【摘要】：目的了解高血壓性腦出血患者術(shù)后下呼吸道感染的病原菌分布特征,并分析引發(fā)下呼吸道感染的相關(guān)危險(xiǎn)因素。方法對(duì)2015年8月-2016年8月醫(yī)院1000例高血壓性腦出血患者術(shù)后臨床資料進(jìn)行回顧性分析,對(duì)醫(yī)院感染率、病原菌分布特征、下呼吸道感染的危險(xiǎn)因素進(jìn)行分析。結(jié)果 1 000例高血壓性腦出血患者術(shù)后發(fā)生下呼吸道感染143例,感染率為14.30%;143例下呼吸道感染患者中,83例痰培養(yǎng)陽性,陽性率為58.04%;共分離出病原菌224株,其中革蘭陰性菌142株占63.39%,革蘭陽性菌48株占21.43%,真菌34株占15.18%;單因素分析顯示,年齡≥65歲、有侵入性診療、住院時(shí)間14d、血糖水平7.8mmol/L、合并基礎(chǔ)性疾病者下呼吸道感染率明顯高于年齡65歲、無侵入性診療、住院時(shí)間≤14d、血糖水平≤7.8mmol/L、無基礎(chǔ)性疾病者,差異有統(tǒng)計(jì)學(xué)意義(P0.05);年齡、侵入性診療、住院時(shí)間、血糖水平、基礎(chǔ)性疾病是高血壓性腦出血患者術(shù)后下呼吸道感染獨(dú)立危險(xiǎn)因素。結(jié)論高血壓性腦出血患者術(shù)后下呼吸道感染率較高,以革蘭陰性菌感染為主,應(yīng)加強(qiáng)抗菌藥物的合理應(yīng)用,針對(duì)其相關(guān)因素進(jìn)行預(yù)防,對(duì)降低下呼吸道感染具有重要作用。
[Abstract]:Objective to investigate the distribution of pathogens of lower respiratory tract infection in patients with hypertensive intracerebral hemorrhage after operation, and to analyze the risk factors of lower respiratory tract infection. Methods the clinical data of 1000 patients with hypertensive intracerebral hemorrhage from August 2015 to August 2016 were retrospectively analyzed. The nosocomial infection rate, the distribution of pathogenic bacteria and the risk factors of lower respiratory tract infection were analyzed. Results 143 cases of lower respiratory tract infection occurred in 1 000 patients with hypertensive intracerebral hemorrhage, the infection rate was 14.30% and 143 cases of lower respiratory tract infection, 83 cases were positive in sputum culture, the positive rate was 58.04, 224 strains of pathogenic bacteria were isolated. Among them, 142 strains of Gram-negative bacteria accounted for 63.39%, 48 strains of Gram-positive bacteria accounted for 21.43 and 34 strains of fungi accounted for 15.18.The univariate analysis showed that the age 鈮，
