    Eclampsia

    Eclampsia is seizures (convulsions) in a pregnant woman. These seizures are not related to an existing brain condition.

    Causes

    Doctors do not know exactly what causes eclampsia. The following may play a role:

    • Blood vessel problems
    • Brain and nervous system (neurological) factors
    • Diet
    • Genes

    Eclampsia follows a condition calledpreeclampsia. This is a serious complication of pregnancy that includes high blood pressure and excess and rapid weight gain.

    It is hard to predict which women with preeclampsia go on to have seizures. Women at high risk of seizures have severe preeclampsia and:

    • Abnormal blood tests
    • Headaches
    • Very high blood pressure
    • Vision changes

    Your chance ofgetting preeclampsia increases when:

    • You are35 or older
    • You areAfrican American
    • This is your first pregnancy
    • You havediabetes, high blood pressure, or kidney disease
    • You are having more than one baby (twins, triplets, etc.)
    • You are a teen

    Symptoms

    Symptoms of eclampsia include:

    • Muscle aches and pains
    • Seizures
    • Severe agitation
    • Unconsciousness

    Symptoms of preeclampsia include:

    • Gaining more than 2 pounds a week
    • Headaches
    • Nausea and vomiting
    • Stomach pain
    • Swelling of the hands and face
    • Vision problems

    Exams and Tests

    The health care provider will do a physical exam to check for possible causes of seizures. Blood pressure and breathing rate will be checked and monitored.

    Blood and urine tests may be done to check:

    • Blood clotting factors
    • Creatinine
    • Hematocrit
    • Uric acid
    • Liver function
    • Platelet count
    • Protein in the urine

    Treatment

    Delivering your babyis the main treatment for severe preeclampsia to prevent eclampsia.Allowing the pregnancy to go on can be dangerous to both you and the baby.

    You may be given medicine to prevent seizures.These medicines are called anticonvulsants.

    Your doctor may prescribe medicine to lower high blood pressure. If your blood pressurestays high, delivery may be needed, even if your baby is premature.

    Possible Complications

    Women with eclampsia or preeclampsia have a higher risk of:

    • Separation of the placenta (placenta abruptio)
    • Premature delivery that leads to complications in the baby
    • Blood clotting problem

    When to Contact a Medical Professional

    Call your health care provider or go to the emergency room if you have any symptoms of eclampsia or preeclampsia. Emergency symptoms include seizures or decreased alertness.

    Seek medical care right away if you have any of the following:

    • Bright red vaginal bleeding
    • Little or no movement in the baby
    • Severe headache
    • Severe pain in the upper rightabdominal pain
    • Vision loss
    • Nausea or vomiting.

    Prevention

    It is important for all pregnant women to get early and ongoing medical care. This allows for early diagnosis and treatment of conditions such as preeclampsia. Treating preeclampsia may prevent eclampsia.
