This is the complete MD/MS OBGyn-level chapter. Here is a structural overview of what was covered:
What this chapter covers:
Part I - Hypertensive Disorders of Pregnancy
- ACOG classification table (gestational HTN, preeclampsia, eclampsia, chronic HTN, superimposed PE)
- Epidemiology: incidence ~85/1000 deliveries; nulliparity the greatest attributable risk
- Full pathophysiology: the two-stage model (shallow placentation → endothelial dysfunction), sFLT-1/VEGF/PlGF axis, prostacyclin-thromboxane imbalance, nitric oxide reduction, RAAS paradox, hemodynamic changes
- Diagnostic criteria including severe features (updated ACOG 2013 criteria - no longer requires proteinuria if severe features present)
- HELLP syndrome: Tennessee classification, complications, management
- Management tables: expectant management thresholds by gestational age, antihypertensive drugs with doses, MgSO4 protocol + toxicity monitoring, Magpie trial evidence
- Eclampsia: PRES neuroimaging, acute management algorithm, postpartum seizures
- Long-term cardiovascular implications (AHA recognized risk factor for CVD)
Part II - Extragenital Pathologies
- Diabetes in Pregnancy: White's classification, GDM pathophysiology (insulin resistance curve), both screening approaches (one-step IADPSG and two-step ACOG), full fetal/neonatal complications table (including caudal regression syndrome), pgDM management (preconception HbA1c targets, insulin strategies, CGM evidence, delivery timing), GDM management (MNT first, insulin preferred, metformin vs. glyburide comparison), mandatory postpartum OGTT
- Uterine Fibroids in Pregnancy: Red degeneration (mechanism + management), location-specific complications, obstetric complications table, conservative management principles, when to do cesarean myomectomy
Part III - Integration tables including differential diagnosis, antihypertensive safety, high-yield one-liners, and a visual management algorithm for severe preeclampsia
