Flashcards in Paeds: Febrile Convulsions Deck (15)
A febrile seizure is a seizure accompanied by a fever in the absence of intracranial infection due to bacterial meningitis or viral encephalitis.
Occur in 3% of children between the ages of 6 months and 5 years
10% risk if the child has a first-degree relative with febrile seizures
19q and 19q 13-21 (don’t need to know)
The seizure usually occurs early in a viral infection when the temperature is rising rapidly
Usually brief and are generalised tonic-clonic seizures
30-40% will have further febrile seizures
• More likely if the child is younger
• Short the duration of illness before the seizures
• The lower the temperature at the time of seizure
• Positive family history.
Simple febrile seizures do not cause brain damage; the child’s subsequent intellectual performance is the same as in children who do not experience a febrile seizure.
There is a 1-2% chance of developing epilepsy, similar to the risk for all Children.
Simple versus complex
Post ictal drowsiness (nothing else)
More than 1 in 24hours
Post ictal seizures or movements
Find out the cause Rule/out meningitis/encephalitis
Slight increase risk however comes with a range of things like
- Other picture going on e.g. delayed dev milestones
- Fx of epilepsy
- Should focus on the cause of the fever, which is usually a viral illness, but a bacterial infection including meningitis should always should always be considered.
- Infection screen may be necessary
o Blood cultures
o Metabolic: Glucose
o Electrolyte disturbance (Ca and MG)
o Toxicology cause?
o Urine culture
o Lumbar puncture for CSF
