Abstract

Objective

The objective of this study was to evaluate computed tomography (CT) findings in patients with sepsis with unknown inflammatory focus and acute respiratory distress syndrome.

Methods

Acute respiratory distress syndrome findings on CT of 36 patients with sepsis were graded on a 6-point scale, and the percentage of affected lung was estimated. Resulting CT scores were correlated to intensive care scores and survival.

Results

Forty-four percent of the patients died, revealing a significantly higher CT score than survivors (P = 0.01). Survivors showed larger areas of unaffected lung (P < 0.001), whereas patients with fatal outcome had more ground-glass opacities (P = 0.002; sensitivity, 73%; specificity, 57%) and traction bronchiectasis (P = 0.009; sensitivity, 54%; specificity, 68%). Pulmonary findings on CT did not allow discriminating between a pulmonary and extrapulmonary focus. No significant coherence between CT score and intensive care scores could be revealed.

Conclusions

A CT scoring system based on pulmonary findings in patients with sepsis with acute respiratory distress syndrome comprises prognostic implications in terms of the patients’ survival.
