- Seizures are followed by a period of confusion and sleepiness which slowly goes away
Complex febrile seizures:
- Last longer than 15 minutes
- Occur more than once within 24 hours
- Convulsions which affect only part the body
- A fever, usually above 102°F (38.9ºC)
- Convulsion—jerking or stiffening muscles
- Abnormal eye movements
- Coarse breathing sounds during the convulsion
- Loss of consciousness
- Loss of bladder or bowel control
- Brief period of drowsiness or confusion following a seizure
- Unless the doctor has told you otherwise, call for emergency medical services.
- Protect your child from physical injury. Place your child on the floor or bed away from any hard or sharp objects.
- Protect your child's airway. Do not place anything in the mouth during the convulsion. Turn the child’s head or body to the side. This will allow saliva or vomit to drain from the mouth.
- Watch the time. The length of the convulsions should be less than 5 minutes.
