The association of the room air challenge with long-term outcomes in extremely preterm infants
摘要
Evaluate the association between results of the room air (RA) challenge and death, respiratory morbidity, and neurodevelopmental impairment (NDI) at 2 years' corrected age.
Study designCohort study of infants born <27 weeks’ gestational age who underwent a RA challenge to determine BPD diagnosis at 36 weeks postmenstrual age.
ResultsOf 1022 infants eligible for the RA challenge, 554 underwent testing and 223 passed. Test result was not associated with death or serious respiratory morbidities [adjusted relative risk (aRR) 1.01, 95% confidence interval (CI) 0.65–1.56] or death or moderate/severe NDI (aRR 1.06, 95% CI 0.81–1.39) at 2 years.
ConclusionResults of the RA challenge were not associated with differences in respiratory or neurodevelopmental morbidity at 2 years, suggesting the RA challenge does not add prognostic value in contemporary extremely preterm infants.
