Radial artery catheterization in elderly patients may be difficult. The "liquid stylet" created by slow intra-arterial fluid injection facilitates insertion of arterial cannulae, and proved effective in 14 consecutive patients in whom percutaneous radial artery catheterization was otherwise unsuccessful. This technique is useful when difficulty in radial artery cannulation is encountered.
老年患者的桡动脉插管可能会有困难。通过缓慢动脉内注射液体形成的“液体探条”有助于动脉套管的插入，并且在连续14例经皮桡动脉插管原本不成功的患者中证明是有效的。当遇到桡动脉插管困难时，这项技术很有用。
