ABSTRACT

Objective: To evaluate the diagnostic utility of pulmonary ultrasound in the initial assessment of patients with dyspnea. Material and methods: An observational, descriptive, analytical and cross-sectional study was performed in the Central Military Hospital with patients who presented some degree of dyspnea in the period from February 01 to August 31, 2016. Pulmonary ultrasound was performed as part of their initial assessment regardless of the cause of hospitalization and compared with the definitive diagnosis upon discharge. Results: Thirty-five patients with dyspnea were enrolled in the study and an association between the ultrasonographic pattern and the definitive diagnosis was found, with a sensitivity of 100%, specificity of 88.46%, VPP 75% and VPN 88.46%. Ultrasonographic diagnoses were correlated with the definitive diagnoses χ2 = 43.78, p = 0.002, and had a strong correlation when presenting a contingency coefficient of 0.744 p = 0.002. Conclusions: Pulmonary ultrasound allows an immediate orientation to identify the origin of dyspnea in pleuropulmonary diseases, with an advantage in infectious processes and pleural pathology. In addition to the clinical history, it may be useful to differentiate obstructive causes such as COPD and asthma.
