Study Notes
Overview of Preeclampsia
- Preeclampsia is a hypertensive, multisystem disorder specific to pregnancy, characterized by endothelial dysfunction and reduced organ perfusion.
Diagnosis
- New onset hypertension after 20 weeks indicates pregnancy-related changes.
- Two blood pressure readings at least 4 hours apart are required, with systolic >140 and diastolic >90 to confirm sustained hypertension.
- Proteinuria >300 mg in 24 hours or a protein/creatinine ratio ≥ 0.3 mg/dl signifies kidney involvement.
- Symptoms may include immune system dysfunction and ischemia due to systemic endothelial damage.
Signs and Symptoms
- Liver ischemia can cause epigastric pain.
- Proteinuria and oliguria arise from kidney damage leading to decreased filtration and urine output.
- Thrombocytopenia results from endothelial damage activating the coagulation cascade.
- Hyperreflexia and severe headaches occur due to cerebral endothelial damage and edema.
- Visual disturbances can stem from retinal artery spasms caused by elevated blood pressure.
- Increased capillary permeability leads to decreased serum albumin and generalized edema.
- Pulmonary edema can occur due to increased vascular resistance and heart failure.
Severe Symptoms
- Blood pressure ≥160/110 on bedrest reflects severe endothelial dysfunction.
- Symptoms like headache and pulmonary edema signal advanced organ involvement and risk of serious complications.
- Abnormal liver and kidney function tests indicate significant ischemic damage.
- HELLP syndrome, characterized by hemolysis, elevated liver enzymes, and low platelets, necessitates immediate delivery.
Lab Evaluation
- Consistent blood pressure readings confirm sustained hypertension essential for diagnosis.
- Urinalysis is crucial for identifying proteinuria, a hallmark of preeclampsia.
- Kidney and liver function tests may reveal dysfunction in severe cases.
- Low platelet counts are indicative of coagulation cascade activation, commonly seen in severe preeclampsia.
Management in Pregnancy
- Outpatient management includes fetal monitoring through NST and BPP to assess oxygenation needs and determine delivery timing.
- Antihypertensives like Labetalol and Hydralazine control maternal blood pressure, mitigating stroke risks while protecting the fetus.
- Magnesium sulfate is used for seizure prophylaxis but is contraindicated in cases of pulmonary edema or renal failure.
- Induction of labor is the only definitive treatment, often necessitating early delivery in severe cases before 34 weeks.
Implications for Timing and Type of Birth
- Timing of induction or C-section depends on the severity of symptoms and fetal health, as preeclampsia resolves post-delivery.
Risks to the Fetus
- Growth restriction can occur due to decreased placental perfusion affecting oxygen and nutrient supply.
- Prematurity may follow early delivery to protect maternal and fetal health.
- Fetal intolerance to labor can arise from poor placental function.
- Severe placental insufficiency risks stillbirth.
Risks to the Pregnant/Birthing Person
- Severe preeclampsia poses risks like stroke, heart failure, and disseminated intravascular coagulation (DIC).
- Maternal risk factors include nulliparity and obesity, affecting cardiovascular, endocrine, and immune responses during pregnancy.
- Eclampsia is defined as the onset of seizures in preeclampsia, marking progression to a severe form of the disorder.
Pathologic Process of Preeclampsia
- Incomplete placental artery transformation results in high-resistance, low-perfusion blood flow, compromising fetal oxygen supply and inducing maternal symptoms.
- Placental dysfunction triggers systemic responses, including inflammation, endothelial damage, vasospasm, and coagulation system activation.
