Comparing Two Ultrasound-Guided Nerve Block Methods for Pain Relief After Lung Cancer Surgery

What this Trial Is About

Researchers are evaluating the effects of two different nerve block methods, retro-superior costotransverse ligament space block retro-SCTLB and thoracic paravertebral block TPVB, for pain relief after thoracoscopic radical resection of lung cancer. The main goal is to compare how these methods affect the amount of opioid pain medication needed after surgery. This study involves adult patients undergoing lung cancer surgery and aims to understand which nerve block provides better postoperative pain control. Participants are randomly assigned to one of two groups one receiving ultrasound-guided retro-SCTLB and the other receiving ultrasound-guided TPVB. Both procedures are performed 15 minutes before general anesthesia. During surgery, general anesthesia is maintained with specific medications and monitoring. After surgery, patients receive patient-controlled intravenous analgesia with sufentanil and tropisetron, with pain scores and opioid use closely monitored at several time points up to 48 hours. Throughout the study, nurses who do not know the group assignments evaluate pain scores at rest and during movement at 1, 3, 6, 12, 24, and 48 hours postoperatively. Researchers also track opioid dosage during and after surgery, adverse reactions, time to first walking after surgery, quality of recovery scores, and length of hospital stay up to 15 days. Safety and effectiveness of the nerve blocks are assessed by comparing these measures between the two groups.
