The Efficacy and Safety of Liposomal Bupivacaine in Relieving Postoperative Pain After Video-assisted Thoracoscopic Surgery
China100 participantsStarted 2026-03-02
Plain-language summary
Video-assisted thoracoscopic surgery (VATS) is less invasive compared to traditional thoracotomy. It is reported that the incidence of acute pain following VATS exceeds 80%. Inadequate postoperative analgesia may trigger a series of adverse physiological stress responses, increase the occurrence of postoperative complications, and affect the rehabilitation process.If acute pain is not managed promptly and sufficiently, nearly one-quarter of patients may develop chronic pain, impacting normal life and sleep quality after discharge. Local infiltration anesthesia at the incision site is one of the simplest, safest, and most effective methods for preventing postoperative incision pain. Liposomal bupivacaine(LB) is a novel, long-acting, sustained-release amide-type local anesthetic, providing localized analgesic effects for up to 72 hours. Some researchers have reported the analgesic effects of LB VS traditional local anesthetics infiltration, but the current research results are highly heterogeneous. More prospective studies are needed to evaluate whether LB infiltration is superior to the traditional local anesthetics for the management of postoperative pain. The investigators designed this study to compare the analgesic effect of using LB plus bupivacaine for local infiltration with bupivacaine along for patients after VATS.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
