The Significance of Lung Ultrasonography in Children with COVID-19

Introduction: The infection of new Coronavirus disease-2019 (COVID-19) continues to affect both adults and children worldwide. Although there are studies of adult patients with COVID-19 that defined ultrasound findings, there is limited data available on the diagnostic use of ultrasonography in children. This study is aimed to evaluate the results of bedside lung ultrasonography (LUS) performed in pediatric patients with COVID-19.Methods: The study included pediatric patients who were diagnosed with COVID-19. All lung areas were visualized on LUS and evaluated together with demographic, clinical, and laboratory data, and chest X-ray (CXR) findings.Results: An evaluation was made of 102 pediatric patients, comprising 54 girls and 48 boys with a mean age of 9.65 +/- 4.78 (min 35 days-max 17) years. Forty-six percent of the patients had respiratory system symptoms, 36% were asymptomatic, and 18% had symptoms other than in the respiratory system. Pathologic findings were determined on CXR in 36% of patients, and on LUS in 57%. The difference in the detection rate of pathologic findings between LUS and CXR was statistically significant (p=0.001). Pathology was observed on LUS in 29 of 65 patients with normal CXR. The sensitivity rate for detecting pathology in patients with respiratory symptoms was 49% on CXR and 77% on LUS (p=0.001).Conclusion: We determined that the sensitivity of LUS is higher than CXR in demonstrating lung involvement in patients with COVID-19 with respiratory symptoms. LUS may be helpful in the evaluation of pediatric patients with COVID-19 but more studies are needed to prove its feasibility in children.
