Nursing
Summary
Preeclampsia is new-onset hypertension after weeks of pregnancy accompanied by proteinuria or qualifying maternal organ dysfunction. Eclampsia involves new-onset seizures associated with preeclampsia that are not explained by another cause. Either condition may first appear postpartum.
| Condition | Distinguishing findings | Management emphasis |
|---|---|---|
| Preeclampsia | Hypertension with proteinuria or qualifying organ dysfunction | Assess severe features; administer magnesium sulfate for seizure prophylaxis when severe features are present |
| Eclampsia | Seizures associated with preeclampsia | Immediately stabilize the mother and administer magnesium sulfate |
Hypertension is systolic pressure or diastolic pressure on two readings at least hours apart. Severe-range hypertension is systolic pressure or diastolic pressure ; prompt confirmation permits urgent treatment. Proteinuria is urine protein per hours or a protein-to-creatinine ratio .

Differentiating Preeclampsia and Eclampsia in Maternal Care
📘 Overview Preeclampsia is new-onset hypertension after weeks of pregnancy with proteinuria or qualifying maternal organ dysfunction. Eclampsia is new-onset seizure activity associated with preeclampsia and not explained by another cause. Both conditions can first appear postpartum.
🧠 Key Idea Seizures distinguish eclampsia from preeclampsia; proteinuria is not required when qualifying organ dysfunction is present. Eclampsia requires immediate maternal stabilization and magnesium sulfate, while severe hypertension requires separate antihypertensive treatment.
⚔️ Core Details: - Severe features include severe-range blood pressure, thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, or persistent neurologic symptoms. - Immediate seizure care prioritizes side-lying positioning, protection from injury, and airway support without restraints or objects placed in the mouth. - Magnesium sulfate is first-line therapy for eclamptic seizures and seizure prophylaxis in preeclampsia with severe features. - Magnesium sulfate monitoring includes respiratory rate, deep tendon reflexes, and urine output. - Persistent acute severe hypertension requires urgent treatment with prescribed intravenous labetalol, intravenous hydralazine, or immediate-release oral nifedipine. - Delivery after maternal stabilization is definitive obstetric management; timing depends on maternal status, fetal status, and gestational age.
🎯 Why It Matters: - Early recognition of severe features can prevent progression to seizures, stroke, pulmonary edema, and maternal death. - Placental dysfunction can compromise fetal growth and oxygenation, making fetal surveillance essential. - Postpartum vigilance is necessary because delivery does not immediately eliminate the risk of seizures or severe hypertension. - Eclampsia alone does not mandate cesarean birth; the route of delivery depends on obstetric circumstances.
