A 19-year-old male is brought to the emergency department by ambulance after diving headfirst into a shallow swimming pool. On arrival, he is conscious but extremely anxious and speaking in one-word sentences. He reports an inability to move or feel his arms and legs. His respiratory effort is weak, with shallow, paradoxical abdominal breathing. Vital signs show a temperature of 36.5°C (97.7°F), blood pressure of 72/40 mmHg, heart rate of 52/min, and respiratory rate of 28/min with an oxygen saturation of 88% on room air. Arrange the following management steps in the most appropriate sequential order for the initial stabilization and triage of this patient.
- 1Perform a jaw-thrust maneuver while maintaining strict in-line cervical spine stabilization
- 2Definitively secure the airway via endotracheal intubation
- 3Administer a rapid bolus of intravenous isotonic crystalloid solution
- 4Initiate an intravenous infusion of a vasopressor such as norepinephrine
- 5Transport the patient for magnetic resonance imaging (MRI) of the cervical spine
Cevap
The correct sequence prioritizes the ATLS primary survey (Airway, Breathing, Circulation) before proceeding to diagnostic adjuncts. The order is: 1) jaw-thrust with c-spine stabilization, 2) endotracheal intubation, 3) crystalloid fluid bolus, 4) vasopressor infusion, and finally 5) MRI of the cervical spine.
The correct sequence adheres to the Advanced Trauma Life Support (ATLS) algorithm. Airway patency with cervical spine protection is paramount, necessitating an immediate jaw-thrust. Due to diaphragmatic weakness from high cervical injury (C3-C5), this is immediately followed by definitive endotracheal intubation. Next, Circulation is addressed; hypotension (neurogenic and potentially hypovolemic) requires an initial isotonic crystalloid bolus. Because neurogenic shock features loss of sympathetic vascular tone (resulting in bradycardia and hypotension), vasopressors (like norepinephrine) are subsequently initiated to maintain perfusion if fluids are insufficient. Finally, only after the patient is completely stabilized, diagnostic imaging such as an MRI can be safely obtained.

In trauma resuscitation, the ATLS sequence (Airway, Breathing, Circulation) must be strictly followed, prioritizing definitive airway management and initial fluid resuscitation before administering vasopressors or pursuing definitive diagnostic imaging.
