Analysis of bronchoalveolar lavage fluid (Balf) from patients with adult respiratory distress syndrome (ARDS)
- Univ. of Cincinnati College of Medicine, Cincinnati, OH (United States)
The pathogenesis of ARDS is largely unknown, but many factors are known to predispose one to ARDS: sepsis, aspiration of gastric contents, pneumonia, fracture, multiple transfusions, cardiopulmonary bypass, burn, dissemination intravascular coagulation, pulmonary contusion, near drowning, and pancreatitis. ARDS is characterized by severe hypoxemia, diffuse pulmonary infiltrates, and decreased pulmonary compliance. Current treatment methods still result in 50% mortality. Studies are underway at the University of Cincinnati to determine if treatment with a synthetic pulmonary surfactant, Exosurf{sup {reg_sign}} (contains dipalmitoyl phosphatidyl choline, Burroughs-Wellcome), improves the prognosis of these patients. BALF from these patients, before and after treatment, was analyzed to determine if the treatment resulted in an increase in disaturated phospholipids (surfactant phospholipids) in the epithelial lining fluid and if the treatments reduced the concentration of markers of inflammation and toxicity in the BALF. This study indicates that the method of administering Exosurf{sup {reg_sign}} did not lead to an increase in surfactant lipid or protein in the bronchoalveolar region of the respiratory tract.
