Analysis of pathogenic bacteria characteristics and risk factors of pulmonary infection in elderly patients after cerebral infarction
Objective To explore pathogenic bacteria characteristics and risk factors of pulmonary infection in elderly pa-tients after cerebral infarction.Methods The clinical data of 310 elderly patients with cerebral infarction who were treated in Second Affiliated Hospital of Wannan Medical College from January 2020 to December 2023 were retrospectively analyzed.They were divided into observation group(with secondary pulmonary infection)and control group(without secondary pulmonary in-fection)according to whether they had secondary pulmonary infection.The number of patients with pulmonary infection in 310 patients with cerebral infarction was counted and the characteristics of pathogenic bacteria were analyzed.Univariate analysis was conducted on clinical data of the two groups,and the statistically significant indicators were included in the binary Logistic regres-sion analysis to identify the risk factors for pulmonary infection in elderly patients with cerebral infarction.Results Among 310 patients with cerebral infarction,87 cases who suffered from pulmonary infection were set as the observation group,and the re-maining 223 ones were set as the control group.101 strains of pathogenic bacteria were isolated from 87 patients with pulmonary infections,of which 69 ones were Gram-negative,accounting for 68.32% .Univariate analysis and binary Logistic regression analysis found that smoking history,previous history of pulmonary diseases,diabetes,invasive operation,posterior circulation in-farction,severe infarction and swallowing dysfunction were independent risk factors for pulmonary infection in the elderly patients after cerebral infarction.Conclusion The pulmonary infection in the elderly patients after cerebral infarction may be mainly caused by Gram-negative bacteria,and it is related to smoking history,previous history of pulmonary disease,diabetes,invasive operation,infarction degree and swallowing function.Therefore,clinical intervention measures should be taken in time.
