Fetal growth restriction: current perspectives

Area of Science:

• Obstetrics and Gynecology
• Perinatal Medicine
• Fetal Development

Background:

• Intrauterine growth restriction (IUGR) is a significant complication in modern obstetrics.
• Current definitions often use the 10th percentile, but adverse outcomes are more concentrated below the 3rd or 5th percentile.
• Understanding IUGR is crucial for improving perinatal outcomes.

Purpose of the Study:

• To review the causes and clinical implications of intrauterine growth restriction (IUGR).
• To provide insights for practical clinical management of IUGR.
• To synthesize evidence on interventions for preventing or treating IUGR.

Main Methods:

• Systematic review of randomized controlled trials (RCTs).
• Analysis of evidence regarding maternal, fetal, and placental causes of IUGR.
• Literature search for interventions related to IUGR.

Main Results:

• Identified maternal, fetal, and placental factors contributing to IUGR.
• Found limited evidence supporting beneficial interventions for IUGR prevention or treatment from RCTs.
• Highlighted the concentration of adverse perinatal outcomes in the most severely growth-restricted infants.

Conclusions:

• Intrauterine growth restriction (IUGR) presents complex challenges in obstetrics.
• Clinical practice guidelines for IUGR require further evidence-based support.
• Effective interventions for IUGR remain an area needing significant research and development.
