Authors' conclusion

Adding pre-operative oral olanzapine to intra-operative dexamethasone and ondansetron was highly effective in reducing the risk of postoperative nausea or vomiting in the first 24 hours after surgery in patients with a previous history of chemotherapy-induced nausea and vomiting and at least three Apfel risk factors for postoperative nausea or vomiting.
