What this trial studies

This clinical trial investigates the effectiveness of intravenous dexamethasone in preventing migraine recurrence in children aged 8 to 17 who present with acute migraines in the emergency department. The study employs a randomized, double-blind, placebo-controlled design, where participants receive either dexamethasone or a placebo following standard migraine treatment. The trial aims to identify risk factors for migraine relapse after discharge and is conducted at CHU Ste-Justine, a tertiary care pediatric hospital. The study protocol includes the administration of metoclopramide or prochlorperazine, depending on availability, to manage severe migraine symptoms.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 8 to 17 who present with a diagnosis of acute migraine and require intravenous treatment due to the severity of their condition.

Not a fit: Patients with known allergies to the study drugs, contraindications to corticosteroids, or those already on corticosteroids may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the rate of migraine relapse in children, improving their quality of life and reducing emergency department visits.

How similar studies have performed: While dexamethasone has shown effectiveness in preventing migraine recurrence in adults, this approach in pediatric populations is novel and has not been extensively tested.
