Magnesium sulphate is the first line therapy for the management of preeclampsia and eclampsia in obstetrics. Perioperative administration of magnesium sulphate has been proved to be an effective as an analgesic adjuvant. The investigators evaluated the analgesic effect of magnesium in parturients undergoing Cesarean section.
