What is the recommended number of MM agents for more than 2 PONV risk factors?

One
Two
Three
Four

The correct answer is: Three

When addressing the management of postoperative nausea and vomiting (PONV), it's essential to consider the risk factors present in each individual patient. The presence of more than two risk factors for PONV significantly raises a patient's likelihood of experiencing these symptoms after surgery. In such cases, utilizing multimodal therapy becomes critical to effectively minimize the incidence of PONV. The current guidelines suggest that if a patient presents with more than two risk factors, employing at least three different antiemetic agents can maximize the prophylactic effect. This approach capitalizes on the different mechanisms of action of each agent, which helps to provide comprehensive coverage against PONV. By recommending multiple agents, you cater to the varied pathways that can lead to nausea and vomiting, thereby enhancing patient outcomes and overall satisfaction with the surgical experience. Thus, the choice of using three agents aligns with best practices targeted toward patients at higher risk for PONV.
