The Effect of Bupivacaine Liposomes on Postoperative Pain in Lung Transplant Patients After Intercostal Nerve Block: a Randomized Controlled Study
The goal of this clinical trial is to evaluate the efficacy and safety of liposomal bupivacaine for postoperative analgesia in adult patients undergoing lung transplantation. The main questions it aims to answer are:
Does liposomal bupivacaine reduce postoperative opioid consumption after lung transplantation? Does liposomal bupivacaine relieve postoperative pain without increasing adverse events?
Researchers will compare patients receiving liposomal bupivacaine combined with bupivacaine hydrochloride with patients receiving bupivacaine hydrochloride alone to see whether liposomal bupivacaine provides better postoperative analgesia and reduces opioid requirements after lung transplantation.
Participants will:
Receive lung transplantation under standard perioperative care. Receive intercostal nerve block with either liposomal bupivacaine combined with bupivacaine hydrochloride or bupivacaine hydrochloride alone.
Be assessed for postoperative opioid consumption, pain scores, recovery-related outcomes, and adverse events after surgery.
