Define pediatric status epilepticus and outline first-line emergency treatment.

• A. Persistent seizure activity lasting ≥5 minutes or repeated seizures without recovery between them; first-line benzodiazepine
• B. Seizures lasting ≥30 minutes
• C. Any seizure upon awakening
• D. Nonconvulsive status epilepticus

Answer: (A)

Pediatric status epilepticus is defined by ongoing seizure activity lasting five minutes or longer, or by two or more seizures without full recovery between them. This 5-minute threshold matters because the brain can progressively become more excitable and injury risk rises the longer a seizure continues, so initiating treatment quickly is crucial to stop the event.

The first-line emergency treatment is a benzodiazepine given right away to halt seizure activity. In hospital, intravenous lorazepam is commonly used at about 0.1 mg/kg (maximum around 4 mg). If IV access isn’t yet available, intramuscular midazolam at 0.2 mg/kg (up to 10 mg) provides rapid effect. In home or prehospital care, rectal diazepam at 0.5 mg/kg (up to 10 mg) is a practical option. If seizures persist after the initial benzodiazepine, treatment typically escalates to other anticonvulsants and supportive care.

Seizures lasting 30 minutes would still be considered prolonged, but the defining threshold for status epilepticus is five minutes or longer. Nonconvulsive status epilepticus is a type of status epilepticus, not the general definition, and a seizure upon awakening doesn’t define status epilepticus.
