Difficulty: MediumInitial Stabilization and Triage

A 45-year-old man is brought to the emergency department by ambulance after being rescued from a closed-space house fire. Paramedics report the patient was trapped in a smoke-filled room for approximately 10 minutes. His past medical history is significant for hypertension. On arrival, the patient is awake but severely agitated. He has full-thickness and deep partial-thickness burns over his anterior chest, abdomen, and bilateral upper extremities. Physical examination reveals singed nasal hair, soot in the oropharynx, carbonaceous sputum, and a hoarse voice. Breath sounds are present bilaterally with diffuse expiratory wheezes. Vital signs are temperature 37.1°C (98.8°F), pulse 122/min, blood pressure 118/76 mmHg, respiratory rate 28/min, and oxygen saturation 93% on a non-rebreather mask at 15 L/min. Which of the following is the most appropriate initial step in the stabilization of this patient?

  1. Perform endotracheal intubationAnswer
  2. B
    Initiate intravenous fluid resuscitation with lactated Ringer solution
  3. C
    Obtain an arterial blood gas with carboxyhemoglobin level
  4. D
    Obtain a stat portable chest radiograph
  5. E
    Perform flexible fiberoptic bronchoscopy

Answer

Perform endotracheal intubation
The correct action is to perform endotracheal intubation. This patient presents with a classic scenario of severe thermal and inhalation injury from a closed-space fire. The presence of a hoarse voice, singed nasal hair, soot in the oropharynx, and carbonaceous sputum strongly indicates a supraglottic thermal injury. This type of injury causes rapid and progressive edema of the upper airway, which can lead to complete airway obstruction. According to Advanced Trauma Life Support (ATLS) principles, securing the airway is the highest priority. Prophylactic intubation must be performed immediately upon recognizing these signs, as waiting until the patient develops stridor or severe respiratory distress often makes intubation impossible, necessitating an emergency surgical airway.

Step-by-Step Solution

1
Evaluate the primary survey (ABCs) in a trauma/burn patient.
The patient exhibits singed facial hair, carbonaceous sputum, hoarseness, and was in a closed-space fire.
These findings are classic clinical indicators of a severe upper inhalation injury with a high risk of rapid, progressive airway edema.
2
Determine the immediate intervention required based on the primary survey.
The airway must be secured definitively with endotracheal intubation.
If intubation is delayed, upper airway edema can rapidly progress, rendering later attempts at intubation impossible and necessitating a surgical airway.
3
Sequence subsequent diagnostic and therapeutic steps.
Fluid resuscitation, laboratory diagnostics, and imaging are deferred until the airway is secure.
Airway stabilization takes absolute precedence over all other interventions.

Key Concept

In patients with significant thermal burns and clinical signs of inhalation injury (e.g., hoarseness, carbonaceous sputum, singed facial hair), early prophylactic endotracheal intubation is the single most urgent step to secure the airway before progressive edema makes intubation impossible.
