Pulmonary Complications Associated with Head Injury

More than 30,000 Americans die each year as a result of head injuries. Although destroyed brain cannot be replaced, intensive care can preserve surviving tissue and improve the prognosis of the 50% who are expected to recover. Atelectasis, aspiration, barotrauma, pneumonia, and other respiratory complications are common and lead to further morbidity and mortality. Even patients whose chest radiographs are normal are often hypoxemic. Careful airway control and arterial blood gas management are essential if the disastrous consequences of brain ischemia and intracranial hypertension are to be avoided.
