What this trial studies

This study aims to evaluate the effectiveness of preoperative oral pregabalin versus intraoperative intravenous fentanyl in managing postoperative pain for patients undergoing diagnostic laparoscopic gynecologic surgery. Patients will be randomly assigned to receive either pregabalin or a placebo before surgery, while the control group will receive fentanyl during the procedure. The goal is to assess the analgesic effects and opioid-sparing potential of pregabalin, which may lead to reduced side effects associated with opioid use. The study will involve 80 participants divided into two groups, each receiving different interventions.

Why it matters

Potential benefit: If successful, this study could provide a safer and more effective pain management option for patients undergoing surgery, reducing reliance on opioids.

How similar studies have gone: Previous studies have shown promising results with pregabalin in reducing postoperative pain, indicating that this approach may be effective.
