LUS findings
Table 3 shows main baseline (T0) LUS features of children with mild and
moderate disease. Those who had moderate disease presented more B line
than children with mild disease (85.7% vs 36.4% respectively; p: .03).
Furthermore, in children with moderate disease, pleural irregularity and
subpleural consolidations were more frequently found than in those with
mild forms.
After 96 hours we had observed ultrasound abnormality al the LUS only in
20% of the children. In particular, we found a statistically
significant reduction in pleural irregularities (30% vs 16.7; p:
.001) and in B lines (50% vs 20%; p: .008) as showed in Table
2.
We observed a good LUS accuracy in comparison with other imaging
technique (CXR/CT/MRI) to found lung abnormality (sensitivity of 90.9%
and specificity of 66.6%) (Figure 2).
The inter-rater agreement was .903 with Cohen’s kappa coefficient of
.80.
