What this trial studies

This clinical trial investigates the effects of oxycodone combined with pregabalin on chronic postoperative pain in patients undergoing spinal surgery. It aims to determine the efficacy and safety of this combination compared to other treatment regimens, including placebo. The study employs a randomized-controlled, factorial design to assess how well these medications can manage pain that persists after surgery. The trial seeks to fill a gap in current pain management strategies for patients experiencing chronic pain following spinal procedures.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for elective spinal surgery and meet specific health criteria.

Not a fit: Patients with a history of drug abuse, severe health conditions, or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management for patients recovering from spinal surgery.

How similar studies have performed: While oxycodone is commonly used for acute pain, the combination with pregabalin for chronic postoperative pain is relatively novel and has not been extensively tested.
