Randomized Controlled Trial Comparative Study Clinical TrialLeukocyte and platelet depletion with a blood cell separator: effects on lung injury after cardiac surgery with cardiopulmonary bypass.
This study was undertaken to assess the effects of leukocyte and platelet depletion on postoperative lung injury in 42 patients who underwent heart operations. Blood was serially sampled before, during, and after cardiopulmonary bypass, and leukocyte count, platelet count, and thromboxane B2 6-keto-PGF1 alpha, leukocyte elastase, thrombin-antithrombin III complex, and D-dimer levels were determined. Postoperative respiratory function was assessed based on analyses of oxygenation and carbon dioxide elimination. ⋯ The elimination of carbon dioxide was lower in the experimental group. Depletion of leukocytes and platelets reduced respiratory dysfunction after heart operations with cardiopulmonary bypass. It was particularly effective in patients with a low preoperative oxygenation capacity and in those for whom an extended period of cardiopulmonary bypass was required.

Clinical TrialInitial experience with partial liquid ventilation in pediatric patients with the acute respiratory distress syndrome.
Liquid ventilation with perfluorocarbon previously has not been reported in pediatric patients with respiratory failure beyond the neonatal period. We evaluated the technique of partial liquid ventilation in six pediatric patients with the acute respiratory distress syndrome of sufficient severity to require extracorporeal life support (ECLS). ⋯ Perfluorocarbon may be safely administered into the lungs of pediatric patients with severe respiratory failure on ECLS and may be associated with improvement in gas exchange and pulmonary compliance.

Comparative Study
Diagnostic imaging of idiopathic adult respiratory distress syndrome (ARDS)/diffuse alveolar damage (DAD) histopathological correlation with radiological imaging.
In ten patients with idiopathic adult respiratory distress syndrome (ARDS) who had histopathologically diffuse alveolar damage (DAD), and who did not have specific underlying diseases, we compared the histopathological findings with their radiographic images in order to study the detail analysis of radiographic images and the clinical courses. These patients were roughly classified as having the interstitial pneumonia dominant type (type IP) of idiopathic ARDS, in which alveolar septal thickening, alveolitis, or both were the predominant histological findings and images showed increasing attenuation of lung fields with small honeycomb lung, or the organizing pneumonia dominant type (type OP), in which organizing exudate predominantly filled the alveoli histologically and images showed consolidation shadows with some air. Hyaline membrane was seen very frequently in patients with a short clinical course, and in accordance with a longer clinical course, widespread fibrosis and honeycomb lung covered by organizing hyaline membrane was seen with both types. Patients with type OP in whom collapse of the normal pulmonary structure was less and for whom changes on radiographic images were larger seemed to respond relatively favorably to steroid treatment, as judged from pulmonary function and radiographic images.
