目的 提高临床对嗜麦芽窄食单胞菌(S.m )感染的诊治水平。方法 调查近两年医院血培养证实的S.m感染病例,分析其发病的危险因素、临床特点及对抗菌药物的耐药情况。结果 发现8 例患者均为医院感染,慢性基础疾病及创伤性操作为其易感因素。感染的临床表现多种多样,且对目前常用抗菌药物多有不同程度耐药。结论 有易感因素时,应密切注意S.m 感染的产生,及早进行微生物学检查,尽早根据药敏应用抗菌药物经验性治疗
Objective To improve the clinical diagnosis and treatment of Stenotrophomonas maltophilia (S.m) infection. Methods To investigate the S. pneumoniae confirmed by blood culture in hospital in recent two years and to analyze its risk factors, clinical features and drug resistance to antibiotics. The results showed that all 8 patients were nosocomial infections, chronic underlying diseases and traumatic operations as the predisposing factors. Clinical manifestations of infection varied, and the current commonly used antimicrobial drugs have varying degrees of resistance. Conclusions In the presence of predisposing factors, close attention should be paid to the occurrence of S.m infection. Microbiological examination should be conducted as soon as possible and the empirical treatment of antimicrobial agents should be applied as soon as possible based on drug susceptibility
