【摘要】 目的分析重症烧伤患者发生中心静脉导管细菌定植的原因并探讨其防治措施。方法收集广州市红十字会医院烧伤整形科2005年1月至2007年4月重症烧伤患者行中心静脉置管的相关临床资料,对比导管细菌定植(CAC)的发生率。结果重度烧伤患者中心静脉导管细菌定植发生率为55.56%,明显高于文献报道的其他危重患者的发生率26.3%。不同置管部位,是否经过创面以及置管时间是否大于两周的导管细菌定植发生率差异无统计学意义(P>0.05)。结论重度烧伤患者中心静脉导管细菌定植的高发生率与创面感染不易控制、导管留置部位多在股静脉、导管经创面留置、留置时间过长等因素有关。多方面的干预才能减少导管相关性感染(CRI)的危险性。更多还原

【Abstract】 Objective To analyze the risk factors of bacterial colonization in severely burned patients with Central venous catheter,and explore the measures of prevention.Methods Ninety-seven cases with severe burn injury during March 2005 to January 2007 were enrolled in the study.The clinical data were collected and the incidence of CVC bacterial colonization was compared and analyzed.Results The incidence of CVC bacterial colonization in burn patients was 55.56%,much higher than that of other severe patients.The differences of incidence of CAC were insignificant between the groups of location of catheter in femoral vein and subclavian vein,the groups of through the wound and out of the wound,the groups of within two weeks and more than two weeks.Conclusions The major risk factors of this high incidence of CVC bacterial colonization in burn patients include the wound infection,the predominant location of catheter in femoral vein,the puncture through wound and long duration of catheter.Many measures should be taken in time to reduce the incidence.更多还原
