Arterial cannulation is usually performed to allow continuous blood pressure monitoring or frequent arterial blood sampling. Relative contraindications to the procedure include bleeding abnormalities and peripheral vascular disease. The radial artery is the site most frequently used because the hand generally has good collateral circulation. Percutaneous cannulation is the preferred method of insertion. To avoid transecting the artery, advance the needle-catheter assembly slowly; blood return confirms arterial placement. there should be no resistance to needle advancement. Bleeding is the most common complication of arterial cannulation, but ischemia and infection have greater clinical significance.
动脉插管通常用于持续血压监测或频繁采集动脉血样。该操作的相对禁忌证包括出血异常和周围血管疾病。桡动脉是最常使用的部位，因为手部通常有良好的侧支循环。经皮插管是首选的插入方法。为避免切断动脉，缓慢推进针-导管组件；回血可确认动脉置管位置。进针时不应有阻力。出血是动脉插管最常见的并发症，但缺血和感染具有更大的临床意义。
