Impact of a multimodal anti‐emetic prophylaxis on patient satisfaction in high‐risk patients for postoperative nausea and vomiting

179 surgical patients, comprising 108 high-risk patients for postoperative nausea and vomiting (PONV) (predicted risk 79-87%) and a random sample of 71 female patients with low or moderate risk.

Multimodal anti-emetic prophylaxis: total intravenous anaesthesia with propofol, high fractional inspired oxygen (80%), omission of nitrous oxide, dexamethasone 8 mg, haloperidol 10 microg.kg(-1), and tropisetron 2 mg.

Balanced propofol-desflurane anaesthesia without prophylactic anti-emetics (administered to the low/moderate risk control group).

Incidence of PONV and patient satisfaction measured using the willingness-to-pay method at 2 and 24 h after surgery.patient reported
