II. Determine the effect of prehospital therapy on the incidence of status epilepticus at the subsequent emergency department admission.

III. Establish whether prehospital therapy alters hospital management of these patients and ultimately affects patient outcome.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No
