This report presents a patient who developed fulminant pulmonary edema as a complication of an acute subarachnoid hemorrhage. Hemodynamic evaluation revealed low-normal pulmonary arteriolar resistances. Endobronchial fluid was freely suctioned from the patient over a two-day period and had a colloid osmotic pressure and protein content equal to the patient's plasma throughout the entire course. These findings suggest that neurogenic pulmonary edema in this patient was related to increased capillary permeability and may occur independent of pulmonary hemodynamics.

The effect of furosemide in the intraoperative reduction of intracranial pressure was measured in 25 patients undergoing the operative repair of a ruptured intracranial aneurysm. Seven patients with similar intracranial lesions served as controls. ⋯ These changes are significant at the P less than 0.005 confidence level, whereas changes in mean arterial pressure, mean arterial pCO2, and base line arterial pCO2 were statistically insignificant. This study suggests that intravenous furosemide is a quick, dependable, and effective mechanism for the intraoperative reduction of intracranial pressure in the postsubarachnoid hemorrhage aneurysm patient.
