In the present study, the effects of supplemental oxygen has been assessed on the incidence and severity of nausea and vomiting in the patients after cesarean surgery under spinal anesthesia Materials and Methods: This study was a randomized clinical trial and 122 women who were candidate for cesarean surgery were assigned randomly into intervention and control groups. Intervention group received 80 percent O2 equivalent to 12 liter per minute, continuously during surgery and after surgery in recovery room, and alternatively 6 hours by use of ventury mask in the ward. The control group received 30 percent O2, equivalent to 3-5 liters per minute with a regular mask as a routine measure. The incidence and severity of nausea and vomiting was recorded during surgery, up to 6 hours after surgery, in the recovery room and in the postpartum ward. Results: According to the results, the incidence of nausea during surgery showed no significant relationship but it showed a significant difference in the recovery room and at the postpartum ward in the intervention and control groups (p M3 ER -
