目的 观察经皮中心静脉插管术后感染发生率。方法 根据留管时间分为甲、乙、丙 3组 ,插管部位分为A、B两组。术后定期做血培养监测 ,同时观察插管局部的感染发生情况。结果 甲、乙组之间 ,经统计学处理P>0 .0 5 ,无显著性差异 ,但甲、丙组之间比较P <0 .0 1,有高度显著性差异。A、B两组比较 ,P <0 .0 1,有高度显著性差异。结论 留管 1～ 2周时间是安全的 ,超过 2～ 3周 ,感染率上升。股静脉穿刺插管的术后感染率明显高于锁骨下及颈静脉插管者 ,另外 ,术中术后严格各项无菌操作对避免感染发生也是至关重要的
Objective To observe the incidence of infection after percutaneous central venous catheterization. Methods According to stay time into A, B, C three groups, intubation site is divided into A, B two groups. Regular postoperative blood culture monitoring, while observing the occurrence of intubation infection. Results A, B between the statistical analysis of P> 0.05, no significant difference, but A, C between the group P <0 01, a highly significant difference. A, B two groups, P <0. 01, a highly significant difference. Conclusion It is safe to leave the tube for 1 to 2 weeks. After more than 2 to 3 weeks, the infection rate increases. Postoperative infection rate of femoral vein catheterization was significantly higher than that of subclavian and jugular vein catheterization. In addition, strict intraoperative and postoperative sterility was also crucial to avoid infection
