Abstract: Objective To analyze the diagnostic accuracy rate of lung ultrasound and chest X-ray in neonatal respiratory dysfunction (NRD),as well as the consistency between lung ultrasound score and respiratory score,so as to provide evidence for clinical application of lung ultrasound in NRD. Methods A total of 60 neonates with NRD in NICU of the First Affiliated Hospital of Kunming Medical University were enrolled in this study from August 2018 to January 2019(respiratory dysfunction group),and 30 neonates without respiratory disorder were selected as non-respiratory dysfunction group.All subjects performed lung ultrasound,and pulmonary ultrasound scores.The NRD group underwent chest X-ray examination and received Silverman-Anderson (SA) score and Downes score assesment.All data were analyzed by SPSS 23.0. Results The sensitivity and specificity of the lung ultrasound diagnosis for NRD were 96.7%,the accuracy of lung ultrasound diagnosis was 88.3%,and the accuracy of chest X-ray diagnosis was 83.3%.The two diagnostic methods were moderately consistent(Kappa=0.523,P<0.001).Lung ultrasound score was positively correlated with SA score and Downes score (r_s=0.585,0.533,P<0.001). Conclusions Lung ultrasound and chest X-ray have a good consistency in the diagnosis of NRD.Lung ultrasound has important clinical application value in NRD.
