Development of a multivariable predictive model for postoperative nausea and vomiting after cancer surgery in adults

Risk factors for post-caesarean nausea and vomiting: a prospective prognostic study

“…Before surgery, all patients were asked about motion sickness and smoking (if never smoked, if still smokes, if quit smoking less than 1 month, between 1 to 3 months, between 3 to 6 months, or more than 6 months before the surgery) because we have shown this discrimination can impact the expected probability of PONV. 6 We also asked about significant nausea during the first trimester and during the third trimester questioning, for example, “Did you experience significant nausea during the first trimester?”. We recorded Apfel simplified model’s score for each participant.…”
