Neurogenic pulmonary oedema

Abstract

Two young patients with head injuries subsequently developed neurogenic pulmonary oedema. The origin and pathways of the reflex response to cerebral trauma are discussed, with emphasis on the role of raised intracranial pressure and the sympathetic division of the autonomic nervous system in precipitating movement of systemic circulatory volume into the pulmonary circulation. Therapeutic measures are discussed which correct the progression of this condition by reducing intracranial pressure and blocking the systemic effects of autonomic reflex activity. This leads to the basis of a simple regime to treat future cases.
