All patients with suspected traumatic brain injury should be assessed and stabilised using an Airway, Breathing, Circulation (ABC) approach.
An urgent (within 1 hour) computed tomographic (CT) head scan should be performed in those identified as having a risk factor for brain injury (i.e., intracranial complication). All patients on anticoagulant treatment and with no indications for urgent CT scan need to be scanned within 8 hours of the head injury.
Diagnosis of mild traumatic brain injury is clinical. Selected patients may be admitted to hospital for observation.
Patients with no indications for CT scan or with a normal CT scan may be discharged from the accident and emergency department if there is somebody suitable at home to supervise them.
The need for analgesia and antiemetics should be considered in all patients.
A mild traumatic brain injury is a head injury due to a direct blow to the head or deceleration of the head from an impulsive force that results in a change in mental status.
This topic covers the acute management of mild traumatic brain injury in adults and children.
