Preeclampsia Severe Features

After 20 weeks' gestation, diagnose preeclampsia when new hypertension is present on two measurements at least 4 hours apart—systolic blood pressure at least 140 mm Hg or diastolic blood pressure at least 90 mm Hg—with proteinuria or qualifying maternal organ dysfunction. Severe-range blood pressure, defined as systolic at least 160 mm Hg or diastolic at least 110 mm Hg, may be confirmed over minutes rather than 4 hours to permit urgent treatment. jacc+2jaccPreeclampsia—Pathophysiology and Clinical Presentations: JACC State-of-the-Art ReviewNatureBiomarkers and point of care screening approaches for the management of preeclampsia | Communications MedicineajogPostpartum preeclampsia or eclampsia: defining its place and ...

Preeclampsia with severe features is present with any of the following: platelets below 100,000/mm3; serum creatinine above 1.1 mg/dL or doubling of baseline without another renal explanation; transaminases at least twice the laboratory upper limit of normal; persistent right-upper-quadrant or epigastric pain not explained by another diagnosis; pulmonary edema; or new headache unresponsive to medication without an alternative diagnosis, visual symptoms, or visual disturbance. jacc+2jaccPreeclampsia—Pathophysiology and Clinical Presentations: JACC State-of-the-Art ReviewajogPostpartum preeclampsia or eclampsia: defining its place and ...ACCOnline Exclusive | From the Member Sections | Optimizing Care of Patients with Hypertensive Disorders of Pregnancy: Putting an Enterprise Plan into Action - American College of Cardiology

Do not use the amount of proteinuria to downstage a patient with severe blood pressure or end-organ involvement. Establish proteinuria, when needed, with a 24-hour urine protein of at least 300 mg, urine protein-to-creatinine ratio at least 0.3, or dipstick 2+ only if quantitative testing is unavailable. jacc+1jaccPreeclampsia—Pathophysiology and Clinical Presentations: JACC State-of-the-Art ReviewNatureBiomarkers and point of care screening approaches for the management of preeclampsia | Communications Medicine

Admit patients with preeclampsia and severe features to labor and delivery or an equivalent inpatient setting for close maternal and fetal surveillance. Obtain a complete blood count, comprehensive metabolic panel, and urine protein-to-creatinine ratio; repeat assessment according to clinical trajectory to detect worsening thrombocytopenia, hepatic injury, or renal dysfunction.

For sustained severe hypertension, initiate a rapid-acting antihypertensive within 30 to 60 minutes. The urgent treatment target is prevention of maternal cerebrovascular and other severe complications rather than prolongation of pregnancy; severe hypertension itself may establish postpartum preeclampsia after other causes are excluded. ajogajogPostpartum preeclampsia or eclampsia: defining its place and ...

Use intravenous magnesium sulfate for seizure prophylaxis in preeclampsia with severe features and for treatment or prevention of recurrent seizures in eclampsia. Magnesium sulfate is more effective than placebo, antihypertensives, or phenytoin for prevention of first and recurrent eclamptic seizures. jacc+1jaccCardiometabolic Health in Pregnancy: Prevention, Management, and Long-Term ImplicationsWileyHypertension and pregnancy: expert consensus statement from the ...

Undertake delivery for preeclampsia with severe features at 34 weeks' gestation for patients who remain pregnant to that point, after initial maternal stabilization. This timing applies even when the patient appears temporarily stable because severe disease carries ongoing maternal and fetal risk during continued pregnancy. ajog+1ajogpdfajogEvaluation and management of severe preeclampsia before 34 ...

At gestational ages beyond 37 weeks, planned delivery for gestational hypertension or preeclampsia without severe features reduces adverse maternal outcomes without increasing cesarean delivery or neonatal adverse outcomes in the HYPITAT trial context. This evidence does not support applying outpatient expectant management principles to patients with severe features at or beyond 34 weeks.

Choose delivery route according to obstetric factors and urgency rather than the diagnosis alone. When maternal or fetal deterioration is present, stabilize immediately and proceed with delivery; cesarean delivery may be necessary when rapid birth is required or vaginal delivery is not feasible. ajog+1ajogpdfACCOnline Exclusive | From the Member Sections | Optimizing Care of Patients with Hypertensive Disorders of Pregnancy: Putting an Enterprise Plan into Action - American College of Cardiology

For severe preeclampsia before 34 weeks, expectant management can improve neonatal outcomes in selected patients but requires careful in-hospital maternal and fetal surveillance. It is not a strategy for patients who cannot be stabilized or who develop worsening maternal disease or fetal compromise.

Counsel that prolongation is often limited and that delivery indications arise frequently from either fetal or maternal deterioration. In reports of expectant management before 34 weeks, delivery occurred for fetal indications in 46% and maternal indications in 40%; reported complications included placental abruption, pulmonary edema, eclampsia, stroke, stillbirth, and neonatal death. ajogajogpdf

Do not treat fetal growth restriction as an automatic substitute for a full fetal assessment, but recognize it as a marker of uteroplacental disease that may shorten the safe surveillance interval. Fetal compromise during expectant management is an indication to end pregnancy rather than continue solely to gain gestational age.

Preeclampsia and eclampsia can occur before, during, and up to 6 weeks postpartum. For new postpartum hypertension, confirm nonsevere elevations on two occasions at least 4 hours apart, but confirm severe pressure within minutes and treat sustained blood pressure of at least 160/110 mm Hg with rapid-acting therapy within 30 to 60 minutes. jacc+1jaccCardiometabolic Health in Pregnancy: Prevention, Management, and Long-Term ImplicationsajogPostpartum preeclampsia or eclampsia: defining its place and ...

For suspected postpartum preeclampsia, obtain CBC, comprehensive metabolic panel, and urine protein-to-creatinine ratio. In patients with clinical volume overload, consider brain natriuretic peptide; select imaging according to neurologic, cardiopulmonary, or other presenting findings. Severe hypertension alone within 6 weeks postpartum, after other etiologies are excluded, warrants classification and management as postpartum preeclampsia. ajogajogPostpartum preeclampsia or eclampsia: defining its place and ...

At a subsequent pregnancy, prescribe low-dose aspirin 81 mg daily for patients at high risk of preeclampsia, including prior preeclampsia, chronic hypertension, pregestational diabetes, multifetal gestation, or autoimmune disease. For chronic hypertension during pregnancy, treatment targeting blood pressure below 140/90 mm Hg reduced the CHAP trial primary composite outcome without increased fetal growth restriction. jaccjaccCardiometabolic Health in Pregnancy: Prevention, Management, and Long-Term Implications
