Radial artery cannulation for constant monitoring of arterial pressure and blood gases has become commonplace in the care of the seriously ill. The radial artery is readily accessible and is often regarded as carrying a negligible complication risk, because there is extensive collateral arterial flow in the hand. To the rarely reported cases of gangrene of the hand secondary to cannulation of the radial artery, this publication adds two, both survivors. One, a 46-year-old female with a clinical picture suggestive of mild Raynaud's disease, was treated by closed mitral commissurotomy; the second, a 44-year-old female, was treated for drug overdose complicated by cardiac arrest and renal shutdown.
通过桡动脉置管持续监测动脉压和血气，在重症患者护理中已很常见。桡动脉易于触及，且由于手部有丰富的动脉侧支循环，通常被认为发生并发症的风险可忽略不计。关于桡动脉置管后继发手部坏疽的病例报道很少，本文又增加了两例，两位患者均存活。一例是一名46岁女性，临床表现提示轻度雷诺病，接受了闭式二尖瓣交界切开术；另一例是一名44岁女性，因药物过量合并心脏骤停和肾衰竭接受治疗。
