Do children require hospitalization after immediate posttraumatic seizures?
OBJECTIVE
We determine whether children with immediate posttraumatic seizures require hospitalization for observation of possible neurologic complications.


METHODS
This was a prospective observational cohort study of children younger than 18 years with blunt head trauma resulting in immediate posttraumatic seizures. Patients were examined by faculty emergency physicians and underwent cranial computed tomography (CT) scanning. Children were divided into 2 cohorts according to the presence or absence of traumatic brain injury on cranial CT scan, with the a priori assumption that children with posttraumatic seizures who have abnormal cranial CT scan results require hospitalization. The outcomes of interest were neurologic complications (including further seizure activity or neurologic deficits) or the necessity for neurosurgical intervention. Medical records of hospitalized patients were reviewed, and patients discharged from the emergency department (ED) were contacted by telephone approximately 1 week after hospital discharge to identify those who developed short-term neurologic complications.


RESULTS
Sixty-three children with a median age of 7 years (interquartile range 3 to 14 years) had posttraumatic seizures, and all but 1 child underwent cranial CT imaging. Ten (16%; 95% confidence interval [CI] 8% to 27%) patients had traumatic brain injuries on CT scan, and all were hospitalized. Three of these 10 patients underwent craniotomy, and 2 patients had further seizure activity. Fifty-two patients had normal cranial CT scan results, and 20 patients were hospitalized for observation. Telephone follow-up was obtained in 31 of the 32 patients with normal CT scan results who were discharged from the ED. None of the 52 patients (0%; 95% CI 0% to 5.6%) with normal cranial CT scan results had further seizure activity or required neurosurgical interventions.


CONCLUSIONS
Children with normal neurologic examination results and normal cranial CT scan results after immediate posttraumatic seizures are at low risk for further short-term complications that require immediate hospitalization. These children may be considered for discharge home from the ED.
