title: Hemodynamic management of brain-injured patients.
abstract: Head-injured patients require maintenance of systemic hemodynamics as well as attention to cerebral hemodynamics. Most head-injured patients have increased metabolic oxygen consumption, mild hypertension, and increased cardiac indices. Assessment of regional perfusion, difficult in many patients, includes monitoring of urinary output. In head-injured patients, especially those with multiple injuries, the two most important goals are preservation of cerebral perfusion pressure (mean arterial pressure minus intracranial pressure) and maintenance of systemic oxygen availability (cardiac index times arterial oxygen content).
