    ObjectivesThoracic surgery can cause significant pain, and multiple strategies have been developed to control pain after surgery. We compared 2 bupivacaine formulations given intraoperatively: bupivacaine with epinephrine (1,200,000) or liposomal bupivacaine.MethodsThis was a randomized, open-label study (NCT03560362). Eligible patients were adults scheduled for a minimally invasive lung procedure. Incision sites were injected with bupivacaine with epinephrine or liposomal bupivacaine before incision, and each intercostal space was injected with 1 mL of bupivacaine with epinephrine or liposomal bupivacaine entering the thoracic cavity. Patient-controlled analgesia was initiated in the recovery room. Pain was recorded using a visual analog scale. The primary outcome was the amount of narcotics taken during the postoperative hospital stay.ResultsWe recruited 50 patients; 25 received bupivacaine with epinephrine, and 25 received liposomal bupivacaine. The treatment groups were similar in age, histology, and procedure performed. There were no statistical differences between the treatment groups in the amount of narcotics required during the hospital stay (36.3 mg for bupivacaine and 38 mg for liposomal bupivacaine) or in pain assessed the day of surgery (5 and 5), the first day (3.5 and 2.3), second day (3 and 2.6), 2 weeks (0 and 1), or 3 months (0 and 0) postoperatively. Hospital length of stay and complications were also similar.ConclusionsIn a small, randomized study, we did not find significant differences between bupivacaine with epinephrine or liposomal bupivacaine in mitigating pain after minimally invasive lung resection. We currently favor using the less expensive nonliposomal bupivacaine preparations until additional data are available.Copyright © 2020 The American Association for Thoracic Surgery.
