The method of the lung ultrasound (LUS) has been known for more than 20 years, but attracted attention during the epidemic of COVID-19 infection.
Objectives. To evaluate the possibility of detecting LUS features using a 12-zone protocol in outpatients with pneumonia associated with COVID-19 infection.
Material and methods. We examined 39 outpatients with diagnostic criteria for COVID-19 infection (17 men and 22 women) aged 31-75 years (median 49 years). All patients underwent ultrasound of the lungs immediately after computerized tomography (CT) scan by a blinded specialist. Correlation analysis of the results of the quantitative assessment of the detected changes, as well as the assessment of the diagnostic value of the pulmonary ultrasound method for identifying the signs of pneumonia were performed.
Results. CT diagnosis of pneumonia was found in 25 patients (64%; 95% CI 47-79). Ultrasound signs of interstitial abnormalities were detected in 31 patients. When evaluating the method informativeness, the optimal sensitivity/specificity ratio was obtained for a value of ≥2 points, the area under the curve (AUC) =0.970 (95% CI 0.858-0.999; p<0.0001). The score of the lung ultrasound significantly correlated with the quantitative assessment on CT scan (r=0.928, p<0.001).
Conclusions. Pulmonary ultrasound can be very useful in the conditions of providing primary care, in the conditions of a significant number of admitted patients to detect features of COVID-19 associated pneumonia.
