What this trial studies

This clinical trial evaluates the effects of preemptive oral pregabalin on postoperative pain management in obese patients undergoing laparoscopic sleeve gastrectomy. Participants will be divided into two groups: one receiving pregabalin and the other receiving a placebo. The study aims to assess the impact of pregabalin on pain scores and opioid use, as well as its effect on intraoperative hemodynamic stability. The hypothesis is that pregabalin will reduce the need for opioids and improve overall postoperative outcomes.

Who should consider this trial

Good fit: Ideal candidates are obese patients with a BMI over 40 or over 35 with comorbidities who are scheduled for laparoscopic sleeve gastrectomy.

Not a fit: Patients who refuse participation, have allergies to the study medication, or have end-stage organ failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved pain management and reduced opioid use in obese patients after surgery.

How similar studies have performed: Previous studies have indicated that pregabalin can effectively reduce opioid requirements in postoperative settings, suggesting potential success for this approach.
