中心静脉导管相关性感染危险因素调查分析

Risk factors of central venous catheter-related infections

目的通过对中心静脉导管相关性感染的调查分析,探讨中心静脉导管相关性感染的防治。方法分析2007年1月-2008年12月临床31例中心静脉导管感染病例。结果 31例置管感染患者置管时间最短7 d,最长58 d,平均置管时间23.38 d;感染发生>7 d者29例,占93.55%,其中>2周的22例,占70.97%;20例感染前全身性使用抗菌药物,占64.52%;感染与导管留置时间、置管部位等相关,危重、老年患者是导管相关性感染的易感人群。结论减少导管留置时间,长期留置导管患者需加强导管的监测与管理。

OBJECTIVE To explore the risk factors and prevention measures of central venous catheter related infections （CRI）. METHODS Thirty-one cases from Jan 2007 to Dec 2008 in our hospital were analyzed retrospectively. RESULTS CRI was relate.d to the indwelling time, location of catheter. The most susceptible crowd of central venous catheter-related infections was those patients in critical conditions, senile patients. CONCLUSION Shortening catheter indwelling time is important to prevent CRI through augmenting the monitoring and the careful nursing.
