The Effect of Preoperative Oral Pregabalin and Intraoperative Fentanyl on Postoperative Analgesia in Diagnostic Laparoscopic Gynecologic Surgery: a Comparative Study

Early Phase 1 Interventional Ain Shams University · NCT05150795

This study is testing whether taking pregabalin before surgery can help manage pain after laparoscopic gynecologic surgery better than using fentanyl during the procedure.

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.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults classified as ASA physical status I who are scheduled for diagnostic laparoscopic gynecologic surgery.

Not a fit: Patients with a history of chronic pain, those taking sedatives or analgesics, or individuals with a history of drug/alcohol abuse may not benefit from this study.

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