An intraluminal culture method was evaluated for central venous catheters and compared to conventional catheter tip cultures and cultures from the insertion site. The colonization-rate of the catheters was 43.7% using conventional tip culture, 34.4% with the intraluminal method and 40.1% at the skin puncture site. Only 37.5% of the catheters showed identical bacteria at the skin puncture site and catheter-tip, compared with 87.5% between intraluminal culture and catheter-tip culture (P less than 0.05).
对中心静脉导管的腔内培养方法进行了评估，并与传统的导管尖端培养及穿刺部位培养进行了比较。采用传统尖端培养法时导管的定植率为43.7%，腔内培养法为34.4%，皮肤穿刺部位为40.1%。只有37.5%的导管在皮肤穿刺部位和导管尖端显示相同细菌，而腔内培养与导管尖端培养之间这一比例为87.5%（P<0.05）。
