Current concepts in intrauterine growth restriction

Area of Science:

• Perinatal Medicine
• Developmental Biology
• Obstetrics

Background:

• Fetal growth is regulated by numerous intrinsic, maternal, and environmental factors.
• Intrauterine growth restriction (IUGR) arises from the complex interplay of these factors, impacting nutrient distribution and fetal development.
• IUGR, while potentially adaptive, is linked to significant short- and long-term health issues.

Purpose of the Study:

• To outline a comprehensive management and follow-up strategy for fetuses and infants experiencing IUGR.
• To emphasize the importance of considering IUGR etiology, timing, and severity in clinical practice.
• To highlight the need for a multidisciplinary approach in managing IUGR.

Main Methods:

• Review of factors contributing to IUGR.
• Analysis of immediate and long-term morbidities associated with IUGR.
• Discussion of a comprehensive, multidisciplinary management framework.

Main Results:

• IUGR is multifactorial, involving fetal, maternal, and environmental influences.
• Short-term morbidities include prematurity and poor nutrient reserves; childhood morbidities involve impaired organ development.
• Long-term effects may be explained by fetal programming, necessitating careful pediatric follow-up.

Conclusions:

• Effective IUGR management demands consideration of its diverse origins and consequences.
• A coordinated, multidisciplinary approach is essential, from obstetrical care to neonatal and pediatric follow-up.
• Further research is crucial for developing novel preventive, diagnostic, and therapeutic strategies for IUGR.
