Immediate CT Scan for Head Injury

Rationale for Immediate Imaging

The American College of Radiology recommends that a CT scan of the brain be performed immediately for any child who experiences seizures after a head injury, as post-traumatic seizures may indicate the presence of intracranial hemorrhage or brain injury requiring urgent intervention 1, 2
Post-traumatic seizures occur in 2.4% of mild head injuries and 28-83% of severe head injuries, making them an important warning sign 1, 2
CT scans detect 100% of lesions requiring urgent treatment in mild head injury cases, and studies have shown that 7% of patients have lesions requiring immediate surgical intervention 1
CT imaging is suitable for acute cases to quickly identify acute intracranial hemorrhage or mass effect 1, 2

A complete neurological examination should be performed immediately to look for specific warning signs, including post-ictal focal deficits 3
Assessment of the level of consciousness and its return to normal 4
Examination for signs of severe head injury 1

Emergency medical services should be activated immediately if the child meets multiple criteria, including first-time seizure 4
Seizure with traumatic injury 4
Seizure lasting more than 5 minutes 4
Failure to return to normal within 5-10 minutes after the seizure stops 4

Immediate safety measures during a seizure include placing the child on the ground to prevent falls 5
Placing the child in the recovery position to reduce the risk of aspiration 5
Removing any objects around the child that may cause injury 5
Not restraining the child or putting anything in their mouth 4, 5
Not giving any food, fluids, or medications by mouth 4, 5

Failing to perform a CT scan of the brain because the seizure was short or the child regained consciousness - this is an error because head injury with seizures requires exclusion of hemorrhage 1, 2
