Relationship between chest MSCT signs of patients with pulmonary infection and severity of infection
OBJECTIVE To analyze the relationship between chest multilayer spiral computed tomography(MSCT)signs of the patients with pulmonary infection and severity of the infection.METHODS A total of 312 patients with pulmonary infection who were treated in the Affiliated People's Hospital of Shandong First Medical University from Jan 2020 to Aug 2023 were enrolled in the study,25 of whom were viral infection,51 were fungal infection,124 were non-specific bacterial infection,and 112 were mixed infections.The distribution of MSCT signs was ob-served,the clinical pulmonary infection score(CPIS)and acute physiology and chronic health evaluation Ⅱ(A-PACHE Ⅱ)score were compared among the patients with different MSCT image signs,and the features of MSCT signs were observed and compared among the patients with the pulmonary infections caused by different patho-gens.RESULTS Among the 312 patients with pulmonary infection,53.85％had multiple pulmonary lobes in-volved,and 48.40％presented lung consolidation as abnormal manifestation.The CPIS and APACHE Ⅱ score of the patients with multiple lobes of pulmonary infection were higher than those of the patients with single lobe of pulmonary infection(P＜0.05).The CPIS and APACHEⅡ score of the patients with patch shadow pulmonary infection were higher than those of the patients with lung consolidation,ground-glass change pulmonary infection(P＜0.05);the CPIS and APACHE Ⅱ score of the patients with lung consolidation pulmonary infection were higher than those of the patients with ground-glass change pulmonary infection(P＜0.05).The patients with single lung lobe involved accounted for 56.00％among the patients with viral infection;while the patients with multiple lobes involved ac-counted for 56.86％among the patients with fungal infection,53.23％among the patients with non-specific bac-terial infection,55.36％among the patients with mixed infections.Among the patients with abnormal manifesta-tions,the patients with ground-glass change accounted for 52.00％among the patients with viral infection,41.018％among the patients with fungal infection,38.89％among the patients with mixed infections;the pa-tients with lung consolidation accounted for 79.03％among the patients with non-specific bacterial infection.CONCLUSION MSCT may facilitate the display of scope of infection and abnormal change of the patients with pul-monary infection.The MSCT signs are associated with the severity of infection and can help to determine the type of infection.
