Eclampsia is the onset of seizures (convulsions) in a woman with pre-eclampsia. [1] Pre-eclampsia is a hypertensive disorder of pregnancy that presents with three main features: new onset of high blood pressure, large amounts of protein in the urine or other organ dysfunction, and edema.
Pre-eclampsia affects 2–8% of pregnancies worldwide. [4] [17] [12] Hypertensive disorders of pregnancy (which include pre-eclampsia) are one of the most common causes of death due to pregnancy. [6] They resulted in 46,900 deaths in 2015. [7] Pre-eclampsia usually occurs after 32 weeks; however, if it occurs earlier it is associated with worse ...
Magnesium sulfate is effective in decreasing the risk that pre-eclampsia progresses to eclampsia. [24] Intravenous magnesium sulfate is used to prevent and treat seizures of eclampsia. It reduces the systolic blood pressure but does not alter the diastolic blood pressure, so the blood perfusion to the fetus is not compromised.
Magnesium sulfate acts as a vasodilator, reducing vascular resistance and protect the blood-brain barrier (BBB). The goal of these treatments is to prolong pregnancy and increase fetal survival. Each day gained by treatment in utero increases fetal survival and intact survival by 1%–2% up to 28 weeks gestation. [35]
It was a sign of preeclampsia, which doctors dismissed. When Lindsay Orr, then 32, was 30 weeks pregnant, she started seeing stars in her vision. It was a sign of preeclampsia, which doctors ...
Severe pre-eclampsia involves a BP over 160/110 (with additional signs). It affects 5–8% of pregnancies. [20] Eclampsia – seizures in a pre-eclamptic patient, affect around 1.4% of pregnancies. [21] Gestational hypertension can develop after 20 weeks but has no other symptoms, and later rights itself, but it can develop into pre-eclampsia. [22]
This is particularly true if the pregnancy is beyond 34 weeks of gestation. [2] Medications may be used to decrease blood pressure and blood transfusions may be required. [1] HELLP syndrome occurs in about 0.7% of pregnancies and affects about 15% of women with eclampsia or severe pre-eclampsia. [5] [2] Death of the mother is uncommon (< 1%).
Chronic kidney disease, excretion of magnesium becomes impaired when creatinine clearance falls below 30 ml/min. However, hypermagnesemia is not a prominent feature of chronic kidney disease unless magnesium intake is increased.
