血管性痴呆患者并发肺部感染现状及其影响因素研究

Pulmonary infection status of patients with vascular dementia and its influencing factors

目的分析血管性痴呆患者并发肺部感染现状及其影响因素,为该类患者肺部感染的控制提供参考依据。方法选择2014年1月-2016年8月血管性痴呆患者86例为研究对象,对发生肺部感染的进行统计,并比较不同性别、年龄、基础疾病、吸烟史、饮酒史、营养状态、住院时间、免疫状态、抗菌药物应用及侵入性操作等的血管性痴呆患者的肺部感染率,采用logistic回归分析处理上述因素与患者肺部感染的关系。结果 86例患者中肺部感染15例,感染率为17.44%,其中女性、年龄较高、并发基础疾病、有吸烟史、有饮酒史、营养状态较差、住院时间较长、免疫状态较差、未应用抗菌药物及进行侵入性操作治疗患者的肺部感染率明显高于男性、年龄较低、无基础疾病、无吸烟史、无饮酒史、营养状态较好、住院时间较短、免疫状态较好、应用抗菌药物及未进行侵入性操作的患者,经logistic回归分析显示,上述因素均是肺部感染的危险因素(P<0.05)。结论血管性痴呆患者的肺部感染率较高,且其发生的影响因素较多,因此应根据患者自身情况给予针对性的预防与治疗。

OBJECTIVE To analyze the pulmonary infection status of patients with vascular dementia and its influencing factors,so as to provide evidence for the control of pulmonary infection of these patients.METHODS A total of 86 patients with vascular dementia in our hospital from Jan.2014 to Aug.2016 were selected as the research objects,and the pulmonary infection rate was analyzed.The pulmonary infection rates of patients with different genders,ages,underlying diseases,smoking history,drinking history,nutritional state,hospitalization time, immune state,antibiotic application situation and invasive procedure situation were compared,and the relationship between those factors and pulmonary infection of these patients were analyzed by logistic regression analysis.RESULTS Totally 15 cases of 86 patients were with pulmonary infection,and the pulmonary infection rate was 17.44%.The pulmonary infection rates of patients of female,older age,combined underlying disease,smoking history,drinking history,worse nutritional state,longer hospitalization time,worse immune state,no antibiotic application and invasive procedure were all higher than the rates of patients of male,younger age,without underlying disease,without smoking history,without drinking history,better nutritional state,shorter hospitalization time,better immune state,antibiotic application and without invasive procedure.Logistic regression analysis showed that those factors were all risk factors of pulmonary infection（P〈0.05）.CONCLUSION The pulmonary infection rate of patients with vascular dementia is high,and there are many influencing factors,so the patients should be given targeted prevention and treatment according to thc personnel situation of patients.
