We present two cases of misplaced central venous catheters having in common the absence of free blood return from one lumen immediately after placement. The former is a case of right hydrothorax associated with central venous catheterization with the catheter tip in intra-pleural location. In this case the distal port was never patent. In the latter case there was an increased aspiration pressure through the middle port due to a catheter looping. The absence of free flow on aspiration from one lumen of a central catheter should not be undervalued. In these circumstances the catheter should not be used and needs to be removed.
我们报告两例中心静脉导管位置不当的病例，其共同特点是置管后立即有一个管腔无回血。前者是与中心静脉置管相关的右侧胸腔积液病例，导管尖端位于胸腔内。在这种情况下，远端端口从未通畅。在后者中，由于导管盘绕，通过中间端口的抽吸压力增加。中心静脉导管一个管腔抽吸时无回血这一情况不应被忽视。在这些情况下，不应使用该导管，需要将其拔除。
