Smoke Inhalation and Airway Management at a Regional Burn Unit

Abstract

Victims of smoke inhalation with and without burns and burn patients with respiratory insufficiency for reasons other than smoke at a regional burn unit are profiled in terms of age, burn size, length of stay, and mortality. The diagnostic characteristics of patients with an inhalation injury (N = 108) are listed; 7% of all patients (N = 52) have known smoke exposure with equivocal evidence for injury to the airway or pulmonary parenchyma. The degree of respiratory (visceral) failure experienced by patients with inhalation injury is not uniformly severe. Many of the clues to this diagnosis are indirect and not always related to the severity of pulmonary injury. Timing and degree of visceral failure control the severity of the injury, which increases progressively from that in patients with a burn only (parietal injury) through those with a visceral injury only (smoke without burn), those with both smoke and burn, to those with a burn and uniformly severe respiratory failure on the basis of sepsis.
