AbstractLung ultrasound (LUS) has shown to be a useful tool to detect the degree of pulmonary involvement in patients with pneumonia and acute respiratory distress syndrome. The present study evaluates the association of the 12-region lung ultrasound score and the requirements of intensive care unit, in patients with COVID-19 infection who were admitted to intermediate care in a specialized hospital; 115 patients with a diagnosis of pneumonia confirmed by chest radiography secondary to SARS-CoV-2 were included, LUS was performed together with the laboratory evaluation that included the measurement of inflammatory biomarkers (lymphocytes, C-reactive protein, D-dimer, procalcitonin, ferritin, lactate dehydrogenase, and pro B-type natriuretic peptide). Lung ultrasound score was used, characterizing the degree of lung involvement as mild, moderate, and severe, and the results were compared with inflammatory biomarkers. In the univariate analysis, an association was observed between the lung ultrasound score, elevated levels of procalcitonin and brain natriuretic peptide, and the admission to intensive care. In the multivariate analysis, only the lung ultrasound score was an independent predictor of need for intensive therapy.
