The beneficial effects of inhaled nitric oxide in patients with severe traumatic brain injury complicated by acute respiratory distress syndrome: a hypothesis.
The Iraq war has vividly brought the problem of traumatic brain injury to the foreground. The costs of death and morbidity in lost wages, lost taxes, and rehabilitative costs, let alone the emotional costs, are enormous. Military personnel with traumatic brain injury and acute respiratory distress syndrome may represent a substantial problem. Each of these entities, in and of itself, may cause a massive inflammatory response. Both presenting in one patient can precipitate an overwhelming physiological scenario. Inhaled nitric oxide has recently been demonstrated to have anti-inflammatory effects beyond the pulmonary system, in addition to its ability to improve arterial oxygenation. Furthermore, it is virtually without side effects, and can easily be applied to combat casualties or to civilian casualties. ⋯ Inhaled nitric oxide therapy in traumatic brain injury patients with acute respiratory distress syndrome could result in increased numbers of lives saved, decreased patient morbidity, decreased hospital costs, decreased insurance carrier and government rehabilitation costs, increased tax revenue secondary to occupational rehabilitation, and families could still have their loved ones among them.

Mechanical ventilation in neurologically injured patients presents a number of unique challenges. Patients who are intubated due to a primary neurologic injury often experience respiratory phenomena secondary to that injury, including elevation of intracranial pressure (ICP) in response to mechanical ventilation and variations in respiratory patterns. ⋯ Balancing the need to maintain brain oxygenation and control of ICP can be complicated by the effects of ventilator management on ICP. We will examine the consequences of ventilator management as they relate to parameters that affect ICP and brain oxygenation in patients who have neurologic injury.
