Materials and Methods
We conducted an observational study analyzing LUS patterns in
consecutively admitted children with COVID-19 infection in a tertiary
level pediatric hospital in Rome from the 27 of March 2020 to June the
1st 2020. All patients with swab-confirmed COVID-19
infection who underwent LUS within 6 hours from admission (T0) and after
96 hours (T1) were included. Patients aged 18 years or more, those who
did not underwent both LUS or with comorbidity were excluded. The
severity of the disease was classified using the classification of Parri
et al, based on the adapted classification of Dong et
al.15,16 The use of LUS in the evaluation of children
with respiratory infection has been approved by the ethics committees of
our institution. Informed consent was obtained from each
parent/guardian.
