Neurogenic pulmonary edema in childhood.

Three patients presenting with pulmonary edema associated with head trauma and increased intracranial pressure are described. Pulmonary edema is a clearly recognized complication of head trauma; the pathogenic mechanisms appear to be regulated by increased intracerebral pressure, sympathetically induced vascular hypertension, and increased pulmonary capillary permeability. If there is evidence that neurogenic pulmonary edema is the underlying etiology, therapeutic modalities should be directed at reducing intracranial pressure and strict attention paid to the interaction between intrathoracic and intracranial pressures in order to avoid the high mortality rate associated with this condition.
