Core Concept: Advanced Trauma Life Support (ATLS) protocol strictly prioritizes the ABCs (Airway, Breathing, Circulation). An unconscious patient (GCS < 8) cannot protect their airway and requires definitive airway management before addressing hemorrhage or circulation.
Clinical Presentation:
- Unconsciousness, massive external hemorrhage, pallor, and signs of severe hypovolemic shock.
Diagnosis:
- First-line: Rapid primary survey (ABCDE assessment).
- Gold standard: Clinical assessment of airway patency and level of consciousness.
Management:
- Acute: Immediate orotracheal intubation to secure the airway and prevent aspiration. Simultaneously or immediately after, apply a tourniquet or direct pressure to control massive extremity hemorrhage, followed by activating the massive transfusion protocol.
- Long-term/Definitive: Surgical exploration and repair of vascular injuries.
