Pre-eclampsia: fetal assessment and neonatal outcomes

Area of Science:

• Obstetrics and Gynecology
• Perinatal Medicine
• Neonatology

Background:

• Pre-eclampsia is linked to significant perinatal and neonatal complications, impacting birth weight and gestational age.
• Current antenatal testing methods for pre-eclampsia, like fetal movement counts and biophysical profiles, have limitations.
• Umbilical artery and venous Doppler velocimetry show promise for evaluating fetuses in pre-eclampsia cases, particularly with placental insufficiency.

Purpose of the Study:

• To review current antenatal testing modalities for pre-eclampsia.
• To assess the role of Doppler velocimetry in managing pre-eclampsia.
• To explore the short- and long-term outcomes for infants born to mothers with pre-eclampsia.

Main Methods:

• Literature review on antenatal testing for pre-eclampsia.
• Analysis of evidence supporting Doppler velocimetry in pre-eclampsia management.
• Examination of perinatal and neonatal complications associated with pre-eclampsia.

Main Results:

• Fetal movement counts and biophysical profiles have significant limitations for pre-eclampsia monitoring.
• Umbilical artery and venous Doppler velocimetry are increasingly supported for evaluating fetuses affected by pre-eclampsia, especially with placental insufficiency.
• Pre-eclampsia may offer a survival advantage for small or preterm infants, but long-term neurodevelopmental outcomes remain unclear.

Conclusions:

• Umbilical artery and venous Doppler velocimetry show potential as optimal antenatal testing for pre-eclampsia.
• While pre-eclampsia may improve survival for some infants, its impact on long-term neurodevelopment requires further investigation.
• Abnormal umbilical artery flows may indicate poorer cognitive outcomes, though evidence is not definitive.
