A Review on Supplemental Oxygen Effects on Nausea and Vomiting in Patients under Spinal Anesthesia for Elective Cesarean

Introduction: Nausea and vomiting is seen after surgery in 20 to 70 percent of cases. In some studies supplemental oxygen could decrease Nausea and vomiting after surgery and in other studies it had no positive effect to decrease Nausea and vomiting. So this study aims to study on using supplemental oxygen effects on Nausea and vomiting changes of elective cesarean in patient under spinal anesthesia. Methods: 120 women who candidates for elective cesarean were chosen randomly for two-group intervention study. During the surgery and for six hours after surgery the intervention group received 60% oxygen and the control group received 30% oxygen with simple mask. The rate of Nausea and vomiting was recorded by visual tool (VAS) and the result was analyzed by SPSS19. Result: the incidence of Nausea and vomiting during surgery, recovery and women ward was different but there was not meaningful difference. There was also no meaningful difference for the intensity of Nausea and vomiting between two groups. Conclusion: in this study clinical trial to prescribe supplemental oxygen could not show any prevention role on Nausea and vomiting rather than routine oxygen.
