Low-dose aspirin does not prevent preeclampsia, but mild cases near term have low risks. Severe preeclampsia before 35 weeks poses the greatest risk to mothers and newborns.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Perinatology

Background:

  • Preeclampsia affects 6-8% of pregnancies, with increased risk in women with pre-existing hypertension, diabetes, or prior preeclampsia.
  • Recent trials show low-dose aspirin offers no benefit in preventing preeclampsia or improving perinatal outcomes.
  • Variations in defining mild and severe preeclampsia exist across centers, particularly in high-risk populations.

Purpose of the Study:

  • To analyze outcomes of preeclampsia based on severity and gestational age.
  • To evaluate the safety of epidural anesthesia in pregnant patients with preeclampsia and those on low-dose aspirin.

Main Methods:

  • Secondary analysis of data from large randomized trials, including Maternal-Fetal Medicine Network studies.

  • Review of medical records to assess definitions and outcomes of preeclampsia.
  • Evaluation of epidural anesthesia safety in specific patient groups.

    • Main Results:

    • Mild gestational hypertension or preeclampsia near term is associated with low maternal and neonatal morbidity.
    • Severe preeclampsia developing before 35 weeks' gestation is linked to the majority of adverse outcomes.
    • Women with prior preeclampsia and/or pre-existing vascular disease face higher risks.
    • Epidural anesthesia is safe for patients receiving low-dose aspirin and those with severe preeclampsia.

    Conclusions:

    • Gestational hypertension and preeclampsia management should consider severity and gestational age.
    • Early-onset severe preeclampsia requires vigilant monitoring and management.
    • Epidural anesthesia can be safely administered to pregnant individuals with preeclampsia on low-dose aspirin.
