NCT03346343

Brief Summary

The purpose of this observational study is to measure pulmonary function in term and preterm infants with and without pulmonary disease including respiratory distress syndrome, bronchopulmonary dysplasia, transient tachypnea of the newborn, meconium aspiration syndrome, and response to treatments given to newborn infants with lung diseases using a non-invasive airway oscillometry system.

Outcome Measures

Primary Outcomes (1)

Secondary Outcomes (4)

  • R7-20

    40 weeks' postmenstrual age or discharge until 2 years

  • R7

    40 weeks' postmenstrual age or discharge until 2 years

  • X7

    40 weeks' postmenstrual age or discharge until 2 years

  • Longer-term Pulmonary Outcomes

    Up to 2 years

Study Arms (1)

Non-invasive forced airway oscillometry

EXPERIMENTAL

Analyze lung function using forced airway oscillometry in preterm infants and term infants with and without lung disease with both cross-sectional and longitudinal comparisons. Aim 1: Lung function in term and preterm infants without lung disease (anticipated n=264) Aim 2: Lung function in preterm infants with respiratory distress syndrome (RDS) who develop bronchopulmonary dysplasia (BPD) and preterm infants with RDS who do not develop BPD (anticipated n=264) Aim 3: Lung function measurements in infants with common neonatal lung diseases (including RDS, BPD, meconium aspiration syndrome, and transient tachypnea of the newborn) and controls without lung disease (anticipated n=570) Aim 4: Lung function in infants with lung disease before and after common therapeutic interventions

Device: Non-invasive forced airway oscillometry

Interventions

This is a non-invasive device will measure lung function in spontaneously breathing infants. Infants will have a cushioned mask placed on his/her face and the device will take measurements as the infant breathes normally.
