Efficacy of Liposomal Bupivacaine for Transversus Abdominis Plane Block

2026年5月11日 更新者：Lili Jia、Tianjin First Central Hospital

Liposomal Bupivacaine Versus Ropivacaine for Transversus Abdominis Plane Block in Laparoscopic Cholecystectomy: A Randomized, Single-Blind, Parallel-Group Trial

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.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Postoperative dynamic NRS pain score at 24 hours
大体时间：24 hours after surgery
Postoperative pain intensity under dynamic conditions (e.g., coughing or deep breathing) will be assessed using the Numerical Rating Scale (NRS, 0-10, where 0 = no pain and 10 = worst imaginable pain).
24 hours after surgery

次要结果测量

结果测量
措施说明
大体时间
Postoperative NRS pain scores at different time points
大体时间：24, 48, and 72 hours after surgery
NRS scores at 24, 48, and 72 hours post-surgery while at rest; NRS scores at 48 and 72 hours while active
24, 48, and 72 hours after surgery
Postoperative recovery quality (QoR-15 scale)
大体时间：24, 48, and 72 hours after surgery
Postoperative recovery quality will be evaluated using the 15-item Quality of Recovery (QoR-15) scale at 24 hours after surgery. The total score ranges from 0 to 150, with higher scores indicating better recovery quality.
24, 48, and 72 hours after surgery
Time to first rescue analgesia
大体时间：Up to 72 hours after surgery
The time from the end of surgery to the first request for rescue analgesia (e.g., opioid or non-opioid analgesics) will be recorded（background pain is excluded）.
Up to 72 hours after surgery
Total postoperative analgesic consumption within 72 hours
大体时间：72 hours after surgery
Total amount of rescue analgesics (e.g., opioids, NSAIDs) used by each patient within 72 hours after surgery will be calculated and converted into equivalent doses.
72 hours after surgery
Gastrointestinal function recovery
大体时间：Postoperatively, through hospital discharge, up to 7 days after surgery
Time to first flatus and time to first defecation, measured from the end of surgery.
Postoperatively, through hospital discharge, up to 7 days after surgery
Postoperative length of hospital stay
大体时间：Postoperatively, through hospital discharge (up to 7 days)
The total number of days from surgery to hospital discharge will be recorded.
Postoperatively, through hospital discharge (up to 7 days)
Incidence of adverse events
大体时间：Postoperatively, through hospital discharge, and at follow-up (up to 7 days after surgery)
Adverse events including nausea, vomiting, dizziness, local anesthetic toxicity, and neurological complications will be recorded and compared between groups during hospitalization and follow-up.
Postoperatively, through hospital discharge, and at follow-up (up to 7 days after surgery)

其他结果措施

结果测量
措施说明
大体时间
Incidence of chronic post-surgical pain (CPSP) at 3 months
大体时间：3 months after surgery
The incidence of chronic post-surgical pain will be assessed via telephone follow-up.Incidence of chronic post-surgical pain (CPSP) , defined as persistent pain (NRS ≥ 1) at the surgical site lasting ≥ 3 months after laparoscopic cholecystectomy, excluding pain caused by other etiologies.
