Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are preterm infants born between 29 to 33 weeks of gestational age who are at least 34 weeks corrected age and off respiratory support.
✕Probably not a fit
Patients who are on respiratory support greater than 1.5 liters per minute or have congenital anomalies may not benefit from this study.

What this trial studies
This study aims to investigate the effects of womb-like sound exposure on the respiratory control development in preterm infants. By providing audio recordings that mimic the womb environment, researchers hope to enhance neuronal maturation in the brain regions responsible for respiratory control. The study will monitor changes in cardiorespiratory patterns, specifically looking for reductions in apnea, bradycardia, and intermittent hypoxemia. This approach is designed to offer a low-risk intervention during a critical period of brain development for these vulnerable infants.
Why it matters
Potential benefit: If successful, this intervention could significantly improve respiratory stability and overall health outcomes for preterm infants.
How similar studies have gone: While the specific approach of using womb recordings is novel, similar studies exploring sound exposure in neonatal care have shown promising results.
