Evaluation and treatment of the child with febrile seizure.

Up to 5 percent of children in North America and western Europe experience at least one episode of febrile seizure before six years of age. Most of these seizures are self-limited and patients do not require treatment. Continuous therapy after the seizure is not effective in reducing the development of afebrile seizures. Antipyretics are effective in reducing the risk of febrile seizures if given early in the illness. Immediate care for the patient who has had a febrile seizure includes stopping the seizure, if prolonged, and evaluating the patient for the cause of the fever. Bacterial infections are treatable sources of fever but are not usually the cause of the fever that triggers a seizure. The patient must be assessed for these treatable sources. Long-term consequences of febrile seizure are rare in children who are otherwise healthy. Current recommendations do not support the use of continuing or intermittent neuroleptic or benzodiazepine suppressive therapies after a simple febrile seizure.
