Abstract
Our 18-year old female patient suffered from microscopic polyangiitis. After invasive diagnostics, a diffuse alveolar hemorrhage occurred, leading to acute lung failure. In spite of differential ventilation, respiratory insufficiency and lactate-acidosis increased quickly. Due to the massive hemorrhage, a pumpless extracorporeal lung assist was implanted and, after six hours, low-dose heparinization was started. In response to this therapy, hypercapnia and acidosis improved quickly and were completely eliminated within 24 hours. Simultaneously, treatment with prednisolon and cyclophosphamid was started. After 7 days, the patient's conditions allowed weaning from the pumpless extracorporeal lung assist and after 9 days she was extubated.
In conclusion, the pumpless lung assist was shown to be a very practical option to treat the most serious forms of hypercapnia, especially for patients disposed to diffuse bleeding.
