Early lung development in preterm babies with and without fetal growth restriction

Early Lung Function Trajectories: Comparison Between Infants With Intrauterine Growth Restriction and Appropriately Grown Ones.

Observational Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT06919757

This study will test whether ultrasound measurements of fetal lung volume, diaphragm thickness and heart function before 32 weeks can help predict breathing problems and later lung function in preterm babies with or without fetal growth restriction.

What this trial studies

This prospective observational study follows fetuses diagnosed before 32 weeks and the infants they become, comparing those with fetal growth restriction to those without. Investigators will perform prenatal ultrasound measurements of lung volumes, diaphragm thickness and contractility, and cardiac kinetics, then record perinatal complications and respiratory outcomes after birth. Pulmonary function tests and oxygenation/respiratory monitoring will be used in the neonatal period and early childhood to link prenatal measures with later lung function. No interventional therapy is assigned; the study aims to identify ultrasound markers that correlate with respiratory risk in prematurity.

Who should consider this trial

Good fit: Ideal candidates are fetuses and infants born before 32 weeks of gestation, with or without fetal growth restriction, whose parents provide informed consent and who do not have major malformations or need palliative care.

Not a fit: Patients unlikely to benefit include those receiving palliative care, those with major congenital malformations, and infants born at or after 32 weeks of gestation.

Why it matters

Potential benefit: If successful, the findings could help identify which preterm infants are at higher risk for breathing problems so clinicians can target monitoring and early respiratory care.

How similar studies have performed: Prior studies have linked fetal growth restriction to worse respiratory outcomes and some small studies suggest prenatal lung measurements relate to neonatal respiratory status, but large prospective comparisons remain limited.
