During procedures (such as cardiac catheterizations) that use contrast media, or dyes, large amounts of unused dye can become contaminated with the patient's blood and must be thrown out. Radiographic contrast media conservation systems (RCMCSs) are administration sets designed to reduce the waste of these expensive dyes by (1) isolating the bags or bottles supplying the dyes from contamination, allowing the remaining contents to be used again on another patient, and (2) minimizing the amount of dye left in the administration set (and therefore discarded) at the end of the procedure. In this Evaluation, we examined five burette RCMCSs from three suppliers. We tested the systems for their ability to protect the source containers from contamination, for their performance and design features, and for their ease of use. We also provide information on transfer line assembly RCMCSs, which perform some of the same functions but without using a burette, in a supplementary article within this Evaluation. In addition, a brief Purchasing Guide provides recommendations on deciding whether to purchase RCMCSs and how to choose among systems.
在使用造影剂（即染料）的操作过程中（如心脏导管插入术），大量未使用的染料可能会被患者血液污染，必须丢弃。放射造影剂保存系统（RCMCSs）是一种给药装置，旨在通过以下方式减少这些昂贵染料的浪费：（1）将供应染料的袋子或瓶子与污染隔离开来，使剩余的染料能够再次用于其他患者；（2）在操作结束时，尽量减少给药装置中残留（因此会被丢弃）的染料量。在本评估中，我们检查了来自三个供应商的五种滴定管式RCMCSs。我们测试了这些系统保护源容器不受污染的能力、它们的性能和设计特点以及易用性。在本评估的一篇补充文章中，我们还提供了关于传输线组装式RCMCSs的信息，这些系统执行一些相同的功能，但不使用滴定管。此外，一份简短的采购指南提供了有关决定是否购买RCMCSs以及如何在不同系统中进行选择的建议。
