Zorluk: ZorInitial Stabilization and Triage

A 28-year-old male is brought to the emergency department by paramedics following a high-speed motorcycle collision. He was found approximately 30 feet from his vehicle. On arrival, he is unresponsive to verbal stimuli and only groans to deep pain, yielding a Glasgow Coma Scale score of 7. His blood pressure is 68/40 mmHg, heart rate is 142/min, and respiratory rate is 8/min with shallow effort. Physical examination reveals a partially amputated right lower extremity at the level of the distal femur. The field dressings applied by emergency medical services are completely soaked through, and there is active, pulsatile bleeding from the wound. Breath sounds are clear and equal bilaterally. Arrange the following initial management steps in the most appropriate sequential order.

  1. 1Apply a commercial tourniquet proximal to the right lower extremity amputation site
  2. 2Secure the airway via rapid sequence endotracheal intubation
  3. 3Initiate a massive transfusion protocol with uncrossmatched blood products
  4. 4Perform a focused assessment with sonography for trauma (FAST) examination
  5. 5Transport the patient for computed tomography (CT) imaging of the head and spine

Cevap

The correct sequence is to first apply a proximal tourniquet for catastrophic hemorrhage control, followed by endotracheal intubation for airway protection, initiation of a massive transfusion protocol, bedside FAST examination, and finally transport for CT imaging once hemodynamically stabilized.
Modern trauma resuscitation protocols prioritize the control of catastrophic, exsanguinating external hemorrhage (<C> or X) as the absolute first step, superseding traditional airway management. If induction agents and positive pressure ventilation are administered before controlling massive bleeding and restoring volume, the resulting loss of sympathetic tone and decreased venous return will likely precipitate cardiovascular collapse. Therefore, a tourniquet must be applied immediately. Following hemorrhage control, the standard ABC sequence resumes: the patient requires endotracheal intubation for a GCS < 8 and poor respiratory effort (Airway/Breathing). Next, class IV hemorrhagic shock is treated with balanced blood product resuscitation (Circulation). Bedside adjuncts like the FAST exam follow to evaluate for concurrent internal bleeding. Finally, transport for CT imaging is only appropriate once the patient is hemodynamically stabilized and the primary survey is complete.

Adım Adım Çözüm

1
Identify and control catastrophic external hemorrhage.
Application of a proximal tourniquet to the right lower extremity.
Exsanguination is the most immediate threat to life and takes precedence over traditional airway management in modern trauma protocols.
2
Assess airway and breathing.
Perform rapid sequence endotracheal intubation.
A Glasgow Coma Scale score of 7 and respiratory rate of 8/min require definitive airway protection and ventilatory support.
3
Assess circulation and treat shock.
Initiate massive transfusion protocol.
The patient is in class IV hemorrhagic shock, which requires immediate resuscitation with blood products rather than crystalloids.
4
Perform primary survey adjuncts.
Conduct a FAST examination.
To quickly identify potential internal, non-compressible sources of hemorrhage within the abdomen or pericardium.
5
Proceed to the secondary survey and definitive diagnostics.
Transport for CT imaging of the head and spine.
Definitive imaging of the head and cervical spine is necessary but only safe once the patient is successfully resuscitated and hemodynamically stable.

In modern trauma resuscitation, control of catastrophic external hemorrhage (<C>) supersedes traditional airway management (ABC), forming the <C>ABCDE protocol.
