Edema pulmonar neurogênico: relato de dois casos

Abstract

Neurogenic pulmonary edema is a rare and serious complication in patients with head injury. It also may develop after a variety of cerebral insults such as subarachnoid hemorrhage, brain tumors and after epileptic seizures. Thirty six patients with severe head injury and four patients with cerebrovascular insults treated in Intensive Care Unit of HC-UNICAMP from January to September 1995 were evaluated. In this period there were two patients with neurogenic pulmonary edema, one with head injury and other with intracerebral hemorrhage. Diagnosis was made by rapid onset of pulmonary edema, severe hypoxemia, decrease of pulmonary complacence and diffuse pulmonary infiltrations, without previous history of tracheal aspiration or any other risk factor for development of adult respiratory distress syndrome. In the first case, with severe head trauma, neurogenic pulmonary edema was diagnosed at admission one hour after trauma, associated with severe systemic inflammatory reaction, and good outcome in three days. The second case, with hemorrhagic vascular insult, developed neurogenic pulmonary edema the fourth day after drainage of intracerebral hematoma and died.
