摘要
摘要目的分析并研究新生儿感染性肺炎的常见病原体,调查并了解其耐药情况及相关临床特征,以便为临床治疗提供依据.方法选取我院在２０１２年３月到２０１５年７月收治的１５４９例诊断为新生儿感染性肺炎的患者作为研究对象,对常见的４种肺炎病原体的耐药性情况进行分析,调查各个病原体组间新生儿患者的临床特征.结果本研究经病原体检测为阳性的新生儿患者５２９例,阳性检出率为３４．１５％,其中感染常见４种常见病原体的新生儿肺炎患者４１７例,占７８．８３％.其中金黄色葡萄球杆菌１１４例,占２１．５５％,大肠埃希菌１０７例,占２０．２３％,肺炎克雷伯杆菌１０２例,占１９．２８％,阴沟肠杆菌９４例,占１７．７７％,此４种为新生儿肺炎的常见病原体.感染金黄色葡萄球杆菌的新生儿出生体重一般正常,且大多数在出生２４h以后出现症状入院治疗,感染G－杆菌特别是感染肺炎克雷伯杆菌的新生儿体重较低,且在出生２４h以内便出现症状.入院治疗,有超过半数的G－杆菌耐药２到４代头孢菌素.结论新生儿感染性肺炎患者,最常见的病原体为G－杆菌,而且较多发生在低体重新生儿群体当中,其发病时间早,而且G－杆菌对头孢菌素具有较高的耐药性,需要在临床上加以重视,采取恰当的干预手段.关键词新生儿感染性肺炎;常见病原体;耐药ThecommonpathogenofneonatalinfectiouspneumoniaandtheanalysisofclinicalfeaturesliXiang－meiCaiXuRenDezhiThosedayspeople??shospitalofpeＧdiatrics６３７６００innanchongcityinsichuanprovinceAbstractObjectivetoanalyzeandstudythecommonpathogensoftheneonatalpneumonia,investigateandunderstandthedrugresistancesituationandreＧlatedclinicalcharacteristics,inordertoprovidethebasisforclinicaltreatment．MethodsselectourhospitalinMarch２０１２toJuly２０１２werediagnosed１５４９casesofneonatalpneumoniapatientsastheresearchobject,thecommon４pneumoniapathogenresistancesituationanalysis,investigationgroupofneonatalclinicalfeaＧturesbetweenvariouspathogens．Testedpositivefortheresultsofthisstudyisthepathogenofneonatalpatient５２９examples,positivedetectionratewas３４．１５％,includinginfectioncommon４kindsofcommonpathogensof４１７patientswithneonatalpneumonia,accountingfor７８．８３％．Includingstaphylococcusballcoli１１４cases,accountingfor２１．５５％,１０７casesofe．coli(２０．２３％),１０２caseswithklebsiellapneumoniae,accountedfor１９．２８％,sewere．coli９４cases,acＧcountingfor１７．７７％,thefourkindsofcommonpathogensofneonatalpneumonia．Colistaphylococcusinfectionballnormalbirthweight,andmostinhospitalwasborn２４hafteronsetofsymptoms,G－bacillusinfectionespeciallywithklebsiellapneumoniaeinfectionoflowbirthweight,andthendevelopedsymptomswithＧin２４hafterbirth．Hospitaltreatment,morethanhalfoftheG－bacilliresistant２to４generationcephalosporins．ConclusionthemostcommoncausesofneoＧnatalpneumoniapatientsisG－bacillus,andmoreinlowbirthweightgroup,theonsettimeearly,andG－bacillusofcephalosporinshavehighresistance,needsKatetyenwtioornds,takeappropriateinterventions．thenewbornpneumonia;Commonpathogens;resistance中图分类号R７２２．１文献标识码B文章编号１００８－６３１５(２０１５)１２－０８３７－０２
