Effect of thoracic paravertebral block with ropivacaine and compound betamethasone on postoperative pain after thoracoscopic surgery: A randomized, double-blind, controlled trial

These results suggest that the combination of ropivacaine and compound betamethasone in TPVB effectively reduces both acute and chronic postoperative pain after thoracoscopic surgery. It also decreases the incidence of postoperative adverse reactions, making it a superior adjuvant for TPVB with local anesthetics.
