Indwelling right atrial catheters provide continuous access to the venous circulation for the purpose of long-term alimentation and blood collection. Two types of central venous systems are the Broviac and Hickman catheters. In general, the Hickman is more versatile, allowing easy blood sample collection, in addition to continuous intravenous fluid and drug administration. Two cases are presented where apparent erroneous tobramycin blood samples were collected through one of these catheter systems. One case compares Hickman tobramycin blood levels with standard peripheral venicollection. Possible ramifications and solutions to the problem are discussed.
留置右心房导管可提供持续进入静脉循环的途径，用于长期营养供给和血液采集。两种类型的中心静脉系统是Broviac导管和Hickman导管。一般来说，Hickman导管用途更广，除了可连续进行静脉输液和给药外，还便于采集血样。本文介绍了两例通过其中一种导管系统采集到明显错误的妥布霉素血样的病例。其中一例将通过Hickman导管采集的妥布霉素血药浓度与标准外周静脉采血结果进行了比较。文中还讨论了该问题可能产生的后果及解决办法。
