Abstract

ETHNOPHARMACOLOGICAL RELEVANCE: Ginger has been proposed for prevention of postoperative nausea and vomiting (PONV), however it remains equivocal whether ginger can be an alternative option and which certain preparation is optimal for PONV prophylaxis. AIM OF THE STUDY: We conducted a network meta-analysis (NMA) to compare and rank relative efficacy for PONV control among all available ginger preparations collected in the databases. METHODS: Eligible records were identified by retrieving Medline (via Pubmed), Embase, Web of Science, CENTRAL, CNKI, WHO ICTRP and ClinicalTrials.gov for randomized controlled trials that investigated the efficacy of ginger therapies for the prophylaxis of PONV. A bayesian NMA within random-effects models was implemented. Certainty of evidence for estimates was investigated following GRADE framework. We prospectively registered the protocol (CRD 42021246073) in PROSPERO. RESULTS: Eighteen publications comprising 2199 participants with PONV were identified. Ginger oil (RR [95%CI], 0.39 [0.16, 0.96]) appeared to have the highest probability of being ranked best to decrease the incidence of postoperative vomiting (POV), with statistical significance compared with placebo, based on high to moderate confidence in estimates. With regard to reducing postoperative nausea (PON), statistically superiority was not observed in ginger regimens compared with placebo based on moderate to low certainty of evidence. Reduction in antemetic use and nausea intensity were noticed in ginger powder and oil. Ginger was significantly associated with better efficacy for Asian, older age, higher dosage, preoperative administration, hepatobiliary and gastrointestinal surgery. CONCLUSIONS: Ginger oil appeared to be superior to other ginger treatments for the prophylaxis of POV. With regard to reducing PON, ginger preparations indicated no obvious advantages.
