儿童嗜麦芽窄食单胞菌感染特点及耐药性分析

Antibiotic resistance and infective charsacteristics of Stenotrophomonas maltophilia infection in children

目的分析该地区儿童嗜麦芽窄食单胞菌(SMA)感染的特点及菌株的耐药性,为临床治疗和预防该菌感染提供依据。方法统计分析2011年9月至2012年9月52例入住该院的SMA培养阳性患儿临床资料,并分析其抗菌药物敏感性试验结果。结果临床资料分析显示患儿感染SMA在年龄及性别上并无区别,在检出科室中以新生儿重症监护科(NICU)和儿童重症监护科(PICU)为主,有82.7%的感染SMA患儿都有侵入操作史,有95.92%的SMA患儿有碳青霉烯类药物使用史,感染SMA患儿住院时间较长,平均为(22.3±19.0)d;实验室资料分析显示SMA主要检出标本类型为痰液,占63.5%,4种临床常用药物耐药性较高,磺胺类药物最高达到21.9%。结论儿童SMA感染与碳青霉烯类药物使用及侵入性操作密切相关,耐药情况严重,合理使用抗菌药物成为治疗关键。

Objective To provide the basis for clinical treatment and prevention of Stenotrophomonas maltophilia infection ,ana‐lyze the characteristics of the bacteria infection and drug‐resistant strains of the area children .Methods Statistical analysis of 52 ca‐ses detected Stenotrophomonas maltophilia culture positive patients clinical data from September 2011 to September 2012 ,and the antibiotic susceptibility test results .Results Clinical data analysis showed that patients infected with Stenotrophomonas maltophilia had no difference on age and gender ,in the detection department was given priority to with of NICU and PICU ,82 .7% of infected children with SMA had a history of invasive procedures ,95 .92% of children with SMA had a history of penicillium carbon alkene drug use ,infection SMA patients in hospital for a long time with an average of (22 .3 ± 19 .0) days .Laboratory data analysis showed that Stenotrophomonas maltophilia main detection in sputum specimen type (63 .5% ) ,four kinds of commonly used clinical drug re‐sistance was higher ,sulfa drugs up to 21 .9% .Conclusion Stenotrophomonas maltophilia infection in children is closely related to carbapenem drug use and the invasive operation ,drug resistance in severe cases ,the rational use of antibiotics are crucial to treat‐ment .
