Many patients are more afraid of post-op nausea and vomiting (PONV) than they are of the surgery itself. That means a single incident of PONV can wreak havoc on your patient satisfaction scores and even prevent patients from scheduling critical surgeries in the future. Luckily, if you identify whether a patient is at a greater risk for this complication well before their procedure, you have plenty of options — including antiemetics, acupressure, aromatherapy and low-flow anesthesia — to prevent it.
