Difficulty: HardInitial Stabilization and Triage

A 34-year-old industrial worker is brought to the emergency department by paramedics after being rescued from a chemical warehouse fire. The patient was trapped in an enclosed storage room for an unknown duration. En route, emergency medical services administered high-flow oxygen via a non-rebreather mask. On arrival, the patient is visibly agitated and confused. Temperature is 37.2°C (99.0°F), blood pressure is 84/50 mmHg, pulse is 138/min, and respiratory rate is 28/min. Oxygen saturation is 94% on 15 L/min of oxygen. Physical examination reveals significant soot accumulation in the oropharynx, singed facial hair, and noticeable hoarseness when the patient attempts to speak. There are widespread circumferential full-thickness burns involving both lower extremities, and partial-thickness burns extending across the anterior torso. Distal pulses in all extremities are palpable and symmetric. Which of the following are the most appropriate immediate steps in management? (Select two)

Answer

Endotracheal intubation and placement of two large-bore peripheral intravenous catheters.
The correct immediate steps are securing the airway and establishing vascular access. This patient presents with classic signs of impending airway loss due to inhalation injury (enclosed space fire, soot in the oropharynx, singed facial hair, and hoarseness). Thermal injury to the upper airway causes progressive, rapid-onset edema; waiting for stridor or complete obstruction makes intubation exceedingly difficult or impossible. Therefore, prophylactic endotracheal intubation is mandatory. Concurrently, the patient is in profound shock (hypotension, tachycardia) resulting from both vasodilation and massive third-spacing of fluids typical of extensive thermal injuries. Placement of two large-bore peripheral intravenous catheters is required immediately to initiate aggressive fluid resuscitation (e.g., Parkland or modified Brooke formula). Both interventions represent the 'A' and 'C' of primary trauma stabilization and must be initiated simultaneously.

Step-by-Step Solution

1
Evaluate the airway based on the mechanism of injury and physical exam findings.
The patient has a history of enclosed space fire exposure, hoarseness, singed facial hair, and carbonaceous sputum.
These findings are highly specific for thermal and chemical inhalation injury, which rapidly causes supraglottic edema and complete airway obstruction.
2
Assess the patient's hemodynamic status (circulation).
The patient exhibits severe hypotension (84/50 mmHg) and tachycardia (138/min).
Extensive burns cause massive capillary leak and profound hypovolemic/distributive shock requiring immediate and aggressive fluid resuscitation.
3
Prioritize initial interventions according to Advanced Trauma Life Support (ATLS) principles.
Airway protection and circulatory support must occur simultaneously and before diagnostic tests or definitive burn care.
Failure to address the ABCs (Airway, Breathing, Circulation) first leads to preventable morbidity and mortality.

Key Concept

In patients with severe burns and signs of inhalation injury, initial stabilization strictly prioritizes immediate airway protection (intubation) and circulatory support (large-bore intravenous access and fluid resuscitation) before specialized burn care, imaging, or transfer.
