The correlation between lung ultrasound score and neonatal critical illness score and its clinical predictive value / 中华超声影像学杂志

ABSTRACT

Objective To explore whether the lung ultrasound( LUS) score can be used to assess and predict the criticality of neonates with pulmonary disease at an early stage . Methods T he new borns born in the obstetrics department of Affiliated Hospital of Jining M edical University from April to October 2018 were transferred to the neonatal intensive care unit due to respiratory distress . T he children underwent LUS examination and scoring at 2 hours after birth . T he correlation analysis were performed between LUS score and neonatal critical illness score ( NCIS ) ,NCIS +single index ,respectively . And the ROC curve was used to analyze the value of LUS score in predicting neonatal criticality . Results ①T he LUS score of non‐critical neonates was significantly lower than that of critically ill newborns , the difference was statistically significant ( P ＝0 .005) ; LUS score was an independent risk factor for critical neonates ( OR＝1 .71 ,95%CI1 .059－2 .765 , P ＝ 0 .028 ) . ② T he correlation coefficient between LUS score and NCIS was －0 .48 ( P ＝0 .002) . T he correlation coefficient between the LUS score and the NCIS + single index was －0 .44 ( P＝0 .005) . ③T he area under the ROC curve of LUS score predicting neonatal criticality was 0 .88 ( 95%CI0 .725－0 .965 , P ＜0 .000 1) ,the optimal diagnostic threshold was 6 points with sensitivity of 80% and specificity of 100% . Conclusions The LUS score at a postnatal age of 2 hours after birth can early assess and predict the criticality of neonates with pulmonary disease . And the LUS score greater than 6 has the highest diagnostic value .
