Abstrakt: Study Objective: Opioid-free anaesthesia may enhance postoperative recovery by reducing opioid-related side effects such as nausea, hyperalgesia or tolerance. The objective was to investigate the impact of multimodal opioid-free general anaesthesia on postoperative nausea, vomiting, pain and morphine consumption compared to the traditional opioid-based approach.
Design: This study was conducted as a prospective parallel-group randomised controlled trial.
Setting: Perioperative Care.
Patients: 152 adult women undergoing elective inpatient gynaecological laparoscopy.
Interventions: Patients were randomly assigned for opioid-free anaesthesia (Group OF) with dexmedetomidine, esketamine and sevoflurane or to have opioid-based anaesthesia (Group C) with sufentanil and sevoflurane.
Measurements: Primary outcome was the occurrence of nausea within 24 h after surgery. Patients were assessed for the incidence and severity of PONV, postoperative pain and morphine consumption and recovery characteristics.
Main Results: Patients in both groups had comparable clinical and surgical data. 69.7% of patients in the control group and 68.4% of patients in the opioid-free group met the primary endpoint (OR 1.06, 95% Confidence Interval (CI) (0.53; 2.12) p = 0.86). The incidence of clinically important PONV defined by the PONV impact scale was 8.1% (Group C) vs 10.5% (OF); p = 0.57). Antiemetic requirements, pain scores and morphine consumption were equivalent in both groups. Postoperative sedation was significantly increased in group OF (p < 0.001), and the median length of stay at the post-anaesthesia care unit was 69.0 min (46.5-113.0) vs 50.0 (35.3-77.0) minutes in the control group (p < 0.001).
Conclusions: Opioid-free multimodal general anaesthesia is feasible but did not decrease the incidence of PONV, or reduce pain scores and morphine consumption compared to an opioid-containing anaesthetic regimen.
