A 22-year-old male is brought to the emergency department after diving headfirst into a shallow lake. He is conscious but in severe respiratory distress, using accessory muscles to breathe. He reports an inability to feel or move his arms or legs. Vital signs include a temperature of 36.5°C (97.7°F), heart rate of 52/min, blood pressure of 80/40 mmHg, respiratory rate of 34/min with shallow effort, and oxygen saturation of 85% on room air. Physical examination demonstrates prominent diaphragmatic breathing, flaccid paralysis of all four extremities, and absent deep tendon reflexes.
Arrange the following steps in the most appropriate sequential order for the initial stabilization and diagnostic workup of this patient.
- 1Perform endotracheal intubation with manual in-line cervical spine stabilization
- 2Administer an intravenous crystalloid fluid bolus and prepare vasopressors
- 3Obtain a portable chest radiograph
- 4Transport the patient for a computed tomography scan of the cervical spine
Cevap
The correct sequence prioritizes the primary trauma survey (Airway, Breathing, Circulation) followed by resuscitation adjuncts and finally definitive diagnostic imaging.
The initial stabilization of any trauma patient strictly follows the standard primary survey protocol. In a patient with a high cervical spine injury causing respiratory failure (hypoxemia, tachypnea, diaphragmatic breathing) and neurogenic shock (hypotension, bradycardia, flaccid paralysis), the absolute first priority is securing the airway while maintaining in-line cervical stabilization. Once the airway is protected and oxygenation is established, the next immediate step is to support circulation with intravenous fluids and vasopressors to maintain adequate spinal cord perfusion. Only after the airway and circulation are stabilized should resuscitation adjuncts, such as a portable chest radiograph to confirm tube placement, be performed. Definitive imaging, such as a CT scan of the cervical spine, is the final step in this sequence, as the patient must be stable enough to safely leave the resuscitation bay.

Anahtar Kavram
In trauma and suspected spinal cord injury, initial management strictly follows the primary survey, ensuring the airway is secured with cervical spine precautions before addressing circulation or pursuing definitive diagnostic imaging.
