Assignment will be performed by opening a sequentially numbered opaque envelope containing computer-randomized individual allocations. The envelope will be opened by the circulation nurse in the operating room and silently viewed by the surgeons prior to surgery. Instructions will be given to not verbalize the treatment arm revealed. The original randomization will be performed by research staff before the initiation of the study using a random number table generator, and the participants will be blinded to treatment once assigned. Information regarding basic demographic data, interventions during the cesarean delivery and postpartum course will be obtained from the participant's charts after discharge from the hospital. The patients will be assessed for pain control, nausea and vomiting after cesarean section. The protocol for labor management and fetal monitoring will be the same for both groups, including continuous electronic fetal monitoring prior to delivery.
