Who could benefit from this research

Could help

Adults undergoing surgical procedures experiencing moderate-to-severe postoperative pain lasting several days.

Less likely to help

Patients with contraindications to bupivacaine or local anesthesia, or those requiring different pain management strategies.

What this research studies

This project aims to deliver long-lasting pain relief after surgery with an injectable gel that releases local anesthetic over multiple days. It focuses on patients undergoing various surgical procedures who typically need pain control beyond the first day. By avoiding opioids, it seeks to reduce opioid-related side effects and risks while keeping patients comfortable during recovery. The approach addresses challenges in maintaining effective drug levels in tissue around the surgical site to sustain analgesia. If successful, it could simplify recovery and decrease the likelihood of persistent opioid use.

Why it matters

Potential benefit: Could provide multi-day, opioid-free pain control after surgery, reducing opioid-related risks.

How similar studies have gone: Prior approaches have struggled to sustain analgesia beyond 24 hours; this project proposes a new extended-release gel.
