中心静脉导管留置后病原菌感染的临床研究

Clinical reserch of pathogenic bacterial infection caused by central venous catheters

目的分析中心静脉导管引起病原菌感染情况及相关因素。方法对笔者所在医院2008年6月～2011年5月258例行中心静脉置管患者送检的标本进行回顾性分析,总结感染相关因素。结果中心静脉导管培养阳性60例,阳性率为23.3%,中心静脉导管培养阳性患者中,老年组与非老年组差异有统计学意义(P<0.05),留置部位差异有统计学意义(P<0.05)。结论机体抵抗力低下、老年患者、置管部位不当是高危因素,应采取综合性防范措施。

Objective To investigate the condition of pathogenic bacterial infectiin caused by centeral venous catheters and the re lated factors. Methods From June 2008 to May 2011, the samples of 258 patients with central venous catheters in the author＇s hospital were reviewed retrospectively. To summarise the infectiion associated factors. Results There were 60 cases with positive culture of central venous catheters. The positive rate was 23.3%. There was significant difference in positive rate between the elderly and the non elderly （P 〈 0. 05 ）. There was significant difference in positive rate among different locations of center venous catheters （ P 〈 0. 05 ）. Conclusion The low resistance of body, the elderly and improper locations of catheters are high risk factors. The comprehensive precautionary measures should be adopted.
