Management of fetal growth restriction: an evidence-based approach

Area of Science:

• Perinatal Medicine
• Fetal Medicine
• Obstetrics

Background:

• Fetal growth restriction (FGR) is a significant concern in perinatal medicine, associated with increased risk of adverse outcomes.
• Effective management strategies are crucial for improving fetal well-being and reducing neonatal morbidity and mortality.
• Current guidelines emphasize a multi-faceted approach to FGR management.

Purpose of the Study:

• To present an evidence-based framework for the management of fetal growth restriction (FGR).
• To detail the components of fetal surveillance, intervention timing, and etiological management in FGR.
• To provide a clinical management guideline for healthcare providers caring for fetuses with FGR.

Main Methods:

• Comprehensive review of existing literature on fetal growth restriction management.
• Analysis of diagnostic tools including umbilical arterial (UA) Doppler sonography, nonstress test (NST), amniotic fluid assessment, biophysical profile (BPP), and venous Doppler sonography.
• Synthesis of evidence to formulate management recommendations.

Main Results:

• Umbilical arterial (UA) Doppler sonography is identified as the primary surveillance tool for FGR.
• Ominous signs such as absent or reversed end-diastolic flow in UA Doppler, non-assuring NST, low BPP, and abnormal fetal venous flow patterns indicate the need for intervention.
• A combination of surveillance methods provides a comprehensive assessment of fetal status.

Conclusions:

• An evidence-based approach to FGR management involves appropriate fetal surveillance, timely intervention, and selective etiological management.
• Individualization of care based on specific fetal and maternal factors is recommended.
• Adherence to established guidelines can optimize outcomes for fetuses diagnosed with FGR.
