The infant with bronchopulmonary dysplasia on home oxygen: The oxygen weaning conundrum in the absence of good evidence.

Bronchopulmonary dysplasia [BPD] is the most common complication of extremely preterm delivery and its optimal management remains challenging because of a lack of evidence to guide management. There has been improvement in the management of evolving BPD in the neonatal intensive care unit (NICU). The threshold for provision of home oxygen therapy, often occurring because of a preference for earlier discharge from the NICU, creates tensions for clincians and families. Once discharged in supplemental oxygen, the approaches for the weaning of this therapy vary considerably across the world. Regardless of guidelines and multidisciplinary team support, up to a third of families of an infant with BPD elect to withdraw home oxygen therapy independently of medical advice. There is a pressing need to derive evidence to better inform practice, generate international consensus and undertake large, appropriately funded, longitudinal studies of BPD with clinically meaningful outcomes (respiratory, cardiovascular and neurodevelopmental) from infancy to adulthood.
