Analysis of the Main Pathogenic Types and Risk Factors of Community Acquired Pneumonia Complicated with Pleural Effusion/Empyema
Objective To study and analyze the main pathogenic types and related risk factors of empyema.Method Hospitalized patients with pneumonia complicated by pleural effusion in our facility were the subjects of a retrospective analysis(control group and case group).Pathogenic analysis was conducted on the pus culture results of the case group.By comparing the clinical data characteristics of the two groups of patients,the risk factors of pneumonia induced empyema were analyzed,in order to intervene in the development of severe lung infection into empyema and reduce mortality.Results In the univariate analysis,the nutritional status,length of hospitalization,diabetes,alcoholism,etc.of the two groups were P＜0.05,which were the risk factors of pneumonia complicated with empyema.In the logistic regression analysis,the history of diabetes,alcoholism,adequate drainage of pleural effusion,high or low white blood cell count,C-reactive protein size,platelet size,and serum albumin level were independent risk factors for pneumonia empyema.Gram negative bacteria had a high incidence of Escherichia coli(11.67％),while Gram positive bacteria had a higher infection rate of Streptococcus viridis(23.33％),according to the results of bacterial culture in pus.Conclusion The risk factors for pneumonia combined with empyema are multifaceted.Clinical physicians should detect serious complications from pulmonary infections as soon as possible,treat them with closed thoracic drainage intervention and sensitive antibiotics to improve clinical efficacy and prognosis,and prevent pneumonia from progressing to complex pleural effusion/empyema.
