Which prehospital action is most essential to prevent secondary brain injury in suspected TBI?

• A. Secure airway with cervical spine protection and protect the spine
• B. Apply heat to the forehead to prevent fever
• C. Place the patient in a prone position during transport
• D. Administer diuretics to lower intracranial pressure prehospital

Answer: (A)

Preventing secondary brain injury hinges on protecting the brain from hypoxia and inadequate perfusion while preventing any further injury to the spine. The most essential prehospital action is securing the airway with cervical spine protection and immobilizing the spine. When the airway is compromised, the brain quickly suffers from low oxygen levels, which accelerates secondary damage after the initial injury. Keeping the airway open with gentle maneuvers (like a jaw-thrust) and delivering adequate oxygen helps ensure the brain tissues continue to receive enough oxygen during transport. Simultaneously, keeping the spine immobilized prevents movement that could worsen cervical or spinal injuries, preserve neurologic function, and avoid added trauma that could worsen overall outcomes.

Other choices don’t address these critical immediate needs. Temperature management with forehead heat isn’t the urgent, field-level priority for preventing secondary injury. Placing the patient in a prone position can obstruct airway access and complicate spine protection. Administering diuretics to lower intracranial pressure isn’t appropriate prehospital care due to safety concerns and lack of monitoring in the field.
