中文摘要：

目的分析经外周穿刺中心静脉导管置管（PICC）术后感染的危险因素，为PICC术后导管感染的管理及预防提供理论依据。方法回顾性分析医院2001年12月-2012年12月612例行PICC患者的临床资料，统计分析患者导管相关感染的危险因素。结果612例行PICC的患者中共发生导管相关性感染42例，其感染发生率为6．9％；单因素显示，年龄〉50岁、置管时间〉30d、病程〉3年的患者导管相关性感染率较高，分别为10．8％、10．4％、10．1％，差异有统计学意义（P〈0．05）。结论年龄、置管时间和病程是PICC术后导管感染的高危因素，积极采取相应地预防措施有利于降低导管感染的发生。

英文摘要：

OBJECTIVE To investigate the risk factors for the infections after peripherally inserted central catheterization （PICC） so as to provide theoretical basis for the prevention and control of catheter-related infections after PICC. METHODS The clinical data of 612 patients who underwent the PICC in the hospital from Dec 2001 to Dec 2012 were retrospectively analyzed, then the risk factors for the catheter-related infections were statistically analyzed. RESULTS Among the 612 patients undergoing PICC, the catheter-related infections occurred in 42 cases with the incidence rate of 6.9X. The univariate analysis indicated that the more than 50 yeas of age, catheter indwelling time more than 30 days, and illness course more than three years were the related risk factors for the catheter-related infections, the incidence rates were 10.8%, 10.4%, and 10.1%, respectively, the difference was statistically significant （P〈0.05）. CONCLUSION The age, catheter indwelling time, and illness course are the high risk factors for the catheter-related infections after PICC, the implementation of corresponding prevention and treatment measures may contribute to the reduction of incidence of catheter-related infections.
