Intrauterine growth retardation

Area of Science:

• Obstetrics and Gynecology
• Fetal Medicine
• Neonatal Health

Background:

• Intrauterine Growth Restriction (IUGR) poses significant risks, including stillbirth and neonatal complications, yet is often undetected.
• Current fetal surveillance methods are inadequate for population screening, highlighting the need for better identification of at-risk fetuses.

Purpose of the Study:

• To develop and describe a computerized method for predicting optimal fetal weight tailored to individual pregnancies.
• To improve the distinction between constitutional smallness and pathological IUGR.

Main Methods:

• A computerized system was developed to predict optimal birthweight, adjusted for maternal factors (height, booking weight, ethnicity, parity).
• This prediction establishes an expected fetal weight gain velocity.
• Preterm fetal weights are assessed against a fetal weight norm, not a standard derived from non-physiological deliveries.

Main Results:

• The individualized prediction enhances the ability to differentiate between constitutional and pathological fetal smallness.
• Customized growth charts enable screening for growth retardation via serial fundal height measurements.
• Ultrasound estimation of fetal weight and referral for intensive surveillance are used as necessary.

Conclusions:

• The described method provides an individualized approach to assessing fetal growth and identifying IUGR.
• This improves screening accuracy by establishing appropriate standards for fetal weight assessment and growth velocity.
• The approach supports timely intervention for high-risk fetuses, potentially reducing adverse outcomes.
