Difficulty: MediumInitial Stabilization and Triage

A 42-year-old woman is evaluated in the emergency department after being extracted from a burning residential building. Firefighters report she was found trapped in a closed, smoke-filled room. On arrival, she is awake and alert but complains of severe pain from burns on her torso. The patient has a notably harsh, raspy voice and is coughing up carbonaceous sputum. Vital signs show a temperature of 37.1°C (98.8°F), blood pressure of 135/85 mmHg, pulse of 110/min, and respirations of 24/min. Oxygen saturation is 98% on a 100% non-rebreather mask. Physical examination reveals singed nasal hairs, soot deposited in the posterior oropharynx, and partial-thickness burns covering approximately 18% of her total body surface area. Which of the following is the most appropriate next step in management?

  1. Secure the airway with an endotracheal tubeAnswer
  2. B
    Order an immediate portable chest radiograph to evaluate for pulmonary edema
  3. C
    Draw blood for an arterial blood gas and carboxyhemoglobin level
  4. D
    Initiate therapy with nebulized bronchodilators and intravenous methylprednisolone
  5. E
    Begin aggressive intravenous fluid resuscitation using the Parkland formula

Answer

Secure the airway with an endotracheal tube
The correct answer emphasizes that in trauma and burn resuscitation, the airway is the absolute first priority. This patient presents with multiple clinical indicators of thermal inhalation injury, including a hoarse voice, carbonaceous sputum, and soot in the posterior oropharynx. Thermal injury to the upper respiratory tract can cause massive mucosal edema that progresses rapidly, leading to complete upper airway obstruction. Because swelling can make later intubation extremely difficult or impossible, early prophylactic endotracheal intubation is required, even if the patient is currently alert and oxygenating well.

Step-by-Step Solution

1
Identify the primary clinical threat based on the patient's presentation.
The patient has hoarseness, carbonaceous sputum, singed nasal hairs, and soot in the oropharynx after a closed-space fire.
These findings are highly specific for thermal injury to the upper airway.
2
Determine the pathophysiological consequence of thermal injury to the upper airway.
Thermal injury causes massive, rapid fluid shifts resulting in progressive upper airway edema.
Heat damage to the mucosal tissues leads to sudden swelling that can completely occlude the airway within minutes to hours.
3
Select the appropriate intervention sequence according to Advanced Trauma Life Support (ATLS) principles.
Airway stabilization must precede breathing, circulation (fluids), and diagnostic testing.
Failure to prophylactically secure the airway early may result in a 'cannot intubate, cannot ventilate' scenario once profound edema develops.

Key Concept

Patients with signs of thermal inhalation injury (e.g., hoarseness, singed facial hair, carbonaceous sputum, soot in the oropharynx) require prompt prophylactic endotracheal intubation to secure the airway before progressive edema makes intubation impossible.
