老年冠心病合并心力衰竭患者医院肺部感染的危险因素及预防对策

Risk factors and preventive measures for nosocomial pulmonary infection in elderly patients with coronary heart disease and heart failure

目的 分析老年冠心病合并心力衰竭患者医院肺部感染危险因素。方法 收集老年冠心病合并心力衰竭患者166例作为研究对象,按照是否出现肺部感染情况将其分为研究组(有肺部感染)86例和对照组(无肺部感染)80例,分析老年冠心病合并心力衰竭医院肺部感染的危险因素。结果 住院时间、慢性阻塞性肺疾病史、糖尿病史、吸烟史、侵入性操作以及卧床在两组中差异有统计学意义(P<0.01),慢性阻塞性肺疾病史、糖尿病史、卧床为老年冠心病合并心力衰竭患者出现医院肺部感染的独立危险因素。结论 在临床治疗过程中要重视对老年冠心病合并心力衰竭患者的高危因素进行积极治疗及控制,以便有效降低患者肺部感染发生几率。

Objective To analyze the risk factors and preventive measures for nosocomial pulmonary infection in elderly patients with coronary heart disease and heart failure.Methods A total of 166 elderly patients with coronary heart disease and heart failure were selected as the research objects and divided into the Study Group(with pulmonary infection,86 cases)and the Control Group(without pulmonary infection,80 cases)according to whether there was pulmonary infection to analyze the risk factors of nosocomial pulmonary infection in elderly patients with coronary heart disease and heart failure.Results There were significant differences in hospital stay,history of chronic obstructive pulmonary disease,history of diabetes,smoking history,invasive operation and bed rest between the two groups(P<0.01).History of chronic obstructive pulmonary disease,history of diabetes and bed rest were independent risk factors for nosocomial pulmonary infection in elderly patients with coronary heart disease and heart failure.Conclusion In the process of clinical treatment,attention should be paid to active treatment and control of high-risk factors in elderly patients with coronary heart disease and heart failure,so as to effectively reduce the incidence of pulmonary infection in patients.
