Clinical severity is associated with different risk factors; however, no clinical, laboratory or radiological factor are able to predict the course of the disease in full term baby. LUS is a good method for the diagnosis and evaluation of pediatric respiratory diseases.Aims: Aim of our study is to evaluate the usefulness of ultrasonography in patients with bronchiolitis, correlating a LUS score with a clinical one, and to compare LUS findings with chest X ray (CXR).Methods: We conducted a prospective longitudinal study and enrolled 92 infants, 63 hospitalized with acute bronchiolitis and 29 for control group. All patients underwent a clinical evaluation with assignment of a clinical severity score and lung ultrasound with assigned a LUS score. Twenty-three out of 63 underwent also a CXR for clinical indications.Results: In patients with bronchiolitis the LUS score correlated with the clinical score (r = 0.62, p<0.001), with hospitalization duration (r = 0.42; p<0.001) and with the need for oxygen therapy (r = 0.59; p<0.001). Furthermore, in patients who performed both LUS and CXR, we found a correlation between the presence of a granularity of the pleural line with LUS and the presence of air trapping with CXR (r = 0.55; p = 0.007).Conclusion: Our study showed that LUS can be used to assess the severity of infants with bronchiolitis.FootnotesCite this article as: European Respiratory Journal 2020; 56: Suppl. 64, 5291.This abstract was presented at the 2020 ERS International Congress, in session “Respiratory viruses in the "pre COVID-19" era”.This is an ERS International Congress abstract.
