Synonym: smoke inhalation injury
Injury to the oropharynx, nasopharynx, trachea, bronchi, or lungs from exposure to smoke or heated gas. This injury is a potentially life-threatening complication of exposure to smoke and fire and is often present in those who have suffered facial burns; firefighters are esp. at risk. Early complications of inhalation injury include bronchospasm, airway edema, airway obstruction, and respiratory failure. Late complications include hospital-acquired pneumonias and other respiratory illnesses. Patients suspected of inhalation injury should be promptly and repeatedly assessed to make certain they have an open airway. Emergent tracheal intubation is used to prevent respiratory failure. See: carbon monoxide
Patients who have suffered smoke inhalation injury may complain of dyspnea, cough, and black sputum. Stridor may be present if the upper airway is narrowed as a result of inflammation. Confusion may occur if carbon monoxide poisoning is also present.
