[Bilateral pulmonary infiltrations in patients admitted to an intensive care unit].

Diffuse pulmonary infiltrates are commonly found in hypoxic respiratory failure. We have reviewed 16 patients admitted to our medical intensive care unit over a period of 21 months, of whom seven died in hospital. Only patients requiring ventilatory support (CPAP or mechanical ventilation) for respiratory failure due to non-cardiogenic causes were included. All patients met the criteria for the diagnosis of ARDS. Three patients suffered from Wegener's granulomatosis, three from Pneumocystis carinii pneumonia, three from bacterial pneumonia, and two from pneumonia. Staphylococcal septicemia, SLE, sarcoidosis, cancer-associated hemolytic-uremic syndrome and ARDS of unknown etiology were each found in one patient. We discuss diagnosis and treatment of such patients on the basis of our experience.
