Efficacy of Liposomal Bupivacaine for Transversus Abdominis Plane Block

Sponsor: Tianjin First Central Hospital

Summary

This is a single-center, randomized, single-blind, parallel-group clinical trial. The study aims to compare the analgesic efficacy of liposomal bupivacaine versus ropivacaine for transversus abdominis plane (TAP) block in patients undergoing laparoscopic cholecystectomy. Eligible participants will be randomly assigned to receive either liposomal bupivacaine or ropivacaine for TAP block during surgery. The primary outcome is the dynamic NRS pain score at 24 hours after surgery. Secondary outcomes include static and dynamic NRS pain scores at multiple time points, QoR-15 recovery quality, time to first rescue analgesia, analgesic consumption, gastrointestinal function recovery, length of hospital stay, and adverse events. Participants will be followed up to 3 months after surgery to evaluate the incidence of chronic post-surgical pain (CPSP). All participants will receive routine clinical care, and participation is voluntary.
