【摘要】：目的探讨急诊ICU老年患者肺部感染的临床特点及相关危险因素,并针对高危因素分析其预防对策。方法选取2013年2月-2016年2月医院急诊ICU收治的老年患者866例,研究老年患者肺部感染的临床特征及感染病原菌分布,采用单因素与多因素分析导致ICU老年患者肺部感染的高危因素,并进行统计学检验。结果肺部感染患者的主要临床表现是咳嗽咳痰、胸闷气促,其中98.88%的患者X线检查发现阳性征象,痰培养结果显示,肺炎克雷伯菌和铜绿假单胞菌构成比相对较高,分别占39.32%和30.34%;单因素分析结果显示,年龄、基础疾病、侵入性操作与老年患者肺部感染的发生具有相关性(P0.05);多因素logistic回归分析结果显示,年龄≥80岁、基础疾病≥2种、有侵入性操作是导致肺部感染的独立危险因素;89例肺部感染患者经过治疗,其中48例(53.93%)患者症状完全消失,17例(19.10%)患者症状缓解,18例(20.22%)患者病情恶化,6例(6.74%)患者死亡。结论 ICU老年患者肺部感染的高危因素包括年龄≥80岁、有≥2种基础疾病以及侵入性操作,针对以上高危因素制定预防措施对于减少肺部感染具有积极作用。
[Abstract]:Objective to investigate the clinical characteristics and related risk factors of pulmonary infection in elderly patients with emergency ICU, and to analyze the preventive measures against the risk factors. Methods 866 elderly patients with emergency ICU were selected from February 2013 to February 2016 in our hospital. To study the clinical characteristics and pathogenic bacteria distribution of pulmonary infection in elderly patients, univariate and multivariate analysis was used to analyze the high risk factors of pulmonary infection in elderly patients with ICU. Results the main clinical manifestations of patients with pulmonary infection were cough and sputum, chest tightness and shortness of breath. Among them, 98.88% of the patients found positive signs by X-ray examination, and the results of sputum culture showed that, The composition ratios of Klebsiella pneumoniae and Pseudomonas aeruginosa were relatively high, accounting for 39.32% and 30.34 respectively. There was a correlation between invasive operation and pulmonary infection in elderly patients (P 0.05). The results of multivariate logistic regression analysis showed that age 鈮，
