About this trial

This study examines the respiratory outcomes of preterm infants born at gestational ages less than 29 weeks, spanning from birth to 24 months corrected age. It delves into the intricacies of respiratory function impairment attributable to diverse factors, such as respiratory distress syndrome, bronchopulmonary dysplasia, postnatal corticosteroids, ventilatory support, as well as nutritional aspect during NICU stay. Furthermore, it scrutinizes the incidence of chronic respiratory diseases stemming from these conditions, assessing their long-term impact on respiratory prognosis post-discharge. In addition to respiratory aspects, the research extends its focus to the growth and developmental outcomes of preterm infants. By synthesizing these multifaceted elements, the study aspires to enhance current treatments and preventative measures for respiratory conditions in preterm infants.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Infants born at gestational age less than 29 weeks with cohort consent obtained within 7 days of birth

Disqualifiers

death within 3 days of birth

severe structural heart defects

structural abnormalities in the upper airway, lungs, or chest

congenital anomalies that may impact cardiopulmonary function

Trial population

This study is a multicenter cohort study conducted by a total of 7 institutions (Seoul National University Hospital, Severance Hospital, Asan Medical center, Samsung Medical Hospital, Ajou University Hospital, Bundang Seoul National University Hospital, Chonnam National University Hospital) jointly. It includes all preterm infants born at these hospitals from March 2022 to December 2024, who are born at a gestational age of less than 29 weeks and are admitted to the neonatal intensive care unit.
