Difficulty: MediumTrauma and Burns

A 40-year-old female is rescued from an enclosed house fire and brought to the emergency department. She has sustained deep partial-thickness and full-thickness burns over her trunk and extremities. Physical examination reveals soot in her oropharynx, singed nasal hairs, and hoarseness. Her right arm has a circumferential full-thickness burn, and the distal radial pulse is absent on Doppler ultrasound. Arrange the following clinical interventions in the most appropriate chronological sequence according to standard trauma and burn management protocols.

  1. 1Secure the airway via endotracheal intubation
  2. 2Establish large-bore intravenous access and start initial crystalloid infusion
  3. 3Remove clothing and estimate the total body surface area (TBSA) burned
  4. 4Adjust the fluid resuscitation rate using a weight-based formula
  5. 5Perform a bedside escharotomy on the right arm

Answer

The correct sequence is to first secure the airway via endotracheal intubation, followed by establishing IV access for initial fluids, estimating the TBSA burned, adjusting the fluid rate based on the TBSA, and finally performing an escharotomy on the right arm.
The management of severe trauma and burns follows a strict algorithm based on the primary survey to prevent immediate mortality. The first priority is always securing the Airway (A), especially given the signs of inhalation injury (soot, hoarseness), which predict rapid airway edema. Next, Circulation (C) must be supported by establishing intravenous access and initiating empiric fluids. After systemic stabilization, the patient is fully undressed during Exposure (E) to permit a comprehensive secondary survey, including the calculation of the Total Body Surface Area (TBSA) burned. Only after an accurate TBSA is obtained can the targeted fluid resuscitation rate be calculated and adjusted. Finally, localized limb-threatening complications, such as impaired perfusion from a circumferential burn, are addressed via escharotomy.

Step-by-Step Solution

1
Assess Airway (ATLS step A)
Identify inhalation injury and perform endotracheal intubation.
Soot, singed nasal hairs, and hoarseness indicate impending airway edema which can rapidly lead to fatal asphyxiation.
2
Assess Circulation (ATLS step C)
Establish large-bore IV access and begin empiric crystalloid infusion.
Systemic perfusion must be supported early in major burns before localized injuries are addressed.
3
Expose the patient (ATLS step E)
Remove clothing and calculate TBSA.
Full exposure is necessary to accurately assess the extent of the burn injury.
4
Formulate definitive fluid plan
Adjust IV fluid rate using a weight-based formula.
Accurate fluid resuscitation calculations depend on the measured TBSA from the exposure step.
5
Address limb-threatening injuries
Perform escharotomy on the right arm.
Circumferential burns causing absent distal pulses require surgical decompression to salvage the limb, but this is done only after systemic stabilization.

Key Concept

Management of severe burns follows ATLS principles: prioritizing airway protection, initiating systemic fluid resuscitation, calculating burn extent, adjusting fluid rates, and subsequently addressing localized limb-threatening complications.
