Investigating genetic factors affecting postoperative pain in children

COMT and OPRM1 Polymorphisms and Their Effect on Post-Operative Pain in Children Undergoing Orthopedic, Abdominal, Thoracic, and Plastic Surgeries.

Observational American University of Beirut Medical Center · NCT06777875

This study is trying to see if certain genes affect how much pain children aged 8 to 18 feel after surgery and how well pain medicine works for them.

What this trial studies

This observational study aims to explore the impact of specific genetic variations, namely the A118G SNP in the OPRM1 gene and various SNPs in the COMT gene, on postoperative pain experiences in children aged 8 to 18 undergoing different types of surgeries. By assessing pain scores, sedation levels, and opioid requirements, the study seeks to understand how these genetic factors may influence pain management outcomes. A cohort of 200 children will be recruited, and their genetic profiles will be analyzed to determine correlations with pain perception and analgesic needs.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 8 to 18 who are scheduled for orthopedic, abdominal, thoracic, or plastic surgeries.

Not a fit: Patients with psychiatric disorders, severe pain conditions requiring surgical treatment, or those receiving regional anesthesia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized pain management strategies for children based on their genetic profiles.

How similar studies have performed: While the investigation of genetic factors in pain management is an emerging field, similar studies have shown promising results in understanding pain sensitivity and opioid response, indicating potential for success.
