Diagnostic value of lung ultrasound in evaluating the severity of neonatal respiratory distress syndrome

Abstract Background It is still unclear whether lung ultrasound (LUS) can be used to evaluate the severity of neonatal respiratory distress syndrome (NRDS). Objective To evaluate the role of LUS in assessing NRDS. Methods From January 2017 to January 2018, newborns with suspected NRDS were enrolled. The LUS score and lung consolidation areas were determined. The receiver operative curve (ROC) was used to analyze the LUS score and lung consolidation to predict NRDS severity. Results Neonates with NRDS had higher LUS scores than those with non-NRDS (23.6 ± 3.6 vs. 16.2 ± 1.8, P   0.05). Conclusion The LUS score and consolidation areas can discriminate NRDS from non-NRDS and the different grades of NRDS, and predict the application of mechanical ventilation.
