[PROSPECTIVE INVESTIGATION OF POSTOPERATIVE NAUSEA AND VOMITING FOLLOWING DUAL PROPHYLAXIS AND LOW DOSE NEURAXIAL MORPHINE FOR CESAREAN DELIVERY].

We report that almost 20% of the women managed with prophylactic dual therapy of ondansetron and dexamethasone had nausea during the 24 hours after administration of low dose intrathecal morphine. Our findings suggested that women who experience nausea or vomiting in the immediate postoperative period are at increased risk of nausea and vomiting in the 24-hour postoperative period.
