Analgesic Efficacy Between Liposomal Bupivacaine and Bupivacaine Hydrochloride in Intercostal Nerve Block for Thoracic Surgery: A Multicenter Randomized Controlled Trial
This randomized controlled trial evaluates the analgesic effects of liposomal bupivacaine compared to bupivacaine hydrochloride in intercostal nerve block for patients undergoing thoracoscopic lung surgery. Postoperative pain remains a significant issue in thoracic procedures, often leading to complications like pneumonia or delayed recovery. The investigators hypothesize that liposomal bupivacaine, with its extended-release properties, will provide superior pain relief beyond 24 hours compared to standard bupivacaine or no block. Participants will be randomized 1:1:1 to liposomal bupivacaine group , bupivacaine hydrochloride group , or control group . Primary outcome is the area under the curve of pain scores from 25-72 hours post-surgery. Secondary outcomes include opioid consumption, recovery quality (QoR-15), and other complications.
