Hi L.,
My daughter had her first seizure a year ago when she was 4.5 and her 2nd this past August. After the first, she had several EEGs and the neurologist determined that she does not have an underlying seizure condition (i.e., epilepsy, etc.). They determined the cause was a rapid change in temperature, i.e., febrile seizure. That was the case again with her 2nd seizure. She is also on Trileptal (for something else) so we thought we had an added insurance policy against seizures, but not so. The ER doc explained that Trileptal would protect her if she had a seizure condition but NOT if she is prone to febrile seizures. We do feel that the Trileptal helped at least, because the second seizure lasted only a couple of minutes and didn't require intervention vs. an hour for the first and a truckload of Atavan that shut down her central nervous system.
What we've learned from our experiences is that children with febrile seizures outgrow them when their body mass becomes heavy enough (usually around 5-8 yrs. old) that their body temperature cannot change as rapidly. With febrile seizures, it's not necessarily how high the temperature goes, but how quickly it rises. We also learned to treat a rise in temperature aggressively: Treat IMMEDIATELY and with an appropriate dose. Check with your pediatrician for the appropriate dose of Advil (ibuprofen) and Tylenol (acetaminophen) for your child's weight. The doses on the packages are conservative estimates. We check our daughter's temp repeatedly after we notice a fever to make sure that the medicine is working. You can alternate Advil and Tylenol more frequently than giving just one and waiting the 4-6 hours for the next dose. We also learned the first aid for seizures: Clear the surroundings to make sure she's safe, roll her on her side so she doesn't aspirate (breathe in) her frothiness at the mouth. (The first time, she aspirated, needed to be intubated, and ended up with pneuomonitis and a 7-day hospital stay.) Her pedi prescribed Diastat (a suppository) to help stop the seizure if she can't come out of it on her own within a few minutes.
I know it's soooo very scary when it happens. Try to stay calm and keep your wits about you. Our pedi and neurologist have assured us that there is no lasting effect and/or damage to the brain. Feel free to contact me if you want to know more. Good luck to you and your family! May you all have a healthy winter!
