Pediatric minor closed head injury.

Many studies have found conflicting evidence over the use of clinical indicators to predict intracranial injury in pediatric mild head injury. Although altered mental status, loss of consciousness, and abnormal neurologic examination have all been found to be more prevalent among head-injured children, studies have observed inconsistent results over their specificity and predictive value. Children older than 2 years have been evaluated, managed, and studied differently than those less than 2 years old. Evidence strongly supports a lower threshold to perform a CT scan in younger children because they have a higher risk of significant brain injury after blunt head trauma.
