院内肺炎(NP)在医院各科室医院内感染中发病率和死亡率均最高,本文报告220例院内肺炎的病原菌分布及危险因素分析,病原菌中革兰氏阴性细菌占47.2％,革兰氏阳性细菌占38.2％,白色念珠菌14.6％,列前5位病原菌依次为金黄色葡萄球菌15.3％,白色念珠菌14.6％,绿脓杆菌和链球菌各为11.8％,克雷伯杆菌为8.3％,危险因素中年龄、住院天数、慢性阻塞性肺病、脑血管意外、恶性肿瘤、广谱抗生素的应用是主要危险因素、重视这些危险因素是降低院内肺炎的关键。
Nosocomial pneumonia (NP) has the highest morbidity and mortality rate among nosocomial infections in various departments of the hospital. In this paper, the distribution and risk factors of pathogenic bacteria in 220 hospital nosocomial pneumonia were reported. Gram-negative bacteria in pathogens accounted for 47.2%, Gram-positive Bacteria accounted for 38.2%, Candida albicans 14.6%, the top five pathogenic bacteria followed by Staphylococcus aureus 15.3%, Candida albicans 14.6%, Pseudomonas and Streptococcus each 11.8%, Klebsiella was 8.3% Risk factors in age, length of stay, chronic obstructive pulmonary disease, cerebrovascular accident, malignant tumor, the application of broad-spectrum antibiotics is the main risk factors, attention to these risk factors is to reduce the key to nosocomial pneumonia.
