Randomized Controlled Trial Clinical TrialEffect of postoperative supplemental oxygen on nausea and vomiting after cesarean birth.
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%. ⋯ 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.
