Management of a 2-Year-Old with Fever and Seizure
Reassure the parents and identify the source of fever—this is a simple febrile seizure requiring no EEG, no head CT, and no antiepileptic drugs. 1, 2
Immediate Assessment Priorities
The primary objective is to identify the source of fever, particularly ruling out serious bacterial infections like meningitis and urinary tract infection. 2, 3
Critical Exclusion Criteria
- Assess for meningeal signs: Check for altered mental status, neck stiffness, excessive drowsiness, or irritability—any of these mandate lumbar puncture regardless of age 2, 4
- Evaluate general appearance: A child with toxic appearance, poor feeding, or incomplete recovery after one hour requires more aggressive evaluation 2, 3
- At 2 years of age with no neurological deficits and presumed simple febrile seizure, lumbar puncture is not routinely indicated unless clinical suspicion for CNS infection exists 2, 3
Essential Diagnostic Workup
- Obtain urinalysis: Urinary tract infection is the most common serious bacterial infection in febrile children, with 5-7% prevalence 3
- Assess for respiratory signs: If tachypnea, retractions, or crackles are present, obtain chest radiography 2
- Blood glucose if seen during seizure 1
What NOT to Do
Do not order routine EEG—it is explicitly listed as inappropriate investigation for simple febrile seizures. 1
Do not order head CT—neuroimaging is not indicated for simple febrile seizures without focal neurological deficits. 1
Do not start maintenance antiepileptic drugs—the potential toxicities outweigh the relatively minor risks of simple febrile seizures. 1
Fever Management
- Administer paracetamol (acetaminophen) for comfort, not seizure prevention: Antipyretics improve comfort but do not prevent febrile seizure recurrence 1, 2
- Avoid physical cooling methods: Fanning, cold bathing, and tepid sponging cause discomfort and are not recommended 1, 2
- Ensure adequate hydration to prevent dehydration 1
Prognosis and Parent Education
The prognosis is excellent—risk of subsequent epilepsy after a simple febrile seizure is only 2.5%. 1
Key Points for Parents
- Recurrence risk is approximately 30% overall, but increases to 50% in children under 2 years of age 1, 2, 3
- Provide home management instructions: Position child on side during seizure, do not place anything in mouth, seek emergency care if seizure lasts >5 minutes 3
- Warning signs requiring immediate return: Worsening general condition, skin rash/petechiae, respiratory distress, feeding refusal, excessive irritability or somnolence 2
Common Pitfalls to Avoid
- Do not assume all febrile seizures are benign without proper assessment: Up to 1 in 6 children with meningitis present with seizures, and one-third may lack meningeal signs 4
- Do not overlook urinary tract infection: This is easily missed without urinalysis 3
- Do not prescribe prophylactic anticonvulsants: Evidence shows no benefit for simple febrile seizures, and toxicity risks are significant 1
