The purpose of this study is to better understand how much energy (calories) these patients need before and after surgery and whether nutrition is related to recovery, complications, and overall outcomes.\n\nWho can participate?\n\nAdults (18 years and older) with head and neck cancer who are scheduled to undergo free flap reconstructive surgery at Tel Aviv Sourasky Medical Center may be invited to participate.\n\nWhat will participants do?\n\nParticipants will undergo several nutrition-related assessments before and after surgery, including:\n\nIndirect calorimetry tests, which measure how much energy the body uses. Body composition measurements using a non-invasive device. A questionnaire about food intake. Collection of routine clinical information, laboratory results, and recovery data from medical records.\n\nThe indirect calorimetry assessments will be performed before surgery, several days after surgery, before hospital discharge, and approximately one month after discharge.\n\nWhat are the possible benefits of the study?\n\nThe information obtained may help researchers better understand the nutritional needs of patients with head and neck cancer undergoing major surgery. This knowledge may improve nutritional care and recovery for future patients.\n\nWill participation affect medical care?\n\nParticipation in the study will not change the standard medical or nutritional care patients receive. Nutritional follow-up will continue according to routine clinical practice.\n\nHow will privacy be protected?\n\nStudy data will be stored in a coded form, and access will be limited to authorized study personnel.

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.",[88,89,28,90],"Oral Cancer","Postoperative Pain Management","Mouth Neoplasms",[92,93,94,95,96,97,98],"Dezocine","Nalbuphine","Oral Cancer Surgery","Free Flap Reconstruction","Postoperative Analgesia","Randomized Controlled Trial","Flap Survival","2026-02-03",{"date":101,"type":35},"2026-02-10",{"date":103,"type":35},"2025-06-01",{"date":105,"type":21},"2026-06-01",{"name":107,"class":75},"Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University"]
