What this trial studies

This study investigates the effectiveness of using a nociception level monitor to guide the administration of remifentanil, a short-acting opioid, during general anesthesia in children aged 3-16 years. The goal is to determine if this approach can reduce postoperative pain, opioid consumption, and agitation compared to standard care. Participants will receive standard analgesia and antiemetics alongside the monitored opioid dosing. The study aims to provide insights into the clinical benefits of nociception level-guided analgesia in a pediatric population.

Who should consider this trial

Good fit: Ideal candidates are children aged 3-16 years scheduled for surgery requiring intraoperative opioid administration.

Not a fit: Patients with mental disorders or impairments that affect cooperation, as well as those with known arrhythmias or allergies to the study medications, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved pain management and reduced opioid use in children after surgery.

How similar studies have performed: While nociception level-guided analgesia has not been previously assessed in children, similar approaches in adults have shown promising results.
