【摘要】：目的探讨分析老年脑卒中患者并发肺部感染的病原学及危险因素,为有效降低老年脑卒中患者发生院内肺部感染提供参考。方法选择2006年7月-2013年7月医院收治的急性脑卒中老年患者325例,采用单因素以及多因素logistic回归分析,对可能影响患者并发肺部感染的各因素进行分析。结果 325例患者中,并发肺部感染患者80例,肺部感染率为24.62%;80例合并肺部感染患者共检出病原菌106株,其中革兰阴性菌75株占70.75%、革兰阳性菌24株占22.64%、真菌7株占6.61%;单因素分析结果显示,年龄、卒中类型、合并基础疾病、意识障碍、吞咽障碍、长期吸烟史、侵入性操作、卧床时间≥14d与老年脑卒中患者肺部感染的发生具有相关性(P0.05);logistic回归分析显示,合并基础疾病、年龄大、侵入性操作、卧床时间≥14d及意识障碍为影响老年脑卒中患者肺部感染的独立危险因素。结论合并基础性疾病、高龄、侵入性操作、长期卧床以及合并意识障碍是老年脑卒中患者并发肺部感染的独立危险因素,需要引起临床工作者的重视。
[Abstract]:Objective to investigate the etiology and risk factors of pulmonary infection in elderly stroke patients. To effectively reduce nosocomial pulmonary infection in elderly stroke patients, 325 elderly patients with acute stroke were selected from July 2006 to July 2013. Univariate and multivariate logistic regression analysis was used. Results among 325 patients, 80 cases were complicated with pulmonary infection, and the pulmonary infection rate was 24.62%. 106 strains of pathogenic bacteria were detected in 80 patients with pulmonary infection. Among them, 75 Gram-negative bacteria accounted for 70.75, 24 Gram-positive bacteria accounted for 22.64, and 7 fungi accounted for 6.61.The results of univariate analysis showed that age, stroke type, associated basic diseases, disturbance of consciousness, dysphagia, long-term smoking history, invasive operation, There was a correlation between bed rest time 鈮，
