Kong S, Wang J, Li Y, et al. - Whether bedside lung ultrasound (LUS) affords a valuable tool for patients with severe and critical coronavirus disease 2019 (COVID-19)-associated lung injury, was inquired in this study. Participants were 63 severe and 33 critical hospitalized people with COVID-19. All patients underwent examination via bedside LUS; chest computed tomography was carried out on the same day as bedside LUS in 23 cases. In the critical COVID-19 group, there was a higher proportion of bilateral or unilateral lung consolidation and pleural effusion when compared with that in the severe group. Among participants with severe and critical COVID-19 pneumonia, the identified most common abnormal LUS pattern was B-lines, followed by lung consolidation. Higher median (interquartile range) LUS scores were seen in critical cases vs those of severe cases. A good correlation was evident between the LUS score and the chest computed tomography score. Overall, findings indicate the utility of bedside LUS in offering crucial information for lung involvement in patients suffering from COVID-19.
