Difficulty: EasyTrauma and Burns

Emergency medical services bring a 22-year-old male to the trauma bay following an ejection from a moving vehicle. The patient is semi-conscious, with visible facial trauma and a deformed right lower extremity with surrounding ecchymosis. Arrange the following initial management steps in the correct chronological sequence according to the Advanced Trauma Life Support (ATLS) primary survey protocol.

  1. 1Evaluate airway patency and clear any oral debris while maintaining strict cervical spine restriction.
  2. 2Assess symmetric chest wall expansion, auscultate breath sounds, and apply supplemental oxygen.
  3. 3Establish large-bore intravenous access, evaluate peripheral pulses, and assess tissue perfusion.
  4. 4Perform a rapid neurologic evaluation by assessing pupillary response and calculating the Glasgow Coma Scale score.
  5. 5Completely undress the patient to identify all potential injuries while using warm blankets to prevent hypothermia.

Answer

The correct sequence follows the ATLS primary survey ABCDE protocol: Airway, Breathing, Circulation, Disability, and Exposure.
The Advanced Trauma Life Support (ATLS) protocol mandates a sequential approach to trauma resuscitation known as the primary survey (ABCDE). Airway with cervical spine protection is always first, as airway obstruction causes the fastest mortality. Breathing follows to ensure gas exchange. Circulation is third to address shock and perfusion. Disability provides a baseline neurologic assessment. Finally, Exposure ensures all injuries are identified while preventing hypothermia. Skipping or rearranging these steps can lead to missed life-threatening conditions.

Step-by-Step Solution

1
Identify the clinical scenario
The patient is a trauma victim requiring initial evaluation and resuscitation.
Trauma resuscitations follow a standardized algorithm to prioritize the most life-threatening conditions first.
2
Determine the first priority (A)
Airway patency with cervical spine restriction must be evaluated first.
Loss of airway kills more rapidly than any other injury mechanism.
3
Determine the second priority (B)
Breathing and ventilation assessment follows airway management.
A patent airway is useless if the patient cannot adequately exchange gases.
4
Determine the third priority (C)
Circulation and hemorrhage control are assessed next.
Once oxygen is reaching the lungs, the cardiovascular system must be able to deliver it to tissues.
5
Determine the fourth priority (D)
Disability (neurologic evaluation) is performed.
A rapid assessment of neurologic status helps identify severe traumatic brain injury requiring urgent intervention.
6
Determine the final priority (E)
Exposure and environmental control conclude the primary survey.
Full exposure is necessary to find hidden injuries, followed by immediate warming to prevent trauma-induced hypothermia.

Key Concept

The Advanced Trauma Life Support (ATLS) primary survey follows a strict ABCDE algorithm to address the most immediately life-threatening injuries first.
