BACKGROUND: Different categories of drugs are used to reduce the incidence of post-operative nausea and vomiting (PONV) following laparoscopic cholecystectomy (LC). This study is a network meta-analysis of randomized clinical trials with such drugs.
METHODS: Electronic databases were searched for appropriate randomized clinical trials evaluating drugs reducing PONV in LC. Number of patients without PONV at 24 h was the primary outcome; and incidence of nausea and/or vomiting at 6 h and 24 h, and adverse events were the secondary outcome measures. Risk of bias was evaluated for each study. Mixed treatment comparison estimates were derived by random-effects modelling. Trial sequential analysis was carried out to assess the adequacy of evidence; and surface area under cumulative ranking curve was generated to identify the best intervention in the pool. Grading of the evidence for key comparisons was done.
RESULTS: Ninety clinical trials were included. Metoclopramide, gabapentin, dixyrazine, ondansetron, granisetron, dexamethasone, tropisetron, droperidol, droperidol/dexamethasone, droperidol/metoclopramide, granisetron/droperidol and granisetron/dexamethasone, haloperidol, dexmedetomidine, palonosetron, droperidol/ondansetron, metoclopramide/dexamethasone, haloperidol/ondansetron, haloperidol/dexamethasone, palonosetron/dexamethasone and ramosetron/dexamethasone were observed with significant benefits compared to placebo. Corticosteroid/serotonin receptor antagonists was observed with the highest probability of being the 'best' in this pool. However, the moderate quality of evidence obtained was adequate to confirm the benefits of dexamethasone and ondansetron only.
CONCLUSION: The relative effect sizes for various prophylactic anti-emetics for LC was modelled using the principles of network meta-analysis. Dexamethasone and ondansetron have the best evidence as stand-alone options and the combination is preferred in high-risk category. Caution should be exercised while interpreting the evidence as the estimates might change with head-to-head clinical trial data.
