Febrile seizures: emergency medicine perspective

Area of Science:

• Pediatric Neurology
• Clinical Evidence Synthesis
• Seizure Management

Background:

• Febrile seizures are common in childhood.
• Accurate assessment is crucial for appropriate management and predicting outcomes.

Purpose of the Study:

• To review current evidence on evaluating febrile seizures in acute care settings.
• To identify needs for outpatient assessment and long-term outcome predictors.
• To synthesize new evidence on diagnostic and therapeutic interventions.

Main Methods:

• Systematic review of recent evidence.
• Analysis of diagnostic utility (lumbar puncture, neuroimaging, EEG).
• Evaluation of prophylactic and therapeutic interventions (antipyretics, antiepileptics, diazepam).

Main Results:

• Limited utility established for lumbar puncture, emergent neuroimaging, and follow-up EEG.
• Low yield demonstrated for antipyretic prophylaxis and intermittent antiepileptic drug use.
• Growing evidence on the genetic basis of febrile seizures and vaccine-related seizures.

Conclusions:

• Routine diagnostic testing for simple febrile seizures is discouraged.
• Clinical acumen is paramount for identifying children requiring extensive evaluation.
• Evidence and guidelines for complex febrile seizures and out-of-hospital diazepam treatment are lacking.
