Difficulty: HardTrauma and Burns

A 2828-year-old male is brought to the trauma bay via helicopter emergency medical services following a severe industrial explosion. On arrival, he is unresponsive. Vital signs are temperature 35.2∘C35.2^{\circ}\text{C} (95.4∘F95.4^{\circ}\text{F}), blood pressure 70/40 mm Hg70/40\text{ mm Hg}, heart rate 148/min148/\text{min}, and respiratory rate 34/min34/\text{min}. Physical examination reveals sonorous respirations and massive maxillofacial trauma. The trachea is deviated to the left, and breath sounds are absent over the right hemithorax. There is a traumatic amputation of the right mid-thigh with continuous, high-volume pulsatile bleeding. His Glasgow Coma Scale score is 66. Based on current Advanced Trauma Life Support (ATLS) guidelines, arrange the following initial management steps in the correct chronological sequence.

  1. 1Apply a proximal right lower extremity tourniquet
  2. 2Perform endotracheal intubation with in-line cervical stabilization
  3. 3Perform a right-sided tube thoracostomy
  4. 4Initiate massive transfusion with uncrossmatched blood products
  5. 5Remove all clothing and apply external warming devices

Answer

The correct sequence is: 1) Apply a proximal right lower extremity tourniquet, 2) Perform endotracheal intubation with in-line cervical stabilization, 3) Perform a right-sided tube thoracostomy, 4) Initiate massive transfusion with uncrossmatched blood products, 5) Remove all clothing and apply external warming devices.
The Advanced Trauma Life Support (ATLS) primary survey protocol utilizes the <C>ABCDE algorithm to identify and treat the most immediate life-threatening injuries first. '<C>' stands for Catastrophic hemorrhage, which must be controlled instantly (e.g., via tourniquet for an amputation). Next is 'A' for Airway with cervical spine protection (intubation for GCS < 8). This is followed by 'B' for Breathing (tube thoracostomy for tension pneumothorax). Then 'C' for Circulation (massive transfusion for profound shock). The survey concludes with 'D' for Disability (neurologic exam) and 'E' for Exposure and environmental control (completely undressing the patient while preventing hypothermia).

Step-by-Step Solution

1
Address Catastrophic Hemorrhage (<C>)
Apply a proximal right lower extremity tourniquet.
Exsanguinating external hemorrhage will lead to death more rapidly than any other injury. Modern ATLS protocols prioritize catastrophic bleeding control before the airway.
2
Secure the Airway (A)
Perform endotracheal intubation with in-line cervical stabilization.
The patient is comatose (GCS 6) with sonorous respirations and maxillofacial trauma, indicating failure to protect the airway. A definitive airway must be established while restricting cervical spine motion.
3
Manage Breathing and Ventilation (B)
Perform a right-sided tube thoracostomy.
The patient has a right-sided tension pneumothorax (absent breath sounds, leftward tracheal deviation, hemodynamic instability) that must be decompressed immediately after the airway is secured.
4
Support Circulation (C)
Initiate massive transfusion with uncrossmatched blood products.
Following control of catastrophic bleeding and thoracic decompression, the patient's class IV hemorrhagic shock is resuscitated using balanced blood products rather than large volumes of crystalloid.
5
Perform Exposure/Environmental Control (E)
Remove all clothing and apply external warming devices.
The patient must be completely exposed to find all injuries, followed by immediate application of warm blankets to prevent the lethal triad of trauma (hypothermia, coagulopathy, acidosis).

Key Concept

The ATLS primary survey follows the <C>ABCDE sequence: Catastrophic hemorrhage control, Airway, Breathing, Circulation, Disability, and Exposure.
