[Three cases of chronic respiratory failure].

Three patients with chronic respiratory failure of various etiology, who have (had) been in the hospital for some years, were presented. The case 1 is male and was 57 years old on admission. He has been suffered from right thoracic emphysema from October '83, which is under chronic infection of Pseudomonas aeruginosa, with bronchial fistula and aortic valve insufficiency. His pulmonary function is severely restrictive and the grade of his dyspnea has been V of Hugh-Jone's criteria and he is now unable to leave from bed. The case 2 is male and was 41 y.o. on admission. He has been ill with diffuse cystic bronchiectasis from 33 y.o. and bronchorrhea (greater than 200 ml/day) with chronic infection of Pseudomonas aeruginosa has been lasting and recurrent attacks of infection have progressively worsened of his pulmonary and cardiac functions. He is now indispensable to assist ventilation by artificial respirator every 2-3 days. The case 3 was male and 27 y.o. on admission. He had admitted because of severe dyspnea due to familial pulmonary fibrosis on August '86. His disorder had been progressive and resistant against repeated corticosteroid therapy. He died of respiratory failure at 30 years old. The transplantations of lung and heart-lung for critical patients with respiratory failure have been challenged in North America and Europe, but in Japan, many social and medical problems about transplantation have yet been unresolved. The indications for and against lung or heart-lung transplantation to these three patients was discussed with reference to English literatures.
