Study Notes
- Hypertensive disorders in pregnancy include gestational hypertension, pre-eclampsia, and eclampsia, contributing to maternal and perinatal morbidity and mortality.
- Gestational hypertension is high blood pressure before or early in pregnancy, while pre-eclampsia involves high blood pressure with proteinuria, and eclampsia adds seizures to pre-eclampsia.
- Complications of these disorders include multi-organ dysfunction like renal failure, hepatic failure, CNS hemorrhage, stroke, pulmonary edema, placental abruption, and disseminated intravascular coagulation.
- Pre-eclampsia can lead to growth restriction, prematurity, and perinatal death in the baby, making it the third leading cause of maternal mortality in the U.S.
- Normal blood pressure changes during pregnancy include a decrease in the first two trimesters and a rise in the third trimester.
- Pre-eclampsia is unique to pregnancy and typically resolves postpartum, characterized by hypertension and proteinuria due to glomerular filtration barrier dysfunction.
- Risk factors for pre-eclampsia include first-time pregnancy, diabetes mellitus, chronic hypertension, twin pregnancies, but the exact cause is unknown.
- Placental ischemia plays a key role in pre-eclampsia development, leading to oxidative stress, inflammation, endothelial dysfunction, and activation of the coagulation system.
- Criteria for severe pre-eclampsia include severe hypertension, severe proteinuria, oliguria, visual disturbances, pulmonary edema, epigastric pain, impaired liver function, thrombocytopenia, and fetal growth restriction.
- HELLP syndrome is a severe variant of pre-eclampsia characterized by hemolysis, elevated liver enzymes, and low platelets, occurring in around 0.1 to 0.2% of pregnancies and necessitating close monitoring and potentially early delivery.
