Abstract
AbstractIntroductionApproximately half a million emergency department visits for traumatic brain injury (TBI) by children and adolescents occur each year. One of the complications of TBI is early-onset seizure. Current guidelines recommend the use of phenytoin for prevention of seizures following a TBI; however, several drug interactions and adverse reactions are associated with its use. Despite studies demonstrating efficacy of levetiracetam in adult patients, the efficacy and safety of levetiracetam in children with TBI is unknown. The purpose of this study was to determine the efficacy and safety of levetiracetam for the prevention of early-onset seizures in pediatric patients following TBI.MethodsA retrospective evaluation was conducted, which included children, ages 0 to 17 years, admitted secondary to a nonpenetrating TBI and who received levetiracetam for seizure prophylaxis for up to 7 days. The primary outcome was the number of children who had a seizure within the first 7 days following a TBI, and secondary outcomes included the number of adverse drug reactions.ResultsA total of 89 pediatrics patients with nonpenetrating TBI were identified and included in the study. Forty-seven patients received a mean dose of 10 mg/kg (SD ± 4.22) of levetiracetam twice a day, and 42 patients received 500 mg 2 times per day (based on adult dosing). Seizure activity was observed in only two patients (2.2%) within the first 7 days following TBI. A total of 13 patients (14.6%) experienced anemia, agitation, and elevation of liver enzymes during levetiracetam therapy.DiscussionThe study suggests that levetiracetam appears to be an effective and safe agent for early-onset seizure prophylaxis in pediatric patients with TBI as indicated by the low number of patients with seizures. The reported adverse reactions may have resulted from the trauma rather than the use of levetiracetam.
