重症监护室医院获得性肺炎40例临床分析

目的:探讨重症监护病房(ICU)医院获得性肺炎(HAP)的发病率、病死率、诱发因素、病原菌分布及其耐药性,为医院获得性肺炎的防治提供依据.方法:回顾性分析急诊ICU内40例医院获得性肺炎患者的临床资料.结果:死亡23例,病死率57.5%.常见的诱发因素为气管插管或气管切开87.5%(35/40).病原菌主要是铜绿假单胞菌35%(14/40)和鲍曼氏不动杆菌20%(8/40),且出现多重高比例耐药.结论:ICU医院获得性肺炎病死率高,病原菌以革兰氏阴性杆菌为主,耐药菌株多,应合理选择抗生素.

Clinical analysis on 40 cases of hospital acquired pneumonia in ICU

Objective:To investigate the hospital acquired pneumoma in ICU,including its morbidity rate,mortality rate,including factors,and pathogenic distribution and its drug resistance.Methods:A clinical retrospective analysis was carried out to investigate 40 cases of patients acquiring pneumonia in EICU.Results:Twenty-three of 40 cases (57.5%)died.Factors significantly predisposing hospital acquired pneumonia were tracheal intubations or tracheotomy(35%).Pathogenic bacteria Pseudomonas aeruginosa (35%) and Acinetobacter baumannii (20%) were found in most of 40 cases.And the analysis of drug sensitivity showed resistance among all the agents tested in different levels,also the multidrug resistance emerged.Conclusion:Mortality rate of HAP is found high in ICU.The leading causative microorganisms are Gram-negative bacteria,and drug-resistant bacteria.Antibiotics should be appropriately selected.
