What is a primary strategy to prevent postoperative nausea and vomiting (PONV) in the ambulatory surgery center setting?

• A. Perioperative antiemetic prophylaxis and optimizing anesthesia technique
• B. Early ambulation after surgery
• C. Reducing fluid administration
• D. Limiting surgical time

Answer: (A)

The main idea is preemptive antiemetic prophylaxis combined with anesthesia choices that minimize nausea triggers. In ambulatory surgery, preventing PONV starts before symptoms appear by giving antiemetics ahead of emergence and selecting techniques that reduce emetogenic exposure. A multimodal approach is most effective: using a combination such as a serotonin antagonist with dexamethasone, and adding additional agents like an NK1 receptor antagonist or a scopolamine patch for higher-risk patients. Pair this with anesthesia management that lowers PONV risk—propofol-based anesthesia, avoidance of volatile agents and nitrous oxide, and strategies that lessen opioid use (such as regional anesthesia or nonopioid analgesia). Together, these measures address the multifactorial causes of PONV and help achieve quicker, smoother recovery in the ambulatory setting. Early ambulation, while beneficial for overall recovery, does not primarily prevent PONV; fluids and surgical duration play roles but are not the principal preventive strategy.
