Reexamining Metoclopramide's Role in the Prevention of Postoperative Nausea and Vomiting: A Secondary Analysis.

Postoperative nausea and vomiting (PONV) continue to be among the most undesirable and distressing complications following general anesthesia, affecting 20% to 30% of all surgical patients and up to 70% of patients with multiple known risk factors. The purpose of this study was to reexamine the effectiveness of metoclopramide in the prevention of PONV when stratified by PONV risk scores. Secondary data from 2,116 adult ambulatory surgical patients were analyzed.
