We aim to assess the effect of anti-epileptic drug (AED) prophylaxis for early or late posttraumatic seizures, targeting the pediatric population with traumatic brain injury (TBI). We systematically searched for studies reporting the incidence of posttraumatic seizures in pediatric patients who suffered from TBI and received AEDs prophylactically following their TBI incident. Studies that included adult patients, adult and pediatric patients but did not report results for the pediatric population separately, and patients who did not suffer from a TBI were excluded. Studies that did not indicate the use of antiepileptic drugs prophylactically following TBI were excluded. A total of 10 studies were included involving 4621 posttraumatic brain injury patients of the pediatric age population (<18). Five studies assessed the effect of prophylaxis on early seizures, four on late seizures and one on any seizure. The mean incidence of posttraumatic seizures with AED prophylaxis was 8% for early seizures and 7.1% for late seizures. Moreover, one study revealed no benefit of AED prophylaxis for early posttraumatic seizures. Meta-analysis revealed a significant difference in the incidence of early posttraumatic seizures with antiepileptic prophylaxis. However, no significant difference for late posttraumatic seizures has been shown. In conclusion, AED prophylaxis seems to be effective against early posttraumatic seizures for the pediatric population, with levetiracetam possibly being more effective. Also, there is no observed benefit for late posttraumatic seizures.
