The rates of thrombosis and infection were studied in 102 patients who underwent 107 radial artery cannulations. A Leader cath, ORX cannula (Vygon) was placed using Seldinger's method. It was continuously perfused with an heparinized 5% dextrose solution via an Intraflo fixed upon an arterial catheter. The cannulae were used for arterial pressure monitoring and measuring arterial blood gases. Before removing the catheter, a forearm arteriography was realized with 20 ml Hexabrix. Bacterial examination and culture were carried out on the cannula tips. 70 men and 32 women (mean age: 50 +/- 17 years) were studied. Mean duration of cannulation was 9 +/- 7 days (range: 1-34 days). Complete or partial radial artery thrombosis occurred in 85%. Complete thrombosis occurred more frequently in women (84%) than in men (54%) (p less than 0.05). There was no correlation between thrombosis and duration of cannulation (9.9 +/- days for thrombosis and 7.9 +/- 4.3 days without thrombosis). Bacterial cultures of cannula tips were positive in 24% of cannulations. Pathogenic bacilli grew in only 9%. Infected cannulas were in situ for 9.9 +/- 7 days against 8.9 +/- 6.7 days for the non-infected cannulas (NS). There was no correlation between infection and radial artery thrombosis. The use of another material (silicone, Teflon) must be studied in order to decrease the occurrence of thrombosis.
对102例接受了107次桡动脉插管的患者的血栓形成率和感染率进行了研究。采用Seldinger法置入Leader cath、ORX套管（Vygon）。通过固定在动脉导管上的Intraflo，用肝素化的5%葡萄糖溶液持续灌注。这些套管用于动脉压监测和动脉血气测量。在拔除导管前，用20 ml Hexabrix进行前臂动脉造影。对套管尖端进行细菌检查和培养。研究对象为70名男性和32名女性（平均年龄：50±17岁）。平均插管时间为9±7天（范围：1 - 34天）。85%发生了完全或部分桡动脉血栓形成。完全血栓形成在女性中（84%）比在男性中（54%）更常见（p＜0.05）。血栓形成与插管时间之间无相关性（血栓形成组为9.9± 天，无血栓形成组为7.9±4.3天）。24%的插管套管尖端细菌培养呈阳性。仅9%培养出致病杆菌。感染套管在位时间为9.9±7天，未感染套管为8.9±6.7天（无显著性差异）。感染与桡动脉血栓形成之间无相关性。必须研究使用其他材料（硅胶、聚四氟乙烯）以降低血栓形成的发生率。
