摘要/Abstract

摘要： 目的探究经外周置入中心静脉导管术（PICC）导管相关性感染（catheter relatedinfection,CRI）现状及危险因素。方法以2017—2018年丹东市某医院进行PICC治疗的患者为研究对象,从医院病历信息管理系统中导出患者性别、年龄、合并基础疾病、穿刺部位、穿刺方法、穿刺次数、导管材料、PICC导管留置时间、使用激素、导管类型、置管经验、PICC治疗季节、疾病类型等信息,并对PICC感染情况进行监测。采用描述流行病学分析方法进行分析,并采用单、多因素分析方法对导管相关感染发生影响因素进行分析。结果共收集PICC治疗患者信息984条,男女性别比为1.23∶1,年龄18~79岁,以60~79岁为主,占70.43%。主要穿刺部位为贵要静脉,占81.91%。共有88例（8.94%）发生CRI;其中局部感染58例（65.91%）,血流感染25例（28.41%）,其他5例（5.68%）。88例CRI患者中共检测出117株病原菌,以革兰阳性菌为主,占55.55%。合并基础疾病（OR=2.910）、盲穿（OR=2.705）、穿刺次数≥2次（OR=17.655）、PICC导管留置时间≥30 d（OR=2.179）、操作人员置管经验<50次（OR=6.994）、夏季（OR=4.402）和春季（OR=2.416）行PICC治疗是PICC治疗患者发生CRI的危险因素。结论 PICC治疗患者具有较高的CRI发生风险,病原菌以革兰阳性菌为主,且感染的发生影响因素较多,应针对其采取相应的预防干预措施,以提高PICC治疗患者的临床疗效。
