Closed head injuries (CHI) represent a significant portion of traumatic brain injuries (TBI) encountered in emergency settings. These injuries occur without an open wound or skull fracture that breaches the scalp or dura, often resulting from falls, motor vehicle accidents, or assaults. Prompt and effective initial management is crucial to reduce morbidity and mortality, preserve neurological function, and guide further treatment.

Initial Management of Closed Head Injury in Adults Initial Management of Closed Head Injury in Adults The first step in managing an adult with a suspected closed head injury is to ensure scene safety and initiate primary assessment following the principles of Advanced Trauma Life Support (ATLS). This begins with airway assessment—ensuring patency and protecting the airway if consciousness is compromised. Patients with decreased consciousness may require airway stabilization with techniques such as jaw-thrust maneuvers or, if needed, endotracheal intubation. Adequate oxygenation is vital; hypoxia (oxygen saturation below 90%) should be corrected promptly with supplemental oxygen, as hypoxia significantly worsens brain injury outcomes.
Next, breathing is assessed and managed. Ventilation should be optimized to maintain normal carbon dioxide levels (normocapnia), balancing the risk of hypoventilation-induced increased intracranial pressure (ICP) against hyperventilation-induced cerebral vasoconstriction. Circulatory status is checked via blood pressure and pulse, with prompt fluid resuscitation to maintain cerebral perfusion pressure (CPP). Hypotension (systolic BP < 90 mmHg) must be corrected immediately, as it is associated with worse neurological outcomes.

CS 9–12), or severe (GCS ≤ 8). A low GCS score warrants urgent neuroimaging and close neurological monitoring. Pupillary reflexes should be checked for size, reactivity, and asymmetry, as abnormalities may suggest increased ICP or herniation.
Exposure and environmental control are essential to identify other injuries and prevent hypothermia, which can exacerbate coagulopathy. The patient’s head should be kept elevated at approximately 30 degrees to facilitate venous drainage and reduce ICP. A cervical spine injury must be ruled out with immobilization until confirmed safe, given the mechanism of injury.
Neuroimaging, predominantly a non-contrast computed tomography (CT) scan of the head, is critical within the first hour for suspected moderate to severe injury. It can reveal intracranial hemorrhages, skull fractures, contusions, or edema. If intracranial pressure is suspected to be elevated or if neurological deterioration occurs, further measures such as intracranial monitoring and neurosurgical consultation are warranted.

Pharmacological interventions, like osmotic agents (mannitol or hypertonic saline), are reserved for cases with signs of elevated ICP and should be administered under specialist guidance.

Early intervention and stabilization can significantly influence outcomes and reduce the risk of long-term disability.
