SEVERE HEAD-INJURY - PREHOSPITAL AND EMERGENCY DEPARTMENT MANAGEMENT

Head trauma causes approximately 75,000 deaths each year in the United States. Both hypoxia and hypovolemia are individual predictors of poo r outcome in the patient with severe head trauma. Management begins in the field and is focused on ensuring oxygenation and maintaining a bl ood pressure that supports cerebral perfusion. In the trauma center, i ntracranial pressure monitoring may be helpful in guiding the manageme nt of increased intracranial pressure. Mannitol, given in intermittent bolus infusions, is the therapy of choice for increased intracranial pressure. Hyperventilation has been shown to decrease cerebral perfusi on and should be avoided; it is a temporizing procedure that is reserv ed for those cases that demonstrate signs of increased intracranial pr essure pending initiation of other therapies.
