Arterial catheterization is used frequently in the management of critically ill patients, both for continuous blood pressure monitoring and access to the arterial circulation to obtain frequent blood gas measurements. The procedure is usually easily accomplished at the bedside using percutaneous methods such as the Seldinger technique to cannulate the radial, brachial, axillary, femoral, or dorsalis pedis artery. Meticulous attention to aseptic technique is necessary during insertion and catheter maintenance to minimize the risk of catheter-related infection. Other potential complications include hemorrhage, ischemia, arteriovenous fistula, and pseudoaneurysm formation.
动脉导管插入术在危重症患者的管理中经常使用，既用于持续血压监测，也用于通过动脉循环通路频繁获取血气测量值。该操作通常在床边使用经皮方法（如Seldinger技术）轻松完成，以插入桡动脉、肱动脉、腋动脉、股动脉或足背动脉。在插入和导管维护过程中，必须严格注意无菌技术，以尽量减少导管相关感染的风险。其他潜在并发症包括出血、缺血、动静脉瘘和假性动脉瘤形成。
