Lung sonographic findings in COVID-19 patients

Objective: The objective of this study was to describe the lung sonographic findings of COVID-19 patients prospec-tively and investigate its association with disease severity. Methods: This study was conducted in an emergency department and included consecutively enrolled laboratory confirmed COVID-19 patients. Lung sonography findings were described in all the included patients and analysed with respect to the clinical severity of the patients. Results: 106 patients were included in the study. Common sonographic findings in COVID-19 patients were pleu-ral line irregularity or shredding (70% of patients), followed by B - profile (59%), pleural line thickening (33%), occasional B - lines (26%), sub-pleural consolidations (35%), deep consolidations (6%), spared areas (13%), con-fluent B - lines or waterfall sign (14%) and pleural effusion (9%). These findings tended to be present more bilat-erally and in lower lung zones. Sonographic characteristics like bilateral lung involvement, B - profile, spared areas and confluent B - lines or waterfall sign were significantly associated (p < 0.01) with clinical severity (more frequent with increasing disease severity). Conclusion: The lung sonographic findings of COVID-19 were found more bilaterally and in lower lung zones, and specific findings like B - profile, pleural thickening, spared areas and confluent B - lines or waterfall sign were associated with severe COVID-19.
