Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-65 scheduled for robotic sleeve gastrectomy who can provide informed consent.

Probably not a fit

Patients with a history of substance abuse, ongoing narcotic use, or contraindications to the study drugs may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of Zynrelef, a combination of bupivacaine and meloxicam, versus Exparel, an injectable liposomal bupivacaine, for managing postoperative pain following robotic sleeve gastrectomy. Participants will be randomly assigned to receive either Zynrelef or Exparel at the closure site of their surgery. The study will assess pain levels using a numerical rating scale for up to 72 hours post-surgery, along with tracking total opioid use. The goal is to determine which method provides better pain control and to analyze the associated costs of the medications used.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative pain management strategies for patients undergoing robotic sleeve gastrectomy.

How similar studies have gone: Previous studies have shown promise in using extended local anesthesia for postoperative pain control, suggesting potential success for this approach.
