Difficulty: HardTrauma and Burns

A 25-year-old man is brought to the trauma bay via ambulance after being ejected from a vehicle during a high-speed collision. On arrival, he is comatose with gurgling respirations. Vital signs are temperature 36.1°C (97.0°F), blood pressure 65/35 mm Hg, pulse 145/min, and respirations 8/min. Physical examination reveals a trachea deviated to the left, absent breath sounds on the right hemithorax, and dramatically distended neck veins. Anteroposterior compression of the pelvis reveals mechanical instability. Arrange the following critical interventions in the exact sequential order they should be performed according to Advanced Trauma Life Support (ATLS) priority protocols.

  1. 1Endotracheal intubation with inline cervical spine stabilization
  2. 2Right-sided needle decompression and tube thoracostomy
  3. 3Application of a commercial pelvic binder
  4. 4Focused Assessment with Sonography for Trauma (FAST) examination
  5. 5Transfer to the operating room for exploratory laparotomy

Answer

The correct sequence follows the ATLS ABCDE algorithm: Endotracheal intubation, followed by right-sided needle decompression and tube thoracostomy, then application of a pelvic binder, followed by a FAST examination, and finally transfer to the operating room for exploratory laparotomy.
The Advanced Trauma Life Support (ATLS) protocol mandates a strict ABCDE approach. Airway compromise (gurgling, coma) is the fastest mechanism of death and is treated first with intubation (A). Tension pneumothorax (tracheal deviation, distended neck veins) rapidly causes fatal obstructive shock and is treated next with thoracostomy (B). Massive hemorrhage from an unstable pelvis is stabilized next with a binder (C). Diagnostic adjuncts like the FAST scan are then used to identify internal bleeding sources, followed lastly by definitive operative care (laparotomy).

Step-by-Step Solution

1
Assess and secure the Airway (ATLS priority A).
Endotracheal intubation is performed.
The patient is comatose (GCS < 8) with gurgling respirations, indicating an unprotected and compromised airway requiring immediate intubation with cervical spine precautions.
2
Assess Breathing and ventilation (ATLS priority B).
Needle decompression and tube thoracostomy are performed on the right side.
The patient has a right-sided tension pneumothorax (tracheal deviation to the left, absent right breath sounds, distended neck veins, hypotension). This causes obstructive shock and hypoxia, which is universally fatal if not decompressed immediately after the airway is secured.
3
Assess Circulation and hemorrhage control (ATLS priority C).
A commercial pelvic binder is applied.
The patient is in profound hemorrhagic shock with a mechanically unstable pelvis. A pelvic binder mechanically reduces the pelvic volume, providing tamponade to bleeding venous plexuses and fractured bone ends.
4
Perform adjuncts to the primary survey.
A FAST examination is conducted.
With the airway secure, breathing restored, and the pelvis mechanically stabilized, a FAST exam rapidly identifies whether there is concurrent intra-abdominal hemorrhage contributing to the patient's severe shock.
5
Proceed to definitive care.
The patient is transferred to the operating room for exploratory laparotomy.
In a hemodynamically unstable trauma patient whose primary survey is complete, definitive surgical control of hemorrhage (often identified by the FAST scan) is the final mandatory step.

Key Concept

In complex polytrauma, the ATLS primary survey dictates a strict chronological algorithm (Airway, Breathing, Circulation, Disability, Exposure) to address the most rapidly fatal injuries first, regardless of the severity of subsequent injuries.
