Difficulty: MediumInitial Stabilization and Triage

A 25-year-old male driver is transported to the trauma bay following a high-speed frontal motor vehicle collision. On arrival, he is unresponsive to verbal stimuli. His breathing is shallow with audible gurgling. Vital signs include a blood pressure of 72/40 mm Hg, pulse of 138/min, and respiratory rate of 8/min. Examination shows extensive maxillofacial ecchymosis and mechanical instability of the pelvic ring. Arrange the following interventions in the most appropriate chronological sequence for this patient's acute management.

  1. 1Secure the airway via endotracheal intubation
  2. 2Apply a pelvic binder and initiate uncrossmatched blood transfusion
  3. 3Perform a bedside focused assessment with sonography for trauma (FAST)
  4. 4Transport the patient for a computed tomography (CT) scan

Answer

The correct sequence of interventions is: 1) Secure the airway via endotracheal intubation, 2) Apply a pelvic binder and initiate uncrossmatched blood transfusion, 3) Perform a bedside focused assessment with sonography for trauma (FAST), and 4) Transport the patient for a computed tomography (CT) scan.
The Advanced Trauma Life Support (ATLS) protocol dictates a strict sequence of priorities: Airway, Breathing, Circulation, Disability, and Exposure. This patient has immediate airway compromise (gurgling, bradypnea, unresponsiveness) requiring intubation first. Next, profound hemorrhagic shock from suspected pelvic trauma necessitates hemorrhage control (pelvic binder) and volume resuscitation (blood products). Once these immediate, life-saving measures are initiated, a bedside FAST exam acts as an adjunct to identify occult bleeding. Finally, definitive imaging like a CT scan is reserved for patients who have been adequately stabilized, as the radiology suite is unsafe for an actively crashing patient.

Step-by-Step Solution

1
Assess and secure the airway.
The patient is successfully intubated.
The patient has gurgling respirations, a respiratory rate of 8/min, and is unresponsive, indicating an unprotected and inadequate airway. This is the 'A' in the primary survey.
2
Address circulation and active hemorrhage.
A pelvic binder is placed and massive transfusion is initiated.
The patient is in class IV hemorrhagic shock with an unstable pelvis. Early mechanical stabilization and blood products address the 'C' in the primary survey.
3
Utilize bedside diagnostic adjuncts.
A FAST exam is performed without leaving the resuscitation bay.
Once immediate airway and hemodynamic stabilization are underway, a FAST exam rapidly identifies intra-abdominal or pericardial hemorrhage to guide potential surgical intervention.
4
Obtain definitive diagnostic imaging.
The patient is transported to the CT scanner.
Only after the primary survey is complete, immediate life threats are managed, and the patient has achieved a degree of hemodynamic stability, is it safe to leave the resuscitation bay for advanced imaging.
