3.2 Lung ultrasound scores (LUS) (Figure 3)
In both the groups the LUS score increased from baseline to PSV and but
continued to be increased into post-extubation period in group 1(score 1
vs 2; p-value 0.024); whereas they decreased in-group 2 in the
post-extubation period (score 1 vs 1). There was no significant
difference between the LUS scores between the two groups at the three
time points. Similarly , the total number of B-lines increased from
baseline to PSV in both the groups , but after extubation decreased
significantly in group-2 (B lines 12 vs 9), but continued to increase in
group-1(B lines 9 vs 19).
