What this trial studies

This clinical trial investigates the use of intravenous melatonin to prevent postoperative agitation and emergence delirium in children aged 1-6 years undergoing elective surgeries with general anesthesia. The study aims to determine the safety and efficacy of melatonin in reducing behavioral disturbances that can occur during early recovery from anesthesia. Participants will receive melatonin or an isotonic sodium chloride solution during their procedure, and the outcomes will be assessed to evaluate the effectiveness of melatonin in this context.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 1-6 years scheduled for elective surgeries lasting at least 30 minutes under general anesthesia.

Not a fit: Patients with known allergies to melatonin or those currently taking melatonin daily may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of postoperative agitation and improve recovery experiences for children.

How similar studies have performed: Previous studies have shown promising results with melatonin in reducing emergence agitation in pediatric patients, indicating potential for success in this trial.
