About this study

Official title: Clinic Features and Long-term Outcome of Different Subgroups of Brochopulmonary Dysplasia in Preterm Infants

This study described the perinatal high-risk factors and clinical manifestations of the children, and compared the high-risk factors, clinical manifestations and prognosis of BPD among different clinical subtypes by comparison between groups. BPD grading was performed using the 2018 grading standard to compare the distribution of I/II/III BPD among different groups.

Early, lethal BPDIn preterm infants(GA<32 weeks and hospital day>14 days ),Some infants who die before 36 weeks PMA (between 14 days of postnatal age and 36 weeks) due to persistent parenchymal lung disease and respiratory failure that can not be attributable to other neonatalmorbidities

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mortality

    Different subtype of BPD infants against the total BPD infants in corresponding group

    Measured: up to 12 months after birth

  2. Serious respiratory mobidities

    occurence of at least one of the following: tracheostomy, continued hospitalization for respiratory reasons at or beyond 50weeks PMA; continued oxygen supplement or respiratory support beyond 12months after birth; readmission for respiratory reasons.

    Measured: up to 18 months after birth

  3. Duration of first hospital stay

    days between admission and first discharge

    Measured: up to 12 months after birth

  4. Days with oxygen supplement

    days during which the infants were given oxygen

    Measured: up to 12 months after birth

  5. Days of Mechanical Ventilation

    days during which the infants were given mechanical ventilation

    Measured: up to 12 months after birth

Secondary outcomes (3)
  1. weight

    the measure of infant's length

    Measured: up to 18months after birth

  2. length

    the measure of infant's weight

    Measured: up to 18months after birth

  3. head circumference

    the measure of infant's head circumference, which is the occipital-frontal circumference

    Measured: up to 18months after birth

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mortality (time frame: up to 12 months after birth). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04237844, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
