Abstract: Background: It is reported that postoperative nausea and vomiting, common general anesthesia complications, may be prevented by perioperative intravenous dextrose administration, but with controversial clinical effectiveness. Objective: To evaluate perioperative intravenous dextrose for preventing postoperative nausea and vomiting through a systematic review and meta-analysis of randomized controlled trials with trial sequential analysis. Data sources: MEDLINE, the Cochrane Central Register of Controlled Trials, Embase, Web of Science, clinicaltrials.gov, and the University Hospital Medical Information Network Clinical Trials Registry were searched from inception until 22 June 2019. Eligibility criteria: Trials investigating intravenous dextrose effects vs. placebos on postoperative nausea and vomiting in patients who underwent general anesthesia. Results: Eleven trials (1,250 patients) were included. All participants were ASA1-2. The nine trials included laparoscopic surgeries, and 92.2% of the participants were women. The timing of dextrose infusion was before, during, and after surgery in three, five, and three trials, respectively. Our results revealed intravenous dextrose administration significantly reduced postoperative nausea, but not vomiting, during early and late postoperative periods (risk ratio [95% confidence interval], early nausea: 0.76 [0.59–0.99], late nausea: 0.65 [0.48–0.89]; early vomiting: 1.00 [0.81–1.25], late vomiting: 0.96 [0.43–2.16]). Evidence quality was downgraded to low because the trial sequential analysis indicated more trials are needed for firm conclusions. Conclusions: Compared with placebos, perioperative intravenous dextrose administration may decrease postoperative nausea but not vomiting. Trial registration: University Hospital Medical Information Network Clinical Trials Registry (registration number: UMIN000030901).
