Peripheral arterial catheter insertion is a common procedure for critically ill patients requiring frequent blood gas sampling and continuous blood pressure monitoring. There are clear advantages of ultrasound-guided arterial cannulation, which have shown to be more effective in reducing complications, time to successful cannulation, number of attempts, and overall first-time success rates. Evidence suggests that using palpation alone has a first-time success rate of less than 70% yet is still a widely performed technique. A systematic evaluation may be required to reduce variations in arterial catheterization practices.
The arterial insertion method is a systematic evaluation to aid in arterial catheter insertion with ultrasound guidance, intended to improve the procedural approach. The process of arterial insertion method ensures appropriate choice of zone selection to optimize catheter longevity and performance in patients requiring arterial access. Moving the insertion site proximally 4 cm from the red zone into the green zone may reduce mechanical complications and preserve catheter performance and dwell time.
The standardization of ultrasound guidance in arterial catheterization promotes vessel health and patient safety through device and site optimization. The arterial insertion method systematic evaluation may be utilized to reduce variation in practice and promote the use of ultrasound as a standard for the insertion of radial arterial catheters.
外周动脉导管插入术是一种常见的程序，适用于需要频繁血气采样和持续血压监测的危重症患者。超声引导下的动脉置管具有明显的优势，它在减少并发症、置管成功率、尝试次数和总体首次成功率方面都更有效。有证据表明，单独使用触诊的首次成功率低于 70%，但它仍然是一种广泛应用的技术。为了减少动脉置管操作的差异，可能需要进行系统评估。
动脉插入方法是一种系统评估，旨在通过超声引导来辅助动脉导管插入，以改善手术方法。动脉插入方法的过程确保了适当的区域选择，以优化需要动脉通路的患者的导管寿命和性能。将插入部位从红色区域向近端移动 4cm 进入绿色区域，可能会减少机械并发症，并保持导管性能和留置时间。
通过设备和部位优化，动脉置管中超声引导的标准化促进了血管健康和患者安全。动脉插入方法的系统评估可用于减少实践中的差异，并促进将超声作为桡动脉导管插入的标准。
