The purpose of this study was to assess changes in neonatal ventilation practices for ELBW infants and compare outcomes between two epochs (2005–2009 vs. 2010–2015) to analyze progression stemming from the implementation of newer clinical guidelines. Materials and methodsWe conducted a retrospective study with data collection from all ELBW infants born between 2005 and 2015 in our center through their individual clinical records. The main outcome was the prevalence of bronchopulmonary dysplasia (BPD) in both periods. Assessment of other morbidities and survival were secondary outcomes. ResultsA hundred and thirty-one infants were included; median gestational age of 27 weeks (23–33) and mean birth weight of 794.58g (±149.37). Invasive mechanical ventilation (IMV) was performed on 103 (78.6%) infants. Non-significant increases in the use of non-invasive mechanical ventilation (NIMV) were observed between epochs both exclusively and following IMV. In conventional ventilation there were significant variations between epochs, namely a decrease in synchronized intermittent mandatory ventilation (SIMV) and a major growth in the addition of volume guarantee (VG). Significant decreases in BPD (from 50.9% to 32.0%) and cystic periventricular leukomalacia (cPVL) (from 27.5% to 10.7%) were observed between epochs, with no major changes in other morbidities and survival. ConclusionChanges in our neonatal intensive care unit's ventilatory practices according to the most up-to-date guidelines, have led to a decrease in BPD and cPVL, over an 11-year period. ER -
