Clinical analysis in risk factors of stroke-associated pneumonia in patients with acute cerebral infraction

Abstract

Objective To analyze the risk factors of stroke-associated pneumonia(SAP) in patients with acute cerebral infraction. For reducing the morbidity of SAP. Methods Collected case data of 380 inpatients with acute cerebral infraction in our department from January 2012 to June 2016. The patients were divided into two groups, 69 patients complicated with SAP were served as case group, and 311 patients did not complicated with SAP were served as control group. To analyze the risk factors of SAP after comparing the differences of case data between the two groups. Results The morbidity of SAP was 18.15% (69/380)in patients with acute cerebral infraction. Single factor analysis the clinical characteristics of two groups, the risk factors associated with SAP including age equal or over 65 years, disturbance of consciousness, dysphagia, lie in bed, diabetes mellitus, chronic bronchitis. The difference was statistically significant (P<0.05). OR value from high to low order: disturbance of consciousness, dysphagia, chronic bronchitis, diabetes mellitus, age equal or over 65 years, lie in bed. Multivariate unconditional logistic regression analyses, the result showed above the reasons are independent risk factors for SAP. Conclusion There were many reliated risk factors causing SAP. To control and improve these factors, SAP in patient with acute cerebral infraction could be prevented or cured, and the morbidity would be reduced.
