What this trial studies

This clinical trial investigates the effectiveness of combining oral midazolam with intranasal esketamine to alleviate preoperative anxiety in children aged 2-6 years. The study aims to determine if this combination provides better sedation outcomes compared to using each medication alone. Participants will be assessed using various scales to measure anxiety levels, sedation scores, and recovery times. The trial will involve children scheduled for lower abdominal and perineal surgeries with a short expected operation time.

Who should consider this trial

Good fit: Ideal candidates are children aged 2-6 years with ASA physical status I or II, scheduled for short lower abdominal or perineal surgeries.

Not a fit: Patients with gastrointestinal, cardiovascular, or endocrine dysfunction, or those with contraindications to the medications will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve preoperative sedation and reduce anxiety-related complications in pediatric patients.

How similar studies have performed: While the combination of these medications is being explored, the specific approach of using both oral midazolam and intranasal esketamine together is relatively novel.
