Difficulty: MediumInitial Stabilization and Triage

A 29-year-old man is brought to the trauma resuscitation bay following a high-speed motor vehicle collision. Emergency medical services report a prolonged extrication time. Upon arrival, the patient is unresponsive. Vital signs show a pulse of 135/min, blood pressure of 82/50 mm Hg, and a respiratory rate of 35/min. Pulse oximetry indicates an oxygen saturation of 85% despite high-flow supplemental oxygen. Physical examination reveals significant maxillofacial trauma with active bleeding pooling in the oropharynx. The right hemithorax is hyperresonant to percussion with absent breath sounds. The abdomen is distended and rigid. Arrange the following management steps in the most appropriate sequential order according to standardized trauma resuscitation protocols.

  1. 1Perform endotracheal intubation with manual in-line stabilization
  2. 2Perform a right-sided tube thoracostomy
  3. 3Establish large-bore intravenous access and initiate massive transfusion
  4. 4Perform a Focused Assessment with Sonography for Trauma (FAST)
  5. 5Transfer the patient to the operating room for exploratory laparotomy

Answer

The correct sequence is to first secure the airway via intubation, then manage breathing with a right-sided tube thoracostomy, next support circulation by establishing IV access and initiating massive transfusion, subsequently perform a FAST exam, and finally transfer the patient to the operating room.
The correct sequence adheres strictly to the primary survey protocol (ABCDE) for trauma resuscitation. Airway compromise from unresponsiveness and oropharyngeal bleeding is the most immediate threat to life and must be addressed first. Tension pneumothorax (Breathing) is the next immediate cause of death and is treated second. Hemorrhagic shock (Circulation) is addressed third through IV access and blood products. Only after these immediate threats are stabilized should diagnostic adjuncts like FAST be performed, followed by definitive disposition to the operating room.

Step-by-Step Solution

1
Assess and secure the airway (A).
Endotracheal intubation is performed.
The patient is unresponsive (GCS < 8 implies inability to protect airway) and has active bleeding in the oropharynx from maxillofacial trauma. Securing a definitive airway with cervical spine protection is the absolute first step.
2
Assess and manage breathing and ventilation (B).
A right-sided tube thoracostomy is placed.
The patient has absent right-sided breath sounds and hyperresonance in the setting of severe hypoxia and shock, highly suspicious for a tension pneumothorax. This must be decompressed immediately after the airway is secured.
3
Assess and manage circulation (C).
Large-bore IV access is obtained and a massive transfusion protocol is initiated.
The patient is in Class III or IV hemorrhagic shock, indicated by hypotension (82/50 mm Hg) and marked tachycardia (135/min). Fluid and blood resuscitation must begin to restore end-organ perfusion.
4
Perform diagnostic adjuncts to the primary survey.
A FAST exam is conducted.
With ABCs addressed, bedside imaging is rapidly utilized to confirm the presumed source of hemorrhagic shock (in this case, intra-abdominal bleeding evident by the rigid abdomen).
5
Determine patient disposition for definitive care.
The patient is transferred to the operating room.
Following initial stabilization and identification of intra-abdominal hemorrhage, the patient requires emergent exploratory laparotomy to control the bleeding.

Key Concept

In polytrauma patients, initial stabilization strictly follows the Advanced Trauma Life Support (ATLS) ABCDE algorithm: Airway, Breathing, Circulation, Disability, and Exposure, prior to diagnostic imaging or definitive surgical care.
