This study aimed to determine whether the assessment of lung ultrasound score (LUS) and thoracic fluid contents (TFC) can predict the severity of respiratory distress syndrome (RDS) and the development of bronchopulmonary dysplasia (BPD) in preterm infants. The results showed that LUS and TFC had good predictive ability for the need for mechanical ventilation and the development of BPD. Therefore, the combined evaluation of LUS and TFC by lung ultrasonography and electrical cardiometry may provide a useful predictive tool for short- and medium-term pulmonary outcomes in preterm infants with RDS.
This study aims to evaluate whether the assessment of a lung ultrasound score (LUS) by lung ultrasonography and of thoracic fluid contents (TFC) by electrical cardiometry may predict RDS severity and the development of bronchopulmonary dysplasia (BPD) in preterm infants with respiratory distress (RDS). Infants <= 34 weeks' gestation admitted with RDS to two neonatal intensive care units were prospectively enrolled in this observational study. A simultaneous evaluation of LUS and TFC was performed during the first 72 h. The predictivity of LUS and TFC towards mechanical ventilation (MV) need after 24 h and BPD development was evaluated using receiver operating characteristic analysis. Sixty-four infants were included. The area under the curve (AUC) for the prediction of MV need was 0.851 (95%CI, 0.776-0.925, p < 0.001) for LUS and 0.793 (95%CI, 0.724-0.862, p < 0.001) for TFC, while an AUC of 0.876 (95%CI, 0.807-0.946, p < 0.001) was obtained for combined LUS and TFC evaluation. LUS and TFC AUC for BPD prediction were 0.769 (95%CI, 0.697-0.842, p < 0.001) and 0.836 (95%CI, 0.778-0.894, p < 0.001), respectively, whereas their combined assessment yielded an AUC of 0.867 (95%CI, 0.814-0.919, p < 0.001). LUS >= 11 and TFC >= 40 were identified as cut-off values for MV need prediction, whereas LUS >= 9 and TFC >= 41.4 best predicted BPD development. Conclusion: A combined evaluation of LUS and TFC by lung ultrasonography and EC during the first 72 h may represent a useful predictive tool towards short- and medium-term pulmonary outcomes in preterm infants with RDS.
