If preeclampsia occurs before the lungs of the fetus mature, the pregnant mother is typically given some magnesium sulfate to decrease the chance of seizures, which occur when preeclampsia becomes eclampsia—convulsions that can deprive the mother and baby of oxygen. Often the best way to deal with preeclampsia is to deliver the baby. If the pregnancy is not yet full term, obstetricians give another medication to boost fetal lung development so the prematurely delivered baby is less likely to suffer respiratory distress.
