NCT04237844

Brief Summary

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.

Outcome Measures

Primary Outcomes (5)

  • Mortality

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

    up to 12 months after birth

  • 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.

    up to 18 months after birth

  • Duration of first hospital stay

    days between admission and first discharge

    up to 12 months after birth

  • Days with oxygen supplement

    days during which the infants were given oxygen

    up to 12 months after birth

  • Days of Mechanical Ventilation

    days during which the infants were given mechanical ventilation

    up to 12 months after birth

Secondary Outcomes (3)

  • weight

    up to 18months after birth

  • length

    up to 18months after birth

  • head circumference

    up to 18months after birth

Study Arms (5)

no BPD

In preterm infants(GA\<32 weeks and hospital day\>14 days ),infants without BPD

classic BPD

In preterm infants(GA\<32 weeks and hospital day\>14 days ),There are clinical manifestations and imaging evidence of RDS after birth, the condition is not relieved, FiO2 lasts \>25%

BPD after RDS

In preterm infants(GA\<32 weeks and hospital day\>14 days ),There are clinical manifestations and imaging evidence of RDS after birth. FiO2\<23% within 7 days, and the condition is aggravated to FiO2\>25%.

Delayed BPD

In preterm infants(GA\<32 weeks and hospital day\>14 days ),There is no RDS performance after birth, FiO2 lasts \<25%

Early, lethal BPD

In 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
