is any other concern about the child’s neurological state hospital assessment is appropriate.
A lumbar puncture may be necessary to exclude meningitis in the minority of cases,
particularly in children younger than 18 months. Ideally this decision should be made by an
experienced doctor. Investigations are not routinely indicated after febrile convulsions the
EEG is not helpful and brain scans are rarely indicated.
Subsequent medication
If febrile convulsions are prolonged it may be appropriate to teach parents to administer
buccal midazolam or rectal diazepam at home to prevent further prolonged episodes. There
is no convincing evidence that antipyretic measures reduce the frequency of febrile
recurrences or that the administration of intermittent or continuous prophylactic
anticonvulsant medication reduces the risk of later epilepsy. Prophylactic medication is now
not generally advised for children with febrile convulsions.
Information for carers
Many parents/carers are very distressed when they witness febrile convulsions in their
children and it should be a priority to inform them about the essentially benign nature of most
febrile convulsions. When assessing the prognosis it is relevant to consider the type of febrile
convulsion and the clinical context in which it occurs, but parents can be reassured that for
the majority of children with febrile convulsions the outcome is good and that medication is
rarely indicated. Ideally, written information should supplement the interview and there are
now excellent videos that provide advice and support for parents.
