简要总结
Bronchopulmonary dysplasia (BPD), or chronic lung disease of prematurity, affects nearly half of extremely preterm infants.This study evaluates the use of supplemental oxygen to manage infants with established BPD. Participants will be randomly placed in either a higher oxygen saturation group or a lower oxygen saturation target group.
详细描述
Bronchopulmonary Dysplasia is diagnosed only in babies who are born prematurely, and affects about half of extremely preterm infants. The incidence of BPD has increased over time. It is most commonly defined as oxygen dependence at 36 weeks postmenstrual age (PMA).
Infants with BPD face more than doubled odds of death after 36 weeks PMA or disability at 5 years compared to preterm infants without BPD. BPD is associated with abnormal lung function throughout childhood and significantly increases health care costs. Cognitive and respiratory outcomes are closely linked throughout the life course; thus, optimal long--term management of BPD during infancy may ultimately improve cognitive outcomes of this high--risk population.
Supplemental oxygen is a lifesaving therapy for premature infants; yet, there is limited evidence about the safety or efficacy of using supplemental oxygen to target higher versus lower oxygen saturations in infants with established BPD.
Infants between the ages of 34-44 weeks post-menstrual age with moderate or severe BPD will be randomly assigned to higher or lower oxygen saturation target ranges. The study intervention will begin in the hospital and will continue at home until 6 months corrected age. When infants are discharged with supplemental oxygen, this will be titrated according to a study algorithm in order to ensure that the target saturations are maintained throughout the study period.
