Detaillierte Beschreibung
This prospective randomised controlled study aims to evaluate the effects of opioid-free anaesthesia (OFA) compared with conventional opioid-based anaesthesia (OBA) in adult patients undergoing elective surgery under general anaesthesia. Eligible patients will be randomly assigned into two equal groups. The OFA group will receive a multi modal opioid-free anaesthetic regimen consisting of dexmedetomidine, ketamine, and lidocaine administered as loading doses followed by continuous infusions. The OBA group will receive fentanyl-based anaesthesia according to a standardised protocol. Both groups will receive similar induction agents, muscle relaxants, anti emetic prophylaxis, and postoperative analgesic regimens.
Preoperative hemodynamic parameters, including heart rate and blood pressure, will be recorded intraoperatively and during the postoperative period. Postoperative recovery will be assessed using the SAMPE recovery room discharge checklist(Stability, Awake and Oriented, Motor, Pain, and Emesis) recovery room discharge checklist, an eight-item score assessing vital signs stability, level of consciousness, spontaneous ventilation, oxygen saturation, pain control, absence of nausea and vomiting, absence of bleeding, and absence of motor block. Patients will be discharged from the post-anaesthesia care unit (PACU) upon achieving a SAMPE score of 8.. Pain intensity will be evaluated using the Visual Analogue Scale (VAS) at predetermined postoperative time points (0, 1, 6, and 12 hours). The incidence and severity of postoperative nausea and vomiting (PONV) during the first 24 postoperative hours will be recorded and graded using a standardised PONV severity score. Additional outcomes include time to first rescue analgesia, total postoperative opioid consumption, and the occurrence of opioid-related adverse events such as postoperative hypoxemia.
Furthermore, serum interleukin-6 (IL-6) levels will be measured preoperative, immediately after skin incision, and at 6 and 12 hours after induction of anaesthesia as a biomarker of the surgical stress response. The study seeks to determine whether opioid-free anaesthesia can improve postoperative recovery, reduce PONV and opioid requirements, and attenuate the preoperative stress response compared with conventional opioid-based anaesthesia.

Aktiver Komparator: Opioid-Based Anaesthesia (OBA)
Participants will receive conventional fentanyl-based anaesthesia during surgery in addition to standardized general anaesthesia.
|
Fentanyl will be administered intravenously as the opioid component of balanced general anaesthesia. Loading dose of 2 mic/kg I.V. followed by continuous infusion of three syringes, one with fentanyl infusion 0.5mic/kg/hr, and two syringes with normal saline. will receive IV acetaminophen (1 g) and ketrolac 30mg 10 minutes before incision closure. Postoperative Analgesia: All patients will receive IV acetaminophen 1 g /8h, ketrolac 30 mg/8h and rescue doses of pethideine 0.5 mg/kg IM if VAS score is ≥ 4. |
|
Aktiver Komparator: Opioid-Free Anaesthesia (OFA) Group
Participants will receive opioid-free anaesthesia consisting of dexmedetomidine, ketamine, and lidocaine administered as loading doses followed by continuous intravenous infusions during surgery, in addition to standardized general anaesthesia.
|
Dexmedetomidine: Loading dose of 1 µg/kg IV over 10 min before induction, followed by continuous infusion at 0.4 µg/kg/h . Ketamine: Loading dose of 0.25mg/kg followed by continuous infusion of ketamine at 0.1mg/kg/hr . Lidocaine: loading dose of 1.5mg/kg/hr followed by maintainance of 1mg/kg/hr. All three infusions to be stopped 30 minutes before skin closure will receive IV acetaminophen (1 g) and ketrolac 30mg 10 minutes before incision closure. Postoperative Analgesia: All patients will receive IV acetaminophen 1 g /8h, ketrolac 30 mg/8h and rescue doses of pethideine 0.5 mg/kg IM if VAS score is ≥ 4. |
