留置途径对中心静脉导管感染的影响

Influence of remaining needle on central venous catheter-related infection

目的探讨不同留置途径对中心静脉导管相关性感染的影响。方法对重症监护病房采用不同途径留置中心静脉导管的患者进行回顾性分析,比较经不同途径留置中心静脉置管而发生感染的差异。结果股静脉发生感染率最高(31.2%),锁骨下和颈内静脉置管发生感染率次之(13.7%、15.4%),经外周静脉置管发生感染率最低(3.8%),三者差异有显著性(P<0.01),并且感染的致病菌以革兰氏阳性菌为主。结论中心静脉置管的感染与留置途径有明显的相关性,采用外周静脉置管途径可以明显降低中心静脉置管的感染率。

Objective To investigate the influence of central venous catheter-related infection among different remaining needle. Methods The infection of central venous catheter with remaining needle in patients of comprehensive ICU was analyzed. Results There was the highest infection rate （31.2%） in femoral vein catheter group, followed by subclavian vein catheter group and jugular vein catheter （13.7 %, 15.4% ）, peripheral venous catheter infection rate was lowest （3.8%）. The difference among three groups was statistical significance （P〈0. 01）. Gram-positive bacteria was the major pathogenic bacterium. Conclusion The infection of central venous catheter was correlated with the puncture approach, central venous catheter to adopt the peripheral venous puncture approach may lower significantly catheter-related infection rate.
