Difficulty: Very hardInitial Stabilization and Triage

Emergency Medical Services arrives at the trauma bay with a 28-year-old construction worker who fell approximately 30 feet from scaffolding. Upon transfer to the resuscitation stretcher, the patient demonstrates decerebrate posturing, absent vocalizations, and no eye opening to sternal rub.

Initial assessment reveals the following vital parameters:
- Temperature: 36.2°C (97.2°F)
- Heart rate: 138/min
- Blood pressure: 78/42 mm Hg
- Respiratory rate: 8/min (shallow and irregular)
- Oxygen saturation: 88% on ambient air

A rapid physical survey identifies a large, actively bleeding avulsion of the right parietal scalp. Neurologic evaluation shows anisocoria, with the right pupil fixed and dilated at 7 mm while the left is 3 mm and reactive. The left thigh exhibits massive swelling and a noticeable angular deformity.

Arrange the following management steps in the most appropriate chronological sequence of execution to stabilize this critically ill patient.

  1. 1Perform endotracheal intubation with in-line cervical spine stabilization
  2. 2Initiate a massive transfusion protocol with uncrossmatched group O blood products
  3. 3Administer intravenous hypertonic saline
  4. 4Transport the patient to the radiology suite for a non-contrast CT scan of the head

Answer

The correct sequence of steps follows the ATLS protocol: secure the airway first, restore circulation to maintain cerebral perfusion, administer osmotic therapy for impending herniation using an agent that does not worsen hypovolemia, and finally obtain diagnostic imaging only after stabilization.
The management of severe polytrauma with traumatic brain injury requires strict adherence to the ABCDE priorities. Airway control (intubation) prevents the massive secondary brain insult of hypoxia. Circulation management (blood transfusion) restores the mean arterial pressure, which is essential because cerebral perfusion pressure relies entirely on systemic pressure. Only after these systemic parameters are secured should targeted Disability interventions (hypertonic saline for herniation) be prioritized. Finally, diagnostic imaging is an adjunct that must be delayed until the patient is physiologically stable enough to leave the trauma bay.

Step-by-Step Solution

1
Evaluate and secure the airway.
Endotracheal intubation with in-line cervical spine stabilization is performed.
The patient has a Glasgow Coma Scale (GCS) score of 4 and hypoventilation (RR 8/min, SpO2 88%), indicating an inability to protect the airway and a critical need for oxygenation to prevent secondary anoxic brain injury.
2
Restore circulating volume and perfusion pressure.
A massive transfusion protocol is initiated with uncrossmatched blood products.
The patient is in severe hemorrhagic shock (BP 78/42, HR 138) likely due to the femur fracture and scalp avulsion. Restoring mean arterial pressure (MAP) is physiologically required to maintain cerebral perfusion pressure (CPP = MAP - ICP).
3
Address the acute intracranial hypertension.
Intravenous hypertonic saline is administered.
The fixed and dilated right pupil indicates impending uncal herniation. Hypertonic saline reduces intracranial pressure osmotically without inducing the massive diuresis and volume depletion that mannitol would cause.
4
Obtain definitive diagnostic imaging.
The patient is transported for a non-contrast CT scan of the head.
It is only safe to transport a critically ill trauma patient out of the resuscitation bay for imaging after the ABCs are stabilized and the brain is protected from hypoxia and hypotension.

Key Concept

In polytrauma with concurrent hemorrhagic shock and traumatic brain injury, the primary survey dictates securing the airway and restoring circulating volume (to maintain cerebral perfusion pressure) before initiating specific osmotic therapies or obtaining diagnostic imaging.
