Paramedics arrive at the trauma bay with a 19-year-old male who was injured in a high-speed skateboarding accident without a helmet. He is profoundly comatose with a Glasgow Coma Scale score of 5. Initial physical examination reveals a fixed, dilated left pupil and right-sided extensor posturing in response to pain. Determine the correct chronological order for the subsequent management steps in this scenario.
- 1Perform endotracheal intubation
- 2Administer intravenous hypertonic saline
- 3Obtain a non-contrast head computed tomography (CT) scan
- 4Proceed with an emergent decompressive craniotomy
Answer
The correct sequence of emergency management is: 1) Perform endotracheal intubation, 2) Administer intravenous hypertonic saline, 3) Obtain a non-contrast head CT scan, 4) Proceed with an emergent decompressive craniotomy.
In the setting of severe head trauma and suspected elevated intracranial pressure, the Advanced Trauma Life Support (ATLS) algorithm mandates securing the airway first (intubation for GCS less than or equal to 8). Once the airway and hemodynamics are stabilized, empirical medical treatment for impending herniation (using osmotic agents like hypertonic saline or mannitol) must be initiated to temporize the patient. The patient is then quickly transported for a non-contrast head CT scan to determine the precise anatomical lesion. Finally, based on the specific CT findings, a neurosurgeon performs definitive operative decompression, such as a craniotomy.
Step-by-Step Solution
Key Concept
The management of severe traumatic brain injury with signs of imminent herniation prioritizes airway protection first, followed by empiric medical reduction of intracranial pressure, diagnostic imaging, and finally definitive surgical decompression.
