The antiemetic efficacy and safety of prophylactic metoclopramide for elective cesarean delivery during spinal anesthesia.
OBJECTIVE
The efficacy and safety of intravenous metoclopramide administered prophylactically before elective cesarean delivery under spinal anesthesia was studied.


METHODS
In a double-blind, randomized fashion, 42 ASA Physical Status I-II parturients at term were assigned to receive either 10-mg intravenous metoclopramide or an equal volume of normal saline before induction of spinal anesthesia. The occurrence of nausea and/or vomiting recorded throughout the perioperative period until the patient was admitted to the recovery room. Neonatal acid-base status and neurobehavioral exams were obtained.


RESULTS
Patients in the group receiving metoclopramide had a significantly lower incidence of nausea and vomiting both before and after delivery than the control group (14% versus 81% overall). All neonatal acid-base values were within normal limits and there were no significant differences in neurobehavioral exam results between the two groups.


CONCLUSIONS
Metoclopramide administered before induction of spinal anesthesia for cesarean delivery appears to significantly reduce both pre- and postdelivery emetic symptoms without apparent adverse effects on mother or neonate.
