Planned to receive liposomal bupivacaine regional block analgesia under direct thoracoscopic visualization.\n3. Body mass index (BMI) 18-30 kg\u002Fm².\n4. Willing and able to cooperate with the study procedures and provide written informed consent.\n\nExclusion Criteria:\n\n1. Regularly taking beta-blockers (for ≥2 weeks) or long-term use of high-dose glucocorticoids (prednisone ≥20 mg\u002Fday for \\>2 weeks).\n2. Known history of diabetes mellitus, or regular use of glucose-lowering agents (oral agents or insulin) before surgery.\n3. Planned postoperative admission to the intensive care unit (ICU).\n4. Concurrent severe cardiac (New York Heart Association class III or higher), hepatic (e.g., cirrhosis), or renal insufficiency (glomerular filtration rate \\\u003C30 mL\u002Fmin\u002F1.73 m²), or neuropsychiatric disorders.\n5. Contraindications to regional block or to any study medication, including but not limited to infection or tumor invasion at the puncture site, coagulation disorders, or allergy to any drug used in the study.\n6. Alcohol dependence: meeting the DSM-5 criteria for severe alcohol use disorder (AUD), or clinically judged as alcohol dependence (regardless of liver function status).\n7. Pregnancy or lactation (for men and women of childbearing potential, effective contraception is required until 3 months after surgery, and donation of sperm or eggs is prohibited).\n8. Participation in another interventional drug trial.\n9. Regular use of analgesics for acute or chronic pain within 2 weeks before surgery.\n10. Concurrent severe infection.\n11. Prior ipsilateral intrathoracic surgery or severe pleural adhesions (estimated to preclude successful thoracoscopic visualization and completion of the block).\n12. Psychiatric or cognitive disorders that would impair the ability to cooperate with postoperative follow-up.\n13.
