Liposomal bupivacaine to reduce pain after VATS

Is this trial a fit for you?

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

What this trial studies

This interventional trial compares incision-site local injection of standard bupivacaine to liposomal bupivacaine combined with bupivacaine in adults undergoing elective video-assisted thoracoscopic lobectomy or wedge resection. Participants receive the assigned local anesthetic at the surgical incision and are followed after surgery for pain scores, opioid consumption, and postoperative complications. Liposomal bupivacaine is a sustained-release formulation intended to provide analgesia for up to 72 hours, which the trial will test against conventional bupivacaine infiltration. Outcomes will focus on acute postoperative pain control and measures related to recovery and adverse events.
