What are the recommended benzodiazepine rescue routes and dosing considerations for pediatric acute seizure management?

• A. IV Lorazepam 0.05-0.1 mg/kg (max 4 mg) or IV Diazepam 0.15-0.2 mg/kg; Intranasal Midazolam 0.2 mg/kg; Repeat once if still seizing after 5 minutes
• B. Oral Lorazepam 0.1 mg/kg
• C. Rectal Diazepam 0.5 mg/kg
• D. Intramuscular Phenobarbital

Answer: (A)

In pediatric acute seizures, the goal is rapid, reliable seizure control using a benzodiazepine route that delivers the drug quickly and is practical to administer. The best rescue plan combines a fast-acting IV option if IV access is available (lorazepam 0.05–0.1 mg/kg, max 4 mg, or diazepam 0.15–0.2 mg/kg), with a non-IV option for ease of use (intranasal midazolam 0.2 mg/kg). A single repetition is recommended if the seizure persists after about 5 minutes. This approach provides swift onset when IV access is possible and an easy, effective alternative when it isn’t, optimizing both speed and practicality for caregivers and clinicians. Oral lorazepam is too slow for acute control, rectal diazepam is less preferred due to absorption variability and social practicality, and intramuscular phenobarbital is not a first-line rescue due to slower action and safety concerns.
