    Postoperative nausea and vomiting (PONV) has a significant impact on patients and health care providers. Some nonpharmacologic methods may have an effect on PONV. Administration of supplemental oxygen (80%) during and for 2 hours after surgery has been shown to reduce the incidence of PONV from 44% to 22%. However, the effect of limiting supplemental oxygen to the immediate postoperative period on PONV is unknown. The purpose of this study was to test the efficacy of postoperative supplemental oxygen in reducing the incidence of PONV. Patients (n = 106) undergoing cesarean birth were given general anesthesia with 50% oxygen balanced nitrous oxide and in the postoperative period were randomly assigned to 2 groups. Patients in the experimental group received 8 L/min oxygen by a simple face mask for 6 hours. The control group received routine care of oxygen 5 L/min in the PACU and no supplemental oxygen on the ward. Trained nurses evaluated pulse oximetry and PONV after surgery. The incidence of PONV during the first 6 postoperative hours was 28.3% in the experimental group and 24.5% in the control group ( P = .659). There was no statistically significant difference between the 2 groups. In this study, postoperative supplemental oxygen 8 L/min did not prevent PONV in patients undergoing cesarean birth.
