摘要
目的探讨医院感染病原菌的临床分布特点及耐药现状,为临床用药提供参考。方法对2004-2006年住院患者发生医院感染的病原菌及耐药情况进行回顾性分析。结果3年来所有发生医院感染的病例中共分离出488株病原菌,革兰阴性菌289株,占59.22%;革兰阳性菌95株,占19.47%;真菌104株,占21.31%;真菌、鲍氏不动杆菌、阴沟肠杆菌这3种菌的分离率逐年上升;这些菌株对临床常用抗菌药物均有不同程度的耐药,多药耐药率80.33%。结论医院感染病原菌以革兰阴性菌为主导,对常用的抗菌药物耐药率较高,而且呈多药耐药趋势,应引起重视;临床应尽量减少医院感染的易感因素,重视病原菌培养,合理使用抗菌药物,降低医院感染发生率。
OBJECTIVE To explore the clinical distributed features and drug-resistant conditions of pathogenic bacteria in nosocomial infection in the last three years for the reference to clinical drug administration. METHODS Retrospective analysis was performed about drug-resistant conditions of pathogenic bacteria in nosocomial infection in the last three years from 2004 to 2006. RESULTS Totally 488 pathogenic stralns, including 289 strains of Gramnegative bacteria （59.22%） ;95 strains of Gram-positive bacteria （19.47%） and 104 strains of fungi （21.31%）, were isolated from patients in the last three years, the isolation rate of fungi,Acinetobacter baumannii and Enterobacter cloacae tended to increase year by year. They resisted to commonly used antibiotics at different degree, the rate of multiple-resistance was 80.33%. CONCLUSIONS Most pathogens isolated from patients with nosocomial infection are Gram-negative bacteria, which always display multi-resistant tendency to routine antimicrobial agents. The culture of pathogenic bacteria and rational use of antimicrobial agents should be emphasized to decrease the incidence of nosocomial infection, the factors which easily caused nosocomial infection should be reduced as well.
