Zorluk: ZorInitial Stabilization and Triage

A 45-year-old male construction worker is brought to the emergency department by emergency medical services after a concrete pillar collapsed on him. On arrival, paramedics are applying direct manual pressure to his right lower extremity, which has sustained a mid-thigh traumatic amputation with active, pulsatile arterial bleeding. The patient is unresponsive, opens his eyes only to painful stimuli, and is making gurgling sounds. There is an expanding hematoma on the right side of his neck. His respiratory rate is 8/min and shallow. His blood pressure is 70/40 mm Hg, and his pulse is 140/min and thready. Arrange the following management steps in the most appropriate chronological order.

  1. 1Apply a commercial tourniquet to the right proximal thigh
  2. 2Perform endotracheal intubation with inline cervical stabilization
  3. 3Establish bilateral large-bore peripheral intravenous access and initiate uncrossmatched blood transfusion
  4. 4Perform a focused assessment with sonography for trauma (FAST) examination
  5. 5Transport the patient for computed tomography imaging of the head and cervical spine

Cevap

The correct sequence prioritizes catastrophic hemorrhage control, followed by airway protection, circulatory resuscitation, bedside ultrasonography, and finally definitive imaging.
The correct chronological sequence exactly follows the Advanced Trauma Life Support (ATLS) <C>ABCDE framework. Catastrophic bleeding (the traumatic amputation) must be halted immediately with a tourniquet. Only then is the airway secured (intubation for GCS 6 and neck hematoma). Following the airway, severe hemorrhagic shock is treated with massive transfusion. Once stabilized, bedside diagnostics like the FAST exam are performed to identify internal bleeding, and only when stabilized is the patient moved for definitive CT imaging.

Adım Adım Çözüm

1
Identify and control catastrophic hemorrhage
Placement of a proximal tourniquet on the right thigh stops the pulsatile arterial bleeding.
Exsanguination from a major arterial injury will cause death within minutes, making it the absolute first priority in modern trauma resuscitation.
2
Assess and secure the airway with cervical spine protection
Endotracheal intubation is performed while maintaining inline stabilization of the neck.
The patient cannot protect his airway (GCS 6, gurgling) and has impending airway collapse from a neck hematoma. This must be addressed immediately after exsanguination is controlled.
3
Support circulation and manage shock
Bilateral large-bore IVs are placed and uncrossmatched blood products are administered.
The patient is in class IV hemorrhagic shock (BP 70/40, HR 140) requiring immediate volume replacement with blood products.
4
Evaluate for hidden sources of bleeding
A FAST examination is performed at the bedside.
Before leaving the resuscitation bay, the team must identify other immediate life threats such as intraperitoneal bleeding or cardiac tamponade.
5
Obtain definitive diagnostic imaging
The patient is transported to the CT scanner.
A patient can only be transported to the scanner once the airway is secure, hemorrhage is controlled, and hemodynamics are stabilized.

Anahtar Kavram

In the modern Advanced Trauma Life Support (ATLS) protocol, catastrophic external hemorrhage control (<C>) takes precedence over Airway (A), Breathing (B), and general Circulation (C) in the primary survey (<C>ABCDE approach).
