目的研究呼吸机相关肺炎的致病菌、药敏情况和经验性用药的治疗方法。方法回顾性分析2009年3月-2012年3月在我院接受治疗的30例呼吸机相关肺炎患者的致病菌分类情况及治疗情况。结果该病的病原菌分为两大类,革兰阴性菌占3/4,革兰阳性菌占1/4,其中又以铜绿假单胞菌居多,乙酸钙/鲍曼不动杆菌次之,但混合感染者已超过半数,真菌感染也不少见。结论该病主要为革兰阴性菌感染,临床上应该把如何正确选用合理的抗感染药物放在首位,同时对病原菌的诊断及其耐药性进行分析。
Objective To study the pathogens, drug sensitivity and experience of ventilator-associated pneumonia. Methods A retrospective analysis of 30 cases of ventilator-associated pneumonia in our hospital from March 2009 to March 2012 in patients with pathogenic bacteria classification and treatment. Results The pathogens of the disease were divided into two categories, Gram-negative bacteria accounted for 3/4, Gram-positive bacteria accounted for 1/4, of which Pseudomonas aeruginosa is the majority, followed by calcium acetate / Acinetobacter baumannii, However, mixed infections have more than half of fungal infections are not uncommon. Conclusion The disease is mainly Gram-negative bacteria infection, the clinical should be how to correctly select the appropriate anti-infective drugs in the first place, while the diagnosis of pathogenic bacteria and its resistance analysis.
