Postburn respiratory injury.

A common and frequently overlooked concommitant of burn injury is postburn pulmonary damage. The lesion may be secondary to inhalation or mechanical obstructive or toxic problems; or it may be associated with indirect damage from hypovolemia, shock, central nervous system disturbances or drugs. Therapy comprises establishing a clear airway; administration of sufficient humidity and oxygen to maintain adquate arterial pO2; sequential pO2 monitoring; surface decompression of the thorax; systemic antibiotics and sequentially increasing--and later decreasing--airway support. The diagnosis of postburn pulmonary injury is clinical. Aggressive, sequential management of the patient, supported vigorously by laboratory evaluation, is essential.
