Breathing Easier: New Study Finds Extended CPAP Improves Lung Growth in Preterm Infants

Premature birth presents numerous challenges for newborns, especially regarding lung development. Preterm infants often experience underdeveloped lungs, increasing their risk of respiratory problems throughout their lives. Now, a groundbreaking study offers a beacon of hope, revealing a simple yet effective method for promoting healthy lung growth in these vulnerable infants. Researchers at Oregon Health & Science University (OHSU) have found that extending the duration of continuous positive airway pressure (CPAP) treatment significantly improves lung growth and function in preterm infants. This discovery, published in the American Journal of Respiratory and Critical Care Medicine, has the potential to transform neonatal care and improve the long-term respiratory health of millions of children.

The Promise of Extended CPAP: A Simple Solution with Profound Impact

CPAP, a non-invasive respiratory support technique, delivers pressurized air through nasal prongs or a mask to keep the airways open. It’s standard practice for preterm infants experiencing respiratory distress. While early CPAP application is routine, doctors typically discontinue treatment once the infant’s breathing stabilizes. The OHSU research team questioned this conventional approach, hypothesizing that extending CPAP duration could further enhance lung development. They designed a randomized controlled trial involving 100 stable preterm infants. The researchers extended CPAP treatment for an additional two weeks beyond the typical duration. The results were striking. Infants receiving extended CPAP demonstrated significantly larger lung volumes at six months post-discharge, indicating substantial lung growth improvement. These infants also showed improved pulmonary gas exchange, more efficient oxygen and carbon dioxide diffusion in their lungs, and better overall airway function. Moreover, they experienced less wheezing throughout their first year.

Impact and Implementation: Changing Neonatal Care for the Better

These findings highlight the potential of a simple, non-pharmacological intervention to reshape the trajectory of lung disease in preterm infants. Dr. Cindy McEvoy, the study’s principal investigator and a professor of pediatrics at OHSU’s School of Medicine, emphasizes the transformative potential of this discovery. She states, “Adjusting the duration of CPAP application offers a safe and actionable method to positively influence lung development.” Extending CPAP therapy offers a cost-effective way to significantly improve outcomes, potentially reducing chronic respiratory illnesses, healthcare costs, and enhancing the quality of life for preterm infants. OHSU Doernbecher Children’s Hospital has already implemented this extended CPAP protocol in its NICU, witnessing positive results. Many NICUs across the country are now evaluating their CPAP practices based on these findings, signaling a potential shift in the standard of care for preterm infants. This research offers a powerful example of how a minor adjustment in clinical practice can produce significant benefits, providing a brighter future for preterm infants and their families.

Preterm Birth and Lung Development Challenges: A Broader Perspective

Preterm birth, defined as birth before 37 weeks of gestation, affects approximately 10% of births in the United States, translating to roughly 400,000 infants annually. The immature lungs of preterm infants face significant developmental challenges. These underdeveloped lungs often lack sufficient surfactant, a substance crucial for keeping the air sacs open. This deficiency can lead to respiratory distress syndrome (RDS), a serious condition characterized by labored breathing and low blood oxygen levels. Beyond RDS, preterm infants are at increased risk for bronchopulmonary dysplasia (BPD), a chronic lung disease that can require prolonged oxygen therapy and ventilation. Even after leaving the NICU, preterm infants remain vulnerable to respiratory infections, wheezing, and asthma, which can impact their long-term health and quality of life. Therefore, the findings of this study offer a significant step forward in mitigating these risks and providing preterm infants with a better chance of healthy lung development.
