老年心力衰竭患者发生肺部感染的相关危险因素及防治

Relevant Risk Factors and Prevention and Control of Lung Infection of Senile Heart Failure Patients

目的分析引发老年心力衰竭患者发生肺部感染的相关危险因素以及有效的防治措施。方法方便选择该院自2016年2—12月收治的95例老年心力衰竭患者作为研究对象,回顾性分析患者的临床资料,根据患者肺部感染情况将其分成感染组和未感染组,其中感染组43例,未感染组52例,比较两组患者的各项临床资料和相关治疗指标,以分析引发患者出现肺部感染的相关危险因素,并探究有效的防治措施。结果感染组患者合并慢性阻塞性肺疾病比例(32.5%)明显大于未感染组(3.8%),感染组患者左心室射血分数<35%的比例(48.8%)明显大于未感染组(13.5%),两组对比差异有统计学意义(P<0.05)。结论引发老年心力衰竭患者发生肺部感染的相关危险因素有年龄、吸烟史、长期卧床、抗生素及激素滥用史等,临床治疗过程中需采取针对性的防治措施,才能有效降低患者肺部感染的发生几率。

Objective To analyze the relevant risk factors and effective prevention and control measures of senile heart failure patients. Methods 95 cases of senile heart failure patients admitted and treated in our hospital from February to December 2016 were conveniently selected and divided into two groups according to the lung infection situations, including43 cases in the infection group and 52 cases in the non-infection group, and various clinical data and related treatment indexes were compared between the two groups in order to analyze the related risk factors of lung infection and study the effective prevention and control measures. Results The ratio of chronic obstructive pulmonary disease in the infection group was obviously higher than that in the non-infection group,(32.5% vs 3.8%), and the ratio of patients whose left ventricular ejection fraction <35% in the infectious group was higher than that in the non-infectious group,(48.8% vs 13.5%), and the difference between groups was obvious(P<0.05). Conclusion The related risk factors of lung infection of senile heart failure patients are age, smoking history, long-term bed and abuse of antibiotics and hormone, and we should use the targeted prevention and control measures in the clinical treatment to effectively reduce the occurrence probability of patients.
