ultrasonography has shown a growing interest during the last few years
based on its new applications and significance of sonographic artifacts.
assess the ability of bedside chest ultrasonography (USG) in prognosis
of Community-acquired pneumonia (CAP) patients and to compare with
Pneumonia severity index (PSI) score & chest radiograph(CXR ).
prospective observational study in 100 patients who got admitted with
CAP, PSI scoring was determined and CXR &USG done at the time
of presentation.PSI scoring, CXR & USG repeated on third day
and at the time of final outcome.
Results: USG showed
features of consolidation in 92% patients. Dynamic air bronchogram was
present in patients with sonographically detected pneumonia.
Hepatisation of lung tissue detected in 30% and irregular &
serrated margins in 43% of patients. Pleural effusion was evident in
29% of patients by USG, but only 13% by CXR. Disease remission was also
demonstrated sonographically. The proportion of patients with an air
bronchogram decreased to 39% of patients during discharge.Correlation
between USG, CXR and PSI score were analysed using Spearman's rho rank
correlation (r). A significant correlation between USG and PSI score
was found (on day1 r= 0.35, on day3 r= 0.43, & on final day r=
0.25) which were significant at 0.01 level. A significant correlation
was also found between USG and CXR (on day1 r=0.81, on day3 r=0.81
& on final day r=0.74) which were significant at 0.01 level.
study supports the routine use of chest-ultrasound in prognostic
evaluation of CAP, as it is bedside real time, reliable, rapid,
non-invasive technique and it help for rapid therapeutic decision.
