Study Notes
Hypertensive Disorders
- Hypertensive disorders are a leading cause of maternal and fetal mortality and morbidity, affecting 5-10% of pregnancies. Preeclampsia is a significant contributor to premature birth. Incidence is increasing.
- Classification: gestational hypertension (after 20 weeks, no proteinuria), preeclampsia (after 20 weeks, hypertension and proteinuria or other organ involvement), eclampsia (preeclampsia with seizures), HELLP syndrome (hemolysis, elevated liver enzymes, low platelets), and chronic hypertension (before 20 weeks). Postpartum hypertension is defined as blood pressure above 140/90.
- Gestational Hypertension: hypertension after 20 weeks gestation without proteinuria or other systemic findings. 25-50% of cases progress to preeclampsia. Resolves postpartum, but follow-up is needed. Requires blood pressure monitoring and potentially further investigation if elevated.
- Preeclampsia: pregnancy-specific condition characterized by hypertension and proteinuria after 20 weeks gestation, or hypertension with thrombocytopenia, impaired liver function, renal insufficiency, pulmonary edema, or neurological symptoms. Risk factors include nulliparity, obesity, multiple gestation, prior preeclampsia, chronic hypertension, diabetes, renal disease, autoimmune disease, age ≥35, assisted reproductive technology, and limited sperm exposure.
- Preeclampsia Pathophysiology: placental dysfunction leading to poor perfusion is the root cause. Spiral arteries fail to remodel properly, resulting in ischemia and endothelial cell damage, initiating a cascade of events leading to vasospasm and organ damage.
- Preeclampsia Organ Damage: Reduced kidney perfusion causes decreased glomerular filtration rate, proteinuria, elevated uric acid, and fluid retention. Reduced liver perfusion leads to elevated liver enzymes and potential hepatic rupture. Cerebral edema and vasospasm cause headache, hyperreflexia, clonus, seizures, and visual disturbances.
- Preeclampsia Care Management: Goals are maternal and fetal safety. Strategies include early risk assessment, low-dose aspirin (81 mg/day for high-risk women), frequent monitoring (BP, edema, reflexes, proteinuria, 24-hr urine collection or PCR), and rapid intervention for severe features.
- Preeclampsia - Care Management: Gestational hypertension and mild preeclampsia may be managed at home with frequent monitoring. Severe preeclampsia requires hospitalization, magnesium sulfate (to prevent seizures), and antihypertensive medication (if BP ≥160/110). Close fetal monitoring is essential.
- Eclampsia: Onset of seizures in a woman with preeclampsia. Requires immediate management including magnesium sulfate.
- HELLP Syndrome: Hemolysis, Elevated Liver enzymes, Low Platelets. A severe complication of preeclampsia.
Hemorrhagic Disorders
- Early Pregnancy Bleeding: Causes include miscarriage, ectopic pregnancy, and cervical insufficiency.
- Miscarriage: Spontaneous loss of pregnancy before 20 weeks. Management depends on the type of miscarriage and gestational age, ranging from expectant management to surgical intervention.
- Ectopic Pregnancy: Implantation of the fertilized ovum outside the uterine cavity. Can be life-threatening due to potential rupture and internal bleeding. Management includes medication or surgery.
- Cervical Insufficiency: Premature dilation of the cervix leading to spontaneous abortion. Management involves cerclage or other interventions to maintain pregnancy.
- Placenta Previa: Placenta implants low in the uterus, partially or completely covering the cervix. Characterized by painless vaginal bleeding.
- Placental Abruption: Premature separation of the normally implanted placenta from the uterine wall. Characterized by painful vaginal bleeding, uterine tenderness, and fetal distress.
- Disseminated Intravascular Coagulation (DIC): A serious clotting disorder often triggered by obstetric complications like placental abruption, preeclampsia/HELLP, amniotic fluid embolism, postpartum hemorrhage, severe sepsis, acute fatty liver of pregnancy, and retained dead fetus. Management focuses on treating the underlying cause and supportive care (fluid resuscitation, blood products, etc.).
