Study on CT Signs and Diagnostic Value of Severe Pneumonia Complicated with Pulmonary Infection

Objective To study the chest CT signs and diagnostic value of severe pneumonia with pulmonary infection.Methods the clinical data of 60 patients with severe pneumonia complicated with pulmonary infection admitted to our hospital from June 2018 to June 2019 were retrospectively analyzed.According to different examination methods,they were divided into observation groups(n=30)and control groups(n=30).the observation group was given routine laboratory examination combined with chest CT examination,and the control group was given chest X-ray examination.the positive rate of diagnosis of pulmonary infection and different pathogens were compared between the two groups.CT imaging features of pulmonary infection.results the positive rate of diagnosis was 90.00%in the observation group and 53.33%in the control group.there was a significant difference between the two groups(P<0.05).In the observation group,20 patients showed patchy and patchy solid shadows,including 4 with cavity shadows,2 with air bag,4 with blurred lung texture,and ground glass shadows;in the control group,the main manifestations were inflammatory infiltration in the lung,and 3 with cavity shadows.the main pathogens in sputum culture of patients with pulmonary infection were Pseudomonas aeruginosa,Staphylococcus aureus,and Klebsiella pneumoniae.the main manifestations of Pseudomonas aeruginosa pneumonia were local pulmonary consolidation and pulmonary abscess.there were 8 cases and 4 cases of empty shadow in this group.Staphylococcus aureus mainly showed inflammatory infiltration of the lung parenchyma,and most of them showed large dense and blurred shadows,a few showed stage or lobar infiltration,and at the same time,there was a pulmonary balloon.Klebsiella was the main manifestation in 2 patients in this group.the manifestations were lobular infiltration in the posterior segment of upper and lower lobes of both lungs and arc-shaped interlobar fissures in 4 cases.Conclusion thoracic CT can improve the accuracy of early pulmonary infection in patients with severe pneumonia complicated with pulmonary infection,reduce missed diagnosis and misdiagnosis,and is worthy of further clinical promotion.
