A child has a seizure lasting 10 minutes. Which route of medication is commonly used in the field to terminate a prolonged pediatric seizure?

• A. Intranasal Midazolam
• B. Oral Diazepam
• C. Intravenous Lorazepam
• D. Intramuscular Midazolam

Answer: (A)

This question tests choosing a noninvasive, rapid-acting way to stop a prolonged seizure in a child in the field. In acute pediatric seizures, benzodiazepines are the first-line agents, and how you administer them matters because every minute counts.

Intranasal midazolam is favored because it delivers the medicine quickly through the nasal mucosa, giving rapid CNS effects without needing IV access. In a marching seizure, that speed and ease of administration reduce the time to seizure termination and minimize the stress and delays of poking for a vein or preparing an injection. The route is practical for EMS providers and caregivers, and it works well in children who may resist injections.

Oral diazepam is less reliable in this setting because its absorption is slower and variable, and the child may not be able to swallow safely during a seizure. Intravenous lorazepam can be effective, but establishing IV access during ongoing convulsions is often difficult and time-consuming, delaying treatment. Intramuscular midazolam is a valid alternative if intranasal administration isn’t available, but it still involves a needle and may be less convenient than a quick nasal spray in the field.

So, giving midazolam intranasally provides the fastest, most dependable route to terminate a prolonged pediatric seizure in the prehospital environment.
