title: The clinical and physiological effect of whole-lung lavage in pulmonary alveolar proteinosis: a ten-year experience.
abstract: We have utilized whole-lung lavage in the successful treatment of 18 patients with pulmonary alveolar proteinosis. Our ten-year experience includes serial evaluations of patients with disabling lung dysfunction who had a total of 49 whole-lung lavages under general anesthesia. Clinical and physiological responses were documented both before and after each lavage. There were no complications or deaths. All patients were radiographically, physiologically, and symptomatically improved within hours after the procedures. Five patients required from two to four repeat lavages one to three years later. The treatment of this disorder has included a wide variety of techniques. We attribute our results to the use of a lung lavage technique that includes: (1) unilateral whole-lung lavages at two to three day intervals; (2) isotonic saline as the lavage solution; (3) use of a mechanical chest percussor during lavage; and (4) measuring the total thoracic compliance of each side in the immediate postlavage period as a guide for extubation. We conclude that whole-lung lavage is a safe, highly effective, repetitively applicable treatment for pulmonary alveolar proteinosis.
