What type of surgeries are associated with a higher risk of PONV?

Laparoscopic surgeries
Orthopedic surgeries
Plastic surgeries
Cardiac surgeries

The correct answer is: Laparoscopic surgeries

Laparoscopic surgeries are associated with a higher risk of postoperative nausea and vomiting (PONV) due to several factors inherent to these procedures. The use of carbon dioxide insufflation to create a pneumoperitoneum during laparoscopic procedures can increase intra-abdominal pressure and stimulate visceral stretch receptors, leading to an increased likelihood of nausea. Additionally, the length of time spent under anesthesia and the use of certain anesthetic agents, which are common in laparoscopic surgeries, further contribute to the risk of PONV. While other types of surgeries listed may also have considerations for PONV, they typically do not present the same combination of factors that significantly elevate the risk as seen in laparoscopic surgeries. Certain demographic factors, such as being a female patient or having a history of motion sickness, can also exacerbate the risk during laparoscopic procedures. Thus, the characteristics and techniques used in laparoscopic surgeries are key contributors to the heightened risk of PONV seen in these cases.
