Study Notes
Hypertensive Disorders in Pregnancy
- Hypertensive disorders of pregnancy are a leading cause of maternal and perinatal mortality worldwide.
Definitions and Diagnostic Criteria
- Preeclampsia (PE) is defined as:
- Systolic blood pressure at ≥140 mm Hg
- Diastolic blood pressure at ≥90 mm Hg in normotensive women
- Accompanied by one or more of the following new onset conditions at or after 20 weeks of gestation
- Conditions that accompany PE:
- Proteinuria (≥30 mg/mol protein: creatinine ratio; ≥300 mg/24 hour; or ≥2+ dipstick)
- Evidence of other maternal organ dysfunction:
- Acute kidney injury
- Liver involvement
- Neurological complications
- Hematological complications
- Uteroplacental dysfunction:
- Fetal growth restriction
- Abnormal umbilical artery doppler waveform analysis
- Stillbirth
