Postoperative pain is severe, and traditional opioids like sufentanil have side effects and may adversely affect tumor biology. Dezocine and nalbuphine are opioid agonist-antagonists with potentially better safety profiles. Their comparative effects on analgesia, complications, and flap survival in oral cancer surgery are unknown.\n\nObjective: To compare the efficacy of dezocine versus nalbuphine, both combined with sufentanil, for postoperative analgesia, and to evaluate their impact on postoperative complications and free flap survival\u002Ffunction in patients undergoing oral cancer radical surgery with flap reconstruction.\n\nMethods: This is a prospective, randomized, double-blind, controlled trial. Sixty eligible patients (aged 18-70, ASA I-III) will be randomly assigned (1:1) to receive postoperative patient-controlled intravenous analgesia (PCIA) with either Sufentanil + Dezocine or Sufentanil + Nalbuphine. The primary outcome is pain intensity assessed by the Visual Analogue Scale (VAS) at 2, 24, and 48 hours postoperatively. Secondary outcomes include flap survival status, sensory function recovery, incidence of adverse events (e.g., nausea, vomiting), and hospitalization duration.\n\nPotential Impact: This study may identify a superior postoperative analgesic regimen that provides effective pain relief while potentially improving flap outcomes and minimizing side effects for oral cancer patients.",[61,62,28,63],"Oral Cancer","Postoperative Pain Management","Mouth Neoplasms",[65,66,67,68,69,70,71],"Dezocine","Nalbuphine","Oral Cancer Surgery","Free Flap Reconstruction","Postoperative Analgesia","Randomized Controlled Trial","Flap Survival","RECRUITING","2026-02-03",{"date":75,"type":39},"2026-02-10",{"date":77,"type":39},"2025-06-01",{"date":79,"type":21},"2026-06-01",{"name":81,"class":46},"Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University"]
