Postoperative Nausea and Vomiting

Intraoperative nausea and vomiting (IONV) and postoperative nausea and vomiting (PONV) are unpleasant peripartum experiences associated with significant stressors for the obstetric patient. It is imperative to identify risk factors for IONV/PONV, take measures to reduce these factors, and administer IONV/PONV prophylaxis. Patients in whom prophylaxis is not given, or has failed, should be considered for combination therapy.
