Abstract：
Radial arterial catheters (RAC) are used extensively across critical care settings (Anesthesia, Intensive Care, Emergency Medicine) for continuous hemodynamic monitoring, allowing for immediate adjustments in vasopressor therapies and blood collection. Radial catheter failures are an ongoing significant issue for critical care clinicians with reported incidences at almost 25%. Common complications include loss of function, lack of blood return, poor quality waveforms and dislodgement, posing potential patient risks, and sudden loss of intra-arterial monitoring frequently requires prompt replacement. Contemporary research and technological improvements have highlighted several concepts to enhance the approach of RAC insertion and management while reducing immediate and late complications. The authors have prioritized the following 10 \"best practice\" aspects that may improve overall device function and reliability.
摘要：
桡动脉导管(RAC)在重症监护环境中广泛使用(麻醉，重症监护,急诊医学）用于连续血流动力学监测，允许立即调整血管加压药治疗和血液收集。放射状导管失效对于重症监护临床医生来说是一个持续存在的重大问题,报告的发生率接近25%。常见的并发症包括功能丧失，缺乏血液回流，质量差的波形和移位，构成潜在的患者风险，动脉内监测的突然丢失经常需要及时更换。当代研究和技术改进强调了几个概念，以增强RAC插入和管理的方法，同时减少即时和晚期并发症。作者优先考虑了以下10个“最佳实践”方面，这些方面可能会提高设备的整体功能和可靠性。
