Why is preeclampsia called preeclampsia?

Preeclampsia is so named because it was originally identified as a disorder preceding eclampsia, although it is now known that eclamptic seizures are only one of the several potential complications of the disease. Eclamptic seizures usually occur as a later complication of severe preeclampsia, but may also arise without any prior signs of severe disease.

How to manage preeclampsia?

Many factors guide a healthcare provider’s decision about how to manage preeclampsia, including the gestational age and health of the baby, overall health and age of the mother, and a careful assessment of how the disease is progressing. This includes monitoring blood pressure and assessing the results of laboratory tests that indicate the condition of the mother’s kidneys, liver, or the ability of her blood to clot. Other tests monitor how well the unborn baby is growing and/or if he or she seems in danger. When the pregnancy is less than 37 weeks the caregiver usually tries to gain some time, but if 37 weeks or later, the provider will often opt to deliver the baby.

Preeclampsia is often diagnosed during routine prenatal appointments, when your healthcare provider checks your weight gain, blood pressure and urine protein. If preeclampsia is suspected, additional blood tests may be ordered.

An ultrasound and fetal monitoring may also be used to provide more information about the baby.

How to treat preeclampsia?

Your healthcare provider will advise you on the best way to treat preeclampsia. Preeclampsia can only be cured with delivery. If you're at term (37 weeks gestational age or greater), the baby will be delivered.

If the preeclampsia worsens or becomes more severe, the baby will be delivered. Women with preeclampsia can have a vaginal delivery through induction of labor — which is more likely to be successful if you're closer to term — or planned cesarean section. During labor and following delivery, women with preeclampsia are often given magnesium intravenously (directly into the vein) to prevent development of eclampsia.

During normal pregnancy, the villous cytotrophoblast invades into the inner third of the myometrium, and spiral arteries lose their endothelium and most of their muscle fibers. These structural modifications are associated with functional alterations, such that spiral arteries become low-resistance vessels, and thus less sensitive, or even insensitive, to vasoconstrictive substances.
