Ultrasound may spot problems with placenta linked to low birth weight

New research from Amsterdam UMC sheds light on the complexities of “small for gestational age” (SGA) fetuses, offering a promising tool for better understanding and managing this common prenatal concern.

The Challenge of Small Fetuses:

Approximately 10% of fetuses are identified as SGA during ultrasounds, raising concerns about their well-being. While some of these babies thrive after birth, others face potential dangers due to a poorly functioning placenta, often necessitating early delivery.

Beyond Standard Ultrasounds:

This study goes beyond traditional ultrasounds by utilizing “Doppler ultrasound,” which meticulously examines blood flow within the umbilical cord and fetal brain. This advanced technique helps identify crucial clues about placental health.

Key Findings:

Doppler clues: Reduced blood flow or abnormally high blood flow in the brain can indicate a struggling placenta, potentially endangering the fetus.
Precision matters: By analyzing these Doppler readings, doctors can accurately determine which SGA babies require close monitoring due to placental issues.
Reduced interventions: For SGA babies with healthy placental function, less intensive monitoring allows for a higher chance of natural, undisturbed delivery.
Early delivery not always beneficial: Contrary to previous assumptions, researchers found that inducing labor before 37 weeks for suspected placental problems does not improve outcomes. This suggests staying in the womb longer might be best for the baby’s development.

The Significance:

This innovative approach using Doppler ultrasound empowers healthcare professionals to:

Differentiate: Accurately distinguish between SGA babies with healthy placentas and those with potential risks.
Tailored care: Offer targeted monitoring and intervention for babies truly in need, potentially reducing unnecessary interventions for others.
Natural delivery: Increase the possibility of natural childbirth for low-risk SGA babies, enhancing the birthing experience.

The Future:

Though further research is needed, this study lays the groundwork for a valuable tool in managing SGA pregnancies. By incorporating Doppler analysis into prenatal care, doctors can make more informed decisions and optimize pregnancy outcomes for both mother and baby.
