Zorluk: Çok zorTrauma and Burns

A 28-year-old military contractor is brought to the trauma bay immediately after an improvised explosive device (IED) blast. On arrival, bright red blood is vigorously spurting from a right mid-thigh amputation. The patient has agonal respirations, severe maxillofacial crush injuries, and a hoarse, gurgling voice. Physical examination reveals absent breath sounds on the left hemithorax with distended neck veins. His blood pressure is undetectable, and his heart rate is 145/min. Arrange the following critical management steps in the correct chronological order according to the Advanced Trauma Life Support (ATLS) primary survey protocol.

  1. 1Application of a proximal arterial tourniquet to the right lower extremity
  2. 2Establishment of a definitive airway with in-line cervical spine restriction
  3. 3Decompression of the left pleural space via thoracostomy
  4. 4Initiation of massive transfusion protocol via large-bore intravenous access
  5. 5Assessment of pupillary response and motor function

Cevap

The correct sequence is: Application of a proximal arterial tourniquet, followed by Establishment of a definitive airway, then Decompression of the left pleural space, followed by Initiation of massive transfusion protocol, and finally Assessment of pupillary response and motor function.
The Advanced Trauma Life Support (ATLS) 10th edition protocol utilizes the <C>ABCDE algorithm, emphasizing that Catastrophic external hemorrhage (<C>) must be addressed prior to Airway (A). If a patient has massive, life-threatening external bleeding (such as a spurting amputation), attempting any other intervention before applying a tourniquet or direct pressure will result in exsanguination. Following catastrophic hemorrhage control, the standard sequence resumes: Airway maintenance with cervical spine restriction (managing the maxillofacial trauma), Breathing and ventilation (addressing the tension pneumothorax), Circulation (intravenous access and massive transfusion for shock), and Disability (neurologic evaluation).

Adım Adım Çözüm

1
Identify the most immediate threat to life based on the <C>ABCDE protocol.
The vigorously spurting right mid-thigh amputation represents catastrophic external hemorrhage.
Massive arterial bleeding will cause fatal exsanguination within seconds to minutes, preceding death from airway loss. This must be addressed first with a tourniquet.
2
Assess and secure the airway while maintaining cervical spine restriction.
The maxillofacial crush injury and agonal respirations necessitate a definitive airway (e.g., surgical cricothyroidotomy or endotracheal intubation).
Once exsanguination is halted, hypoxia from an unprotected or obstructed airway is the next most rapid cause of death.
3
Evaluate breathing and manage impaired ventilation.
Absent left breath sounds and distended neck veins are diagnostic of a tension pneumothorax, requiring immediate thoracostomy.
A tension pneumothorax severely impairs both ventilation and venous return, and must be decompressed immediately after the airway is secured.
4
Assess systemic circulation and initiate volume resuscitation.
The undetectable blood pressure and severe tachycardia require the initiation of a massive transfusion protocol via large-bore access.
Restoring intravascular volume is critical for tissue perfusion, but must follow hemorrhage control, airway, and breathing to ensure oxygenated blood is being circulated.
5
Perform a baseline neurologic assessment.
Pupillary response and motor function (Disability) are evaluated.
Establishing a baseline neurologic exam dictates further neurosurgical intervention, but can only be accurately assessed once hypoxia and hypotension are addressed.
