Comparing pain control methods after tonsil surgery in children

Single-Dose Intraoperative Methadone for Pain Management in Pediatric Tonsillectomy: A Randomized Double Blind Clinical Trial

PHASE4 · Duke University · NCT06576830

This study is testing whether long-lasting pain medicine like methadone works better than short-lasting options like fentanyl and hydromorphone for controlling pain in kids and teens after tonsil surgery.

What this trial studies

This study aims to evaluate the effectiveness of long-acting opioids, specifically methadone, versus short-acting opioids like fentanyl and hydromorphone for managing postoperative pain in children and adolescents undergoing tonsillectomy. It is a randomized, double-blind, parallel-group trial that will include participants aged 3 to 17 years, who will be assigned to either methadone or short-acting opioids. The study will monitor pain management outcomes and potential side effects through daily surveys and follow-up calls for six months post-surgery.

Who should consider this trial

Good fit: Ideal candidates are children and adolescents aged 3 to 17 years scheduled for elective tonsillectomy with or without adenoidectomy.

Not a fit: Patients with chronic pain disorders, severe sleep apnea, or those requiring admission to the Pediatric Intensive Care Unit may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for pediatric tonsillectomy patients, reducing the need for rescue opioids.

How similar studies have performed: Previous studies have explored opioid management in postoperative settings, but this specific comparison of methadone versus short-acting opioids in a pediatric population is relatively novel.
