Scope of this summary
Children approximately 6 through 60 months with a seizure associated with fever and no established central nervous system infection, prior afebrile seizure or provoking metabolic cause. The current clinical source is Nationwide Children鈥檚 June 2024 institutional pathway; no current national replacement for the automatically expired older AAP febrile-seizure guidance was used as claim evidence. Neonates, infants younger than the pathway age and children with known epilepsy need different pathways.

The Bottom Line
- First stop an ongoing prolonged seizure and support airway, breathing and circulation. A seizure lasting five minutes or longer should activate the local emergency rescue-medication or status-epilepticus pathway rather than waiting for spontaneous resolution.
- Classify the event after stabilization: a simple febrile seizure is generalized, lasts less than 15 minutes and occurs once in 24 hours; focal features, duration of 15 minutes or more or recurrence within 24 hours makes the event complex.
- Identify the source of fever and assess specifically for meningitis or encephalitis. Lumbar puncture is driven by age, clinical illness, meningeal findings and infection risk, not performed routinely after every simple seizure.
- A neurologically healthy child who returns to baseline after a simple febrile seizure usually does not need routine EEG, neuroimaging or broad seizure-focused laboratory testing; direct testing toward the fever source and concerning findings.
- Explain that antipyretics can improve comfort but do not reliably prevent another febrile seizure, and give caregivers practical seizure first aid and a clear emergency threshold rather than promising prevention.

Practical clinical workflow
1
Establish duration, focality, number in 24 hours, fever timing, immunization, recent antibiotics, toxic exposure, trauma, development, prior febrile or afebrile events and family seizure history using a witness account or video when available.
2
Check airway, oxygenation, circulation, temperature and bedside glucose; treat an active prolonged seizure using the institutional weight-based rescue protocol and reassess for respiratory depression after medication.
3
After the event, examine mental status, neck, skin, hydration, ears, throat, lungs, abdomen and neurologic function, and investigate the infectious source according to age and findings.
4
For a simple event with prompt return to baseline, avoid reflexive EEG, CT, MRI and laboratory panels. For a complex event, persistent altered state, focal deficit or atypical age, individualize testing with emergency, pediatric and neurology input.
5
Before discharge, demonstrate side-positioning and airway safety, advise caregivers not to restrain the child or place anything in the mouth, specify when to call emergency services and arrange pediatric follow-up after a first or complex event.

Safety boundaries and escalation
- Ongoing seizure at five minutes, breathing difficulty, cyanosis, serious injury or failure to regain expected responsiveness requires emergency medical services and the local status-epilepticus pathway.
- Neck stiffness, petechiae or purpura, marked lethargy, persistent irritability, bulging fontanelle or a concerning young infant requires urgent meningitis and invasive-infection evaluation.
- Focal deficit, focal seizure, repeated events in 24 hours, duration of 15 minutes or more, developmental regression or an event outside the typical age range needs individualized neurologic assessment rather than simple-event reassurance.
- Do not use cold-water immersion, alcohol rubs, forceful restraint or an object in the mouth during a seizure; protect from injury, place on the side when possible and time the event.

Localization
Nationwide Children鈥檚 pathway is a current institutional US implementation and is labelled as such. Emergency-service thresholds, rescue formulations, febrile-infant testing and neurology referral vary locally.
