Difficulty: EasyInitial Stabilization and Triage

Emergency medical services arrive at the trauma bay with a 35-year-old construction worker who fell approximately 20 feet from scaffolding. On presentation, the patient is obtunded with gurgling respirations and profound maxillofacial bleeding. The cardiac monitor displays a sinus tachycardia of 138/min. Noninvasive blood pressure is 75/40 mm Hg, and respiratory rate is 28/min.

According to standard trauma resuscitation protocols, arrange the following initial stabilization steps in the most appropriate chronological sequence.

  1. 1Secure the airway via endotracheal intubation while maintaining strict cervical spine immobilization
  2. 2Auscultate the lung fields bilaterally and assess for signs of a tension pneumothorax
  3. 3Establish bilateral large-bore intravenous access and initiate rapid fluid resuscitation
  4. 4Evaluate the patient's neurologic status using the Glasgow Coma Scale and check pupillary reflexes
  5. 5Completely undress the patient to examine for occult injuries while applying warm blankets to prevent hypothermia

Answer

The correct sequence follows the ATLS primary survey algorithm: 1) Secure the airway, 2) Assess breathing, 3) Establish circulation, 4) Evaluate disability, and 5) Expose the patient.
In the initial management of severe trauma, resuscitation must follow a strict algorithmic approach (the primary survey) to identify and treat the most immediately life-threatening injuries first. Securing the airway with simultaneous cervical spine protection is the absolute first step, as airway loss kills fastest. This is followed by assessing breathing and ventilation to ensure oxygenation. Only once the airway and breathing are established should circulation be addressed with intravenous access and fluid resuscitation. Disability is assessed next to establish baseline neurologic function, followed finally by exposing the patient completely to check for occult injuries while actively preventing hypothermia.

Step-by-Step Solution

1
Identify the most immediate threat to life.
The patient has an unprotected airway with gurgling respirations and facial bleeding.
Airway compromise leads to death more rapidly than breathing or circulatory failure, making it the first priority (Airway).
2
Determine the next requirement for cellular survival.
Once the airway is patent, adequate gas exchange must be ensured.
Without effective ventilation, a patent airway is useless. The lungs must be assessed for injuries like tension pneumothorax (Breathing).
3
Address the patient's profound hemodynamic instability.
The patient is in hypovolemic shock (blood pressure 75/40 mm Hg, heart rate 138/min).
After securing oxygenation, restoring intravascular volume and controlling hemorrhage is critical (Circulation).
4
Complete the final phases of the primary survey.
The neurologic status is assessed, followed by a full body exposure.
A baseline neurologic exam (Disability) is needed before sedation, and exposing the patient (Exposure) ensures no hidden life threats are missed.

Key Concept

The initial stabilization of a trauma patient strictly follows the primary survey algorithm: Airway (with cervical spine protection), Breathing, Circulation, Disability, and Exposure.
