[Analysis of bronchoalveolar lavage fluid in a case of high altitude pulmonary edema].
A 29-year-old male climber developed high altitude pulmonary edema (HAPE), progressing from headache and dyspnea to disturbance of consciousness in the Japan Alps. He was admitted to Shinshu University Hospital. Physical examination on admission revealed a cyanotic patient with coarse crackles and wheezes in bilateral lungs. Chest X-ray film showed bilateral patchy infiltrates. Arterial blood gases indicated severe hypoxemia, and respiratory alkalosis; pH 7.452, PO2 35.5 Torr, PCO2 31.6 Torr. Right heart catheterization showed noncardiogenic pulmonary edema, analysis of bronchoalveolar lavage (BAL) fluid was as follows; cells 2.05 x 10(5)/ml (alveolar macrophages 61.5%, neutrophils 25.5%, lymphocytes 13.0%), protein concentration 91 mg/dl. Cellular and protein analysis of BAL has been shown to be of value to clarify the pathogenesis of the permeability edema in patients with HAPE.
