Secondary outcomes included extubation time, Quality of Recovery-40 (QoR-40) and Quality of Recovery-15 (QoR-15) scores, pain scores at 24 hours postoperatively, incidence of postoperative nausea and vomiting (PONV), postoperative sleep quality, anxiety and depression, and mental side effects. A comprehensive literature search was conducted in PubMed, EMBASE, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure from inception through April 20, 2023, with an update on May 18, 2024. The study was registered on PROSPERO (Registration number: CRD42023399290). Mean differences (MD) or relative risks (RR) with 95% confidence intervals (CI) were used to estimate effect sizes.
