Percutaneous radial artery cannulation is commonly used for continuous monitoring of blood pressure and estimation of arterial blood gases. The purpose of this study is to define the incidence of radial artery thrombosis and associated hand ischaemia after cannulation. A prospective study of 40 patients who underwent radial artery cannulation was carried out with patients examined before and after cannulation for radial and ulnar pulses. Doppler waveforms, and finger/brachial and finger/wrist pressure indices were obtained. After cannulation 27.5% of patients developed abnormal radial artery flows with 10% having absent pulses and none having any symptoms of hand ischaemia. Radial artery cannulation is a safe procedure when performed properly and is associated with a very low incidence of hand ischaemia, despite a 27.5% incidence of abnormal radial artery flow after cannulation.
经皮桡动脉置管常用于连续监测血压和评估动脉血气。本研究的目的是确定置管后桡动脉血栓形成及相关手部缺血的发生率。对40例行桡动脉置管的患者进行了一项前瞻性研究，在置管前后对患者的桡动脉和尺动脉搏动进行检查。获取了多普勒波形以及手指/肱动脉和手指/腕部压力指数。置管后，27.5%的患者桡动脉血流出现异常，10%的患者脉搏消失，且无患者出现任何手部缺血症状。尽管置管后桡动脉血流异常发生率为27.5%，但桡动脉置管操作得当则是一种安全的操作，且手部缺血发生率非常低。
