Although catheters are commonplace in hospital settings, there is scarce literature discussing the internal and external retention mechanisms used to aid in catheter fixation. Additionally, exact definitions and detailed information on internal and external retention mechanisms are almost non-existent in the literature. This article serves three primary purposes. The first purpose is to define internal and external catheter retention mechanisms, describe how they work, and provide examples of each that are routinely used in healthcare settings. The second goal of this paper is to provide a literature review comparing various aspects of the different types of internal and external catheter retention mechanisms discussed in the paper, including performance variance and the advantages and disadvantages of each. The third aim of this article is to provide a brief overview of catheter dislodgment, including the rates at which this occurs, the problems that can arise, and the best treatment option when this does occur.
尽管导管在医院环境中很常见，但关于用于辅助导管固定的内部和外部固定机制的文献却很少。此外，文献中几乎不存在关于内部和外部固定机制的确切定义和详细信息。本文有三个主要目的。第一个目的是定义导管的内部和外部固定机制，描述它们的工作原理，并提供在医疗环境中常规使用的每种机制的示例。本文的第二个目标是提供一篇文献综述，比较本文中讨论的不同类型的内部和外部导管固定机制的各个方面，包括性能差异以及每种机制的优缺点。本文的第三个目的是简要概述导管移位，包括其发生的频率、可能出现的问题以及发生时的最佳治疗选择。
