目的了解血液净化患者导管相关性菌血症的发生率和影响因素。方法回顾性分析326例次中心静脉置管行血液净化治疗患者的年龄、性别、置管时间、置管方式和菌血症的关系及分析致病菌的构成比。结果 326例次中心静脉置管中,导管相关性菌血症的感染率是9.5%,按导管日计算为3.22例次/1000导管日;股静脉导管感染率6.74例次/1000导管日明显高于颈内静脉导管(2.83)及长期导管(2.19)(P<0.05),留置时间长短与感染的关系有统计学意义(P<0.05);金黄色葡萄球菌(38.7%)是最常见致病菌,其次为屎肠球菌、表皮葡萄球菌、绿脓杆菌等。结论中心静脉导管留置时间的长短和导管相关性菌血症的发生相关。
Objective To understand the incidence and influencing factors of catheter-related bacteremia in patients with blood purification. Methods A retrospective analysis of 326 cases of secondary venous catheterization in patients with blood purification treatment of age, sex, catheterization time, catheterization and bacteremia and the relationship between pathogens composition ratio. Results 326 cases of sub-central venous catheterization, catheter-related bacteremia infection rate was 9.5%, according to the catheter day was 3.22 cases / 1000 catheter days; femoral vein catheter infection rate 6.74 cases / 1000 catheter day was significantly higher (P <0.05). There was a significant correlation between the duration of indwelling and infection in the internal jugular vein catheter (2.83) and the long-term catheter (2.19) (P <0.05). Staphylococcus aureus (38.7%) was the most common Bacteria, followed by Enterococcus faecium, Staphylococcus epidermidis, Pseudomonas aeruginosa and so on. Conclusion The length of central venous catheter indwelling is related to the occurrence of catheter-related bacteremia.
