Understanding long-term effects of breathing patterns in preterm infants

Post-Vent, the Sequelae: Personalized Prognostic Modeling for Consequences of Neonatal Intermittent Hypoxemia in Preterm Infants at Pre-School Age

Observational Ann & Robert H Lurie Children's Hospital of Chicago · NCT05336890

This study looks at how breathing problems in preterm babies might affect their chances of developing asthma, sleep issues, and learning difficulties as they grow up.

What this trial studies

This observational study aims to investigate the long-term consequences of neonatal intermittent hypoxemia on preterm infants, particularly focusing on conditions like asthma, sleep-disordered breathing, and neurodevelopmental disorders. By analyzing data from the Pre-Vent cohort, the study seeks to identify specific breathing patterns that may predict these outcomes. The research will explore the relationship between early postnatal hypoxemia events and later respiratory and neurological functions, with the goal of informing future prevention and intervention strategies.

Who should consider this trial

Good fit: Ideal candidates for this study are preterm infants born at less than 29 weeks gestational age who are under 7 years old.

Not a fit: Patients who were withdrawn from the Pre-Vent study or lack physiological data recorded will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection and intervention strategies for preterm infants, potentially reducing the incidence of asthma, sleep-disordered breathing, and neurodevelopmental impairments.

How similar studies have performed: While there is emerging evidence linking intermittent hypoxemia to poor outcomes in preterm infants, this specific approach to understanding the relationship between breathing patterns and long-term effects is relatively novel.
