A 4-year-old child with known epilepsy is brought with generalized convulsions lasting 20 minutes. IV access is unavailable. Which is the most appropriate immediate intervention according to current guidelines?

• A Rectal diazepam 0.5 mg/kg
• B Intranasal midazolam 0.2 mg/kg ✓
• C Oral clonazepam 0.1 mg/kg
• D IM phenobarbital 20 mg/kg

Explanation

Intranasal midazolam (0.2 mg/kg) is the preferred route when IV access is unavailable in a child with status epilepticus, providing rapid CNS absorption comparable to IV. Buccal midazolam is an equally acceptable alternative. Rectal diazepam is effective but less acceptable socially and has slower peak effect than intranasal midazolam. Oral benzodiazepines during an active seizure risk aspiration. IM phenobarbital takes too long to achieve therapeutic CNS levels for acute termination.
