Study Notes
Hypertensive Complications in Pregnancy Overview
- Hypertensive disorders affect 5–10% of pregnancies.
- Include a spectrum of conditions from chronic hypertension to severe preeclampsia.
Diagnosis of Hypertensive Disorders
- Chronic hypertension (CHTN) is defined as blood pressure ≥ 140/90 mmHg prior to 20 weeks of gestation.
- Gestational hypertension occurs after 20 weeks with sustained BP ≥ 140/90 mmHg without proteinuria.
- Preeclampsia involves hypertension with proteinuria after 20 weeks.
Types of Hypertensive Disorders
- Chronic Hypertension (CHTN): History of hypertension before pregnancy.
- Gestational Hypertension: New onset hypertension after 20 weeks.
- Preeclampsia without Severe Features: Hypertension with proteinuria but no severe manifestations.
- Superimposed Preeclampsia: Development of preeclampsia in women with existing hypertension.
- Preeclampsia with Severe Features: Defined by specific criteria such as severe BP elevations or end-organ dysfunction.
- HELLP Syndrome: Characterized by hemolysis, elevated liver enzymes, and low platelet count.
- Eclampsia: The occurrence of seizures in a patient with preeclampsia.
Etiopathogenesis of Hypertensive Disorders
- Chronic hypertension is often a primary condition, where 90% of cases are essential hypertension.
- Can be influenced by genetics and environmental factors.
Clinical Management
- Management may include oral antihypertensive medications in outpatient settings.
- Magnesium sulfate is used for seizure prophylaxis in severe cases.
- Monitor magnesium sulfate levels to avoid respiratory depression, aiming for 4-7 mEq/L.
Prediction and Prevention
- Low-dose aspirin may help prevent hypertensive disorders in high-risk women.
- Routine monitoring of BP is essential in pregnant patients.
Disturbances in Organ Systems
- Hypertensive conditions can impact various organs, leading to increased morbidity and mortality.
- Uteroplacental perfusion issues may result in fetal growth restrictions.
Dexamethasone Administration in HELLP Syndrome
- Aimed to decrease renal failure incidence post-partum.
Common Clinical Scenarios
- Severe headache and elevated BP in pregnancy may indicate severe hypertension needing immediate management.
- A patient losing patellar reflexes on magnesium sulfate may have plasma levels between 10-11 mEq/L.
Management Guidelines for Specific Cases
- For patients with severe preeclampsia, magnesium sulfate is a preferred treatment to prevent seizures.
- If a patient exhibits blurring vision and epigastric pain with high BP, management includes serial CBC and liver enzyme checks.
Important Classifications
- Tennessee Classification for HELLP Syndrome:
- Requires abnormal peripheral smear, elevated LDH or bilirubin, and elevated liver enzymes.
- Recognize that essential hypertension is defined as hypertension not secondary to other conditions.
Key Takeaways
- Close monitoring and timely interventions are critical in managing hypertensive disorders during pregnancy.
- Understanding and recognizing the signs and symptoms of each condition can lead to better maternal and fetal outcomes.
