Postoperative nausea and vomiting: which plan constitutes basic multimodal prophylaxis?

• A. Administer antiemetics from different classes and minimize volatile agents and opioids
• B. Use antiemetics from a single class
• C. Hydration status only
• D. Avoid antiemetics altogether

Answer: (A)

Postoperative nausea and vomiting is driven by multiple pathways, so preventing it works best when you attack several receptors at once and reduce the factors that trigger symptoms. Administering antiemetics from different drug classes covers more mechanisms of action, which reduces the likelihood of emesis more effectively than a single-agent approach. At the same time, minimizing exposure to volatile agents and opioids lowers the stimuli that can provoke nausea and vomiting after surgery. Together, these elements form a basic multimodal prophylaxis strategy: combine antiemetics from distinct pharmacologic classes and reduce emetogenic triggers. Using only one class misses other pathways, hydration alone doesn’t address the pharmacologic drivers, and avoiding antiemetics altogether leaves the patient unprotected.
