Definition/ Clinical Manifestations

greater Generalized tonic-clonic seizures Less than 15 minutes Does not recur within the same

abnormality

Incidence
2% - 5% have febrile seizures by 5 years old (US)
5% -10% for India, 8.8% for Japan, 14% for Guam,0.35% for Hong Kong, and 0.5-1.5% for China.

Diagnostics
Lumbar puncture should be performed in all children below 18 months for benign febrile convulsions For >/= 18months, it is recommended in
the presence of clinical signs of meningitis
Neuroimaging studies should not be routinely performed in children for benign febrile seizuresCPG on First Simple Febrile
Seizure
![Page 49: Ryan Em C. DalmanMD MBA - 070070 “Co-co-co-com Bulsyon!” “ehem…”](https://reader030.vdocuments.site/reader030/viewer/2022032722/56649ce15503460f949ac143/html5/thumbnails/49.jpg)
Treatment
Antipyretic use Used to lower fever and should not be relied
upon to prevent the recurrence of febrile seizures
Antiepileptic drug use (continuous anticonvulsant) Not recommended in children after a simple
febrile seizure. It can reduce the recurrence of febrile
seizures, but its adverse side effects do not warrant their use in this benign disorderCPG on First Simple Febrile
Seizure
![Page 50: Ryan Em C. DalmanMD MBA - 070070 “Co-co-co-com Bulsyon!” “ehem…”](https://reader030.vdocuments.site/reader030/viewer/2022032722/56649ce15503460f949ac143/html5/thumbnails/50.jpg)
Treatment
Antiepileptic drug use (intermittent anticonvulsant) Not recommended for the prevention of
recurrent febrile seizures There is no difference in the risk of
seizure recurrence in children receiving intermittent diazepam and placebo

Prognostic Evaluation
Electroencephalogram (EEG) Should not be routinely requested in

does not change the recommendation the use of anticonvulsants
