Emergency medical services arrive at the trauma center with a 32-year-old male victim of a high-speed motorcycle crash. He was found unresponsive at the scene after a prolonged extrication time. Upon presentation, the patient exhibits loud, gurgling respirations and central cyanosis. Hemodynamic monitoring reveals a blood pressure of 65/40 mmHg and a heart rate of 145/min. The physical examination is notable for active, pulsatile arterial bleeding from a severely mangled left lower extremity. Arrange the following acute management steps in the correct chronological sequence according to the Advanced Trauma Life Support (ATLS) protocol.
- 1Apply a tourniquet proximal to the left lower extremity injury
- 2Perform endotracheal intubation with manual in-line cervical spine stabilization
- 3Assess bilateral breath sounds and chest wall excursion
- 4Establish large-bore intravenous access and initiate uncrossmatched blood transfusion
- 5Completely undress the patient to systematically evaluate for other occult injuries
Cevap
The correct sequence follows the <C>ABCDE approach: control catastrophic hemorrhage first, followed by airway, breathing, circulation, and exposure.
The Advanced Trauma Life Support (ATLS) 10th edition update emphasizes the <C>ABCDE approach. <C> stands for Catastrophic hemorrhage control, which must occur before A (Airway), B (Breathing), C (Circulation), D (Disability), and E (Exposure). In this patient with pulsatile arterial bleeding, a tourniquet must be applied first. This is followed by securing the airway with c-spine precautions due to unresponsiveness and gurgling. Next, breathing is assessed. Then, circulation is supported with blood products for severe shock. Finally, the patient is fully exposed to find hidden injuries.

Anahtar Kavram
The ATLS <C>ABCDE algorithm prioritizes catastrophic hemorrhage control before traditional airway management.
