Extracorporeal life support use in patients with bronchopulmonary dysplasia: A single center case series.

ABSTRACT

PURPOSE: Preterm pediatric patients with bronchopulmonary dysplasia (BPD) represent a subgroup previously deemed high risk candidates for ECLS (extracorporeal life support) due to suspected high mortality or increased post ECLS morbidity. The aim of this study was to determine outcomes for patients with an established history of BPD who subsequently required ECLS. METHODS: A single center retrospective review was performed between 01/2010-06/2022 for patients less than 2 years of age, born prematurely (<32 weeks) with a subsequent diagnosis of BPD, and who required ECLS for respiratory failure. Demographic and clinical data, including ECLS data, were collected. Speech, language, feeding/swallowing, cognitive, hearing, vision, or motor function deficits were obtained with a median follow up of 42 months following discharge. RESULTS: Nineteen patients met criteria. The median birth weight and gestational age was 0.86 kg (IQR 0.73, 1.0) and 26 weeks (IQR 25, 27), respectively. The median chronological age at cannulation was 12.1 months. The most common etiologies for respiratory failure requiring ECLS were viral (68.4%) and bacterial (21.1%) pneumonia. Survival to decannulation was 78.9% (15/19) and survival to hospital discharge was 63.2% (12/19). Amongst survivors to discharge, 42% (5/12) required new or additional home oxygen and 50% (6/12) were noted to have neurodevelopmental/behavioral concerns on follow up at 1 year with 25% (3/12) with concerns beyond a year. CONCLUSION: Patients with underlying BPD who require ECLS have comparable mortality and long-term neurodevelopmental outcomes to non-BPD patients with respiratory failure. This information can be useful when considering ECLS candidacy and providing family counseling.
