Abstract:
Objective To compare the accuracy of bedside lung ultrasound in emergency(BLUE)and combined cardiac-lung and additional ultrasound(CLAUS)for diagnosing the causes of acute dyspnea.Methods Totally 1 016 patients with acute dyspnea were retrospectively enrolled and divided into cardiogenic pulmonary edema group(n=268),pneumonia group(n=574),pneumothorax group(n=33),pulmonary embolism group(n=67)and CAD(chronic obstructive pulmonary disease/asthma/diaphragmatic dysfunction)group(n=74)according to the causes of acute dyspnea.The findings of CLAUS protocol were compared among groups,and the accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea were also compared.Results CLAUS showed that B-B and B-C were the most common modes in cardiogenic pulmonary edema group,while A-B/A-C/B-A/B-B/B-C/C-C modes were common in pneumonia group,and A-A mode was the most common in pneumothorax group,pulmonary embolism group and CAD group.Significant differences of the manifestations of pulmonary ultrasound,pleural feature of anterior chest wall,left/right cardiac insufficiency and abnormal inferior vena cava diameter were found among groups(all P＜0.05).The accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea was 86.91%(883/1 016)and 94.49%(960/1 016),respectively,the latter was higher than the former(χ2=34.587,P＜0.05).Conclusion CLAUS protocol could be used to effectively diagnose the causes of acute dyspnea,with higher accuracy than BLUE protocol.
