs were assessed in 23 patients operated on the lungs and in 18 subjected to open heart surgery. The content of extravascular liquid in the lungs was increased during the first hours postoperation in the patients with a complicated course of the postoperative period, in contrast to those with an uneventful course thereof. Disorders of transcapillary liquid exchange did not depend on the status of the central hemodynamics and probably reflected the increased permeability of the alveolocapillary membrane.
