Combination of Lung Ultrasound(a Comet-tail Sign) and N-terminal Pro-brain Natriuretic Paptide in Differentiating Acute Dyspnea in Prehospital Emergency Setting

Acute heart failure is one of the main causes of acute respiratory distres in prehospital emergency setting. The early and correct diagnosis is important because the misdiagnosis can result in deleterious consequeance to patients. Rapid bedside tests (like NT-proBNP) and point-of-care lung ultrasound could be useful methods in field. This study confirmed that the combination of ultrasound sign in combination with rapid NT-proBNP test has a hibh diagnostic accuracy in differentiating between cardiac and pulmonray causes of acute dyspnea in the field and the tretament possibilities in clinical obscure cases are mainly improved.
