Status epilepticus and acute serial seizures in children.

Status epilepticus is defined as a seizure that persists for a sufficient length of time or is repeated frequently enough to produce a fixed and enduring epileptic condition of 30 minutes or longer. Status epilepticus is a life-threatening condition that often occurs in children. The degree of mortality and neurologic morbidity, as well as the risk for recurrence, is highly dependent on the etiology and duration of the seizures. Although much has been written about pediatric status epilepticus, many issues remain unresolved. A better understanding of the different types of seizures and their etiologies may help in the prevention and treatment of status epilepticus. The vast extent of status epilepticus in both children and adults mandates that new options for prevention and treatment be given a close scrutiny and high priority. This article will review the most current information on convulsive and nonconvulsive status epilepticus, including the potential for neurologic damage, changes in magnetic resonance imaging after status epilepticus, risk for recurrence, and current treatment options available for treating status epilepticus in children.
