BackgroundThe use of lung ultrasound score (LUS) to predict bronchopulmonary dysplasia (BPD) is still evolving. While LUS is widely available and accurate, there is limited evidence from low- and middle-income countries. We aim to assess LUS's predictive ability for BPD in preterm neonates less than 30 weeks gestation.Material and methodsWe enrolled 160 neonates born at <
30 weeks of gestation, who required any form of respiratory support at least for 24 h. Six zone LUS was calculated for all the neonates first within 72 h and then weekly till 36 weeks of post-menstrual age (PMA) or discharge, whichever was earlier. After excluding death and missed scans, 112 neonates were categorized as BPD or non-BPD and were analysed for their LUS.ResultNeonates who developed BPD (
