Central venous catheters are exchanged in cases of malfunction, suspected infections, or when another catheter type is required. It can be replaced by new venipuncture or using a guide wire. The guide wire technique should be used with a defective catheter or when the catheter type is to be changed. It is contraindicated at exit site infections or proven or suspected catheter infections. Due to possible cross contamination of new by old catheter material meticulous aseptic technique is required. A detailed description of the process of catheter exchange using a guide wire with special regard to the aseptic technique is given.
在出现功能故障、疑似感染或需要更换其他类型导管的情况下，需更换中心静脉导管。可通过重新进行静脉穿刺或使用导丝来更换。导丝技术应用于有缺陷的导管或需要更换导管类型时。在出口部位感染或已证实或疑似导管感染时禁用。由于新旧导管材料可能存在交叉污染，因此需要严格的无菌技术。本文详细描述了使用导丝更换导管的过程，尤其注重无菌技术。
