Difficulty: HardInitial Stabilization and Triage

A 45-year-old man is brought to the emergency department after a high-speed motorcycle collision. Upon arrival, he is unresponsive with a Glasgow Coma Scale score of 7 (Eye: 1, Verbal: 2, Motor: 4). Vital signs are temperature 36.1°C (97.0°F), blood pressure 68/35 mmHg, pulse 138/min, and respirations 34/min with shallow effort. Pulse oximetry shows 84% on room air. Physical examination reveals a large scalp laceration, tracheal deviation to the left, and absent breath sounds over the right hemithorax. His pelvis crepitates upon gentle lateral compression, and his extremities are cool and mottled.

Arrange the following management steps in the most appropriate sequential order according to standard trauma resuscitation protocols.

  1. 1Perform rapid sequence endotracheal intubation with in-line cervical spine stabilization
  2. 2Perform a right-sided needle thoracostomy followed by a tube thoracostomy
  3. 3Apply a pelvic binder and initiate uncrossmatched packed red blood cell transfusion
  4. 4Perform a Focused Assessment with Sonography in Trauma (FAST) examination
  5. 5Transport the patient to the radiology suite for a computed tomography (CT) pan-scan

Answer

The correct sequence follows the Advanced Trauma Life Support (ATLS) ABCDE algorithm: 1) Endotracheal intubation, 2) Right-sided needle thoracostomy, 3) Pelvic binder and blood transfusion, 4) FAST examination, 5) CT pan-scan.
Trauma resuscitation requires strict adherence to the ABCDE paradigm to prevent premature death from the most rapidly fatal injuries. Airway (intubation) must be secured first due to the patient's low GCS and hypoxia. Breathing (chest decompression) immediately follows to treat the obstructive shock from the tension pneumothorax. Circulation (pelvic binder and blood) is then addressed to manage hemorrhagic shock. Only after these primary life threats are managed should diagnostic adjuncts (FAST exam) and secondary imaging (CT scan) be pursued.

Step-by-Step Solution

1
Assess and secure the Airway with cervical spine protection.
Endotracheal intubation is prioritized.
The patient has a GCS of 7 and severe hypoxia, indicating failure to protect the airway and impending respiratory collapse.
2
Assess Breathing and ventilation.
Needle thoracostomy followed by a chest tube is performed.
Absent right-sided breath sounds and leftward tracheal deviation indicate a tension pneumothorax, a rapidly fatal obstructive shock condition that must be decompressed immediately.
3
Assess Circulation and control hemorrhage.
A pelvic binder is applied and blood products are initiated.
Profound hypotension and a crepitant pelvis strongly suggest massive retroperitoneal hemorrhage from a pelvic fracture, requiring mechanical stabilization and fluid resuscitation.
4
Perform primary survey diagnostic adjuncts.
A FAST examination is conducted.
Once life-threatening ABC issues are addressed, ultrasound is used rapidly at the bedside to identify other sources of bleeding (e.g., intra-abdominal) without delaying resuscitation.
5
Proceed to the secondary survey and definitive imaging.
The patient is transported for a CT pan-scan.
Detailed radiographic imaging should only be obtained when the patient's airway is secure, tension physiology is reversed, and hemodynamics are stabilized enough to safely leave the resuscitation bay.

Key Concept

The ATLS sequence strictly dictates prioritizing Airway with cervical spine protection, followed by Breathing (relieving tension pneumothorax), then Circulation (hemorrhage control and resuscitation), before proceeding to diagnostic adjuncts (FAST) and definitive imaging (CT).
