The Diagnostic Value of Bedside Cardiopulmonary Ultrasound to Identifying Acute Dyspnea Due to Pulmonary Edema or Pneumonia
[Objective]To evaluate the value of bedside cardiopulmonary ultrasound in differential diagnosis of acute dyspnea caused by pulmonary edema or pneumonia.[Methods]A total of 152 patients with acute dyspnea treated in our hospital from June 2021 to June 2023 were selected,and chest CT was used as the diagnostic gold standard.Among them,68 patients had acute dyspnea due to pulmonary edema and 84 patients had acute dyspnea due to pneumonia.Routine examination and bedside cardiopulmonary ultrasound were performed for all patients.The detection results of routine examination and bedside cardiopulmonary ultrasound for acute dyspnea caused by pulmonary edema or pneumonia were collected.Kappa test was used to analyze the consistency of routine examina-tion,bedside cardiopulmonary ultrasound and chest CT diagnosis,and the differential diagnosis value of routine examination and bedside cardiopulmonary ultrasound for acute dyspnea caused by pulmonary edema or pneumonia was compared.[Results]There was no significant difference in the cost of between routine examination and bedside cardiopulmonary ultrasound(P>0.05),and the time of bedside cardiopulmonary ultrasound was significantly shorter than that of routine examination(P<0.05).The total coincidence rate of bedside cardiopulmonary ultra-sound in diagnosing acute dyspnea caused by pulmonary edema or pneumonia was 84.21%,which was higher than that of routine examination(75.00%)(X2=3.971,P=0.046).Furthermore,Kappa consistency test showed that Kappa=0.625 and 0.731.The AUC for differential diagnosis of acute dyspnea caused by pulmonary edema or pneumonia with routine examination and bedside cardiopulmonary ultrasound was 0.709 and 0.805,respectively.The AUC for differential diagnosis of acute dyspnea caused by pulmonary edema or pneumonia in combination of both routine examination and bedside cardiopulmonary ultrasound was 0.923.[Conclusion]Bedside cardiopulmo-nary ultrasound has a certain diagnostic value in the differential diagnosis of acute dyspnea caused by pulmonary e-dema or pneumonia,among which routine examination combined with bedside cardiopulmonary ultrasound has a higher value in the differential diagnosis of acute dyspnea caused by pulmonary edema or pneumonia.
