The Efficacy and Safety of Liposomal Bupivacaine for Rhomboid Intercostal Nerve Block in Relieving Postoperative Pain After Video-assisted Thoracoscopic Surgery

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.In recent years, multimodal postoperative analgesia protocols have been increasingly adopted in clinical practice. The Rhomboid intercostal block (RIB), as a novel regional anesthesia technique within the multimodal analgesia framework, has been widely utilized in various thoracic surgical procedures. Liposomal bupivacaine, an innovative long-acting sustained-release amide local anesthetic, provides prolonged analgesia for up to 72 hours. However, its efficacy and safety in video-assisted thoracoscopic surgery (VATS) have not yet been fully validated. Based on this premise, the present study aims to evaluate and compare the clinical outcomes of ultrasound-guided Rhomboid intercostal block (RIB) utilizing liposomal bupivacaine combined with conventional bupivacaine for postoperative pain management in patients undergoing VATS.
