When are seizures considered medical emergencies in prehospital care?

• A. If lasting more than 1 minute
• B. If lasting more than 3 minutes
• C. If lasting more than 5 minutes
• D. If preceded by fever

Answer: (C)

Prolonged seizure activity is the main trigger for a prehospital medical emergency. When a seizure lasts more than five minutes, ongoing convulsions are unlikely to stop on their own and the risk of brain injury, hypoxia, acidosis, and aspiration increases. In the field, this threshold prompts rapid airway management, oxygenation, and urgent transport to an emergency department, since timely treatment is crucial to prevent status epilepticus and its complications.

Most seizures end within a couple minutes on their own, so shorter durations (like around one to a few minutes) are not automatically emergencies. Fever preceding a seizure may point to a febrile seizure in children, which is often benign and brief, so the duration of the seizure itself is the more important emergency indicator.
