An expectant mother may experience high blood pressure (preeclampsia), which increases the risk of preterm delivery and other potential dangers for the baby.
The most common symptom of eclampsia is seizures or convulsions. Similar to preeclampsia, other changes and symptoms may be present and vary according to the organ system or systems that are involved. These changes can affect the mother, the baby, or more commonly both mother and baby together. Some of these following symptoms may be perceived by the pregnant woman, but, more commonly, she is unaware that she has this disease:
If any of the previously mentioned symptoms are experienced, a health-care professional should be notified immediately. If home blood pressure monitoring is being performed, the readings, if elevated, should be reported to the doctor. It is likely that a visit to the doctor's office or the hospital may be necessary.
Once eclampsia develops, the only treatment is delivery of the baby (if eclampsia occurs prior to delivery). Eclampsia can develop following delivery, typically within the first 24 hours postpartum. Rarely, the onset of post-partum eclampsia can be delayed and occur up to one week following delivery. There is no cure for eclampsia other than the delivery of the infant. Seizure treatment
Once the mother's condition is stabilized following a seizure, the physician will prepare for emergent delivery of the infant. This can occur by either cesarean section or induction of labor and vaginal delivery. If the patient is already in labor, labor can be allowed to progress provided there is no evidence that the baby has become "distressed " or compromised by the seizure. High blood pressure medication
Medication to deliver the babyThe closer the patient is to her due date, the more likely her cervix will be favorable for delivery, and that induction of labor will be successful. Sometimes medications, such as oxytocin (Pitocin), are given to induce or shorten labor.
Most women will have good outcomes for their pregnancies, even when complicated by preeclampsia or eclampsia. Some women will continue to have problems with their blood pressure and will need to be followed closely after delivery. About 25% of women who have had eclampsia will have elevated blood pressure in a subsequent pregnancy, and about 2% will develop eclampsia. Most babies do well. Babies born prematurely will usually stay in the hospital longer. A rule of thumb is to expect the baby to stay in the hospital until their due date. Unfortunately, a few women and babies experience life-threatening complications from preeclampsia or eclampsia. Complications in babies are generally related to prematurity, and outcomes for both mothers and babies are significantly worse in developing countries. The maternal mortality (death) rate from eclampsia in developed counties ranges from 0% to 1.8% of cases. Most of the cases of maternal death are complicated by a condition known as HELLP syndrome, which is characterized by hypertension, hemolytic anemia, elevated liver function tests (LFTs), and a low platelet count. Just as there were no tests to predict or prevent eclampsia, there are no tests to predict whether preeclampsia or eclampsia will recur in a subsequent pregnancy. Unfortunately, in a small number of women, preeclampsia and/or eclampsia will recur. This change seems to increase if the preeclampsia or eclampsia was particularly severe in the previous pregnancy, occurred very early in that pregnancy (late second trimester or early third trimester), or there is a new father for the subsequent pregnancy. Because there are no tests to predict recurrent preeclampsia/eclampsia, a previously affected patient should be followed more closely during a subsequent pregnancy. See Slideshow
The various changes and symptoms that occur with preeclampsia vary according to the organ system or systems that are affected. These changes can affect the mother only, baby only, or more commonly affect both mother and baby. Some of these symptoms give the woman warning signs, but most do not. When they do the woman may experience:
