Abstract:
Objective To propose a modified lung ultrasound score(LUS),and to observe its value for evaluation on severity of acute respiratory distress syndrome(ARDS).Methods Data of lung ultrasound,chest X-ray and so on in 33 sudden ARDS patients were retrospectively analyzed.The patients were divided into moderate-severe group(n=16)and mild group(n=17)according to oxygenation index(OI).The outcomes of LUS,modified LUS and radiographic assessment of lung edema(RALE)score were compared between groups.Receiver operating characteristic(ROC)curves were drawn,the area under the curves(AUC)were calculated to evaluate the efficacy of various image scores for evaluating the severity of ARDS.Pearson correlation analysis was performed to explore the correlations of various image scores with OI,of RALE score with LUS and modified LUS in ARDS patients.Results LUS and modified LUS in moderate-severe group were both higher than those in mild group(both P＜0.05).No significant difference of RALE score was found between groups(P＞0.05).AUC of LUS,modified LUS and RALE score for evaluating the severity of ARDS was 0.809,0.853 and 0.640,respectively.LUS and modified LUS in ARDS patients were moderately negatively correlated with OI(r=-0.570,P=0.001;r=-0.708,P＜0.001),while no obvious correlation of RALE score and OI was found(r=-0.229,P=0.201).RALE score of ARDS patients was moderately positively correlated with both LUS and modified LUS(r=0.588,P＜0.001;r=0.502,P=0.003).Conclusion The above mentioned modified LUS could effectively evaluate severity of ARDS,with better efficacy than LUS and RALE score.
