Review Meta Analysis Comparative Study
[Prophylaxis of nausea and vomiting in the postoperative phase: relative effectiveness of droperidol and metoclopramide].
The aim of the present study was to conduct a meta-analysis of the results from randomized controlled trials investigating the relative efficacy of droperidol versus metoclopramide for the prevention of postoperative nausea and vomiting (PONV). ⋯ For the prevention of postoperative nausea and vomiting droperidol is significantly superior to metoclopramide doses below 20 mg. There was no obvious positive dose response with respect to increasing doses of metoclopramide. There was also a trend towards higher efficacy of droperidol compared to higher doses of metoclopramide (≥20 mg). However, there were not enough comparative studies to show a statistically significant result in this subgroup analysis. These data support the notion that droperidol in low doses may represent the more effective D(2)-antagonist for a pharmacological armamentarium to cope with PONV.
