While modified opioid-sparing anaesthesia (MOSA) has been shown to lower the occurrence of adverse events related to OBA and OFA. This study is to assess the efficacy of MOSA in enhancing the recovery quality among individuals undergoing LBS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>A single-centre, prospective, double-blind, randomised controlled trial is conducted at a tertiary hospital. A total of 74 eligible participants undergoing elective LBS will be recruited and randomly allocated. Patients in the MOSA group will receive a combination of low-dose opioids, minimal dexmedetomidine, esketamine and lidocaine, while in the OBA group will receive standard general anaesthesia with opioids. Patients in both groups will receive standard perioperative care. The primary outcome is the quality of recovery-15 score assessed at 24\u2009hours after surgery. Secondary outcomes include pain levels, anxiety and depression assessments, gastrointestinal function recovery, perioperative complication rates, opioid consumption and length of hospital stay.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>Ethical approval has been provided by the Ethical Committee of Yan\u2019an Hospital of Kunming City (approval No. 2023-240-01).
