Opioid-free anesthesia for minimally invasive abdominal surgery: a systematic review, meta-analysis, and trial sequential analysis.
Purpose: Opioid anesthesia is commonly employed in minimally invasive surgeries but is associated with adverse effects, including postoperative nausea and vomiting (PONV). Opioid-free anesthesia aims to mitigate these issues. We conducted a systematic review, meta-analysis, and trial sequential analysis (TSA) comparing opioid and opioid-free anesthesia in minimally invasive abdominal surgeries.
Methods: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase for randomized controlled trials (RCTs) comparing these approaches. Our primary outcomes were adverse effects (PONV, bradycardia), while secondary outcomes were pain, opioid consumption, and postanesthesia care unit (PACU) length of stay (LOS). We performed a TSA to investigate the conclusiveness of the results.
Results: We included 26 RCTs encompassing 2,025 patients, with 1,009 (49%) in the opioid-free anesthesia group. Opioid-free anesthesia reduced PONV significantly (risk ratio, 0.55; 95% confidence interval [CI], 0.40 to 0.74; P < 0.001), but we found no significant differences in bradycardia rates. We found nonclinically relevant higher pain scores for opioid anesthesia (mean difference [MD], -0.9; 95% CI, -1.7 to -0.2; P = 0.01) and opioid consumption at 2 hr post surgery (MD, -5.4 mg oral morphine equivalents; 95% CI, -9.1 to -1.8; P = 0.004). We also noted a reduced time to first analgesia (MD, 88 min; 95% CI, 18 to 159; P = 0.01). We found no differences in PACU LOS. The TSA confirmed the sample size's adequacy in showing PONV reduction with opioid-free anesthesia.
Conclusion: Opioid-free anesthesia showed a significant reduction in PONV and a decrease in opioid consumption during the first 2 hr postoperatively, suggesting it can be an alternative to opioid anesthesia in minimally invasive abdominal surgeries.

期刊介绍：
The Canadian Journal of Anesthesia (the Journal) is owned by the Canadian Anesthesiologists’
Society and is published by Springer Science + Business Media, LLM (New York). From the
first year of publication in 1954, the international exposure of the Journal has broadened
considerably, with articles now received from over 50 countries. The Journal is published
monthly, and has an impact Factor (mean journal citation frequency) of 2.127 (in 2012). Article
types consist of invited editorials, reports of original investigations (clinical and basic sciences
articles), case reports/case series, review articles, systematic reviews, accredited continuing
professional development (CPD) modules, and Letters to the Editor. The editorial content,
according to the mission statement, spans the fields of anesthesia, acute and chronic pain,
perioperative medicine and critical care. In addition, the Journal publishes practice guidelines
and standards articles relevant to clinicians. Articles are published either in English or in French,
according to the language of submission.
