Abstract

Objective: To determine whether a room air challenge (RAC) correlates with duration of respiratory support for infants with bronchopulmonary dysplasia (BPD). Study design: Prospective study of preterm infants with BPD from 2015–2018. Infants receiving ≤2 liters flow at 36 weeks post-menstrual age (PMA) underwent RAC. Cox regression was used to adjust the duration of respiratory support after 36 weeks PMA for significant covariates. Results: Of 161 infants with BPD, 91 were eligible for RAC; 51 passed and 40 failed. Infants who failed RAC had longer respiratory support after 36 weeks PMA than infants who passed (median 19 weeks (IQR 15–33) versus 2 weeks (IQR 1–8, p

Abstract

BACKGROUND: Predischarge capillary blood gas partial pressure of carbon dioxide (pCO(2)) has been associated with increased adverse events including readmission. This study aimed to determine if predischarge pCO(2) or 36-week pCO(2) was associated with increased respiratory readmissions or other pulmonary healthcare utilization in the year after neonatal intensive care unit (NICU) discharge for infants with bronchopulmonary dysplasia (BPD) discharged with home oxygen, using a standardized outpatient oxygen weaning protocol. METHODS: This was a secondary cohort analysis of infants born
