The use of a guidewire to facilitate the placement of an IV cannula through a cutdown is described. This technique was taught to 24 novice operators (medical students and first-year residents). In a randomized, prospective, crossover study, their performance of this technique in an animal model was compared with the use of the classic cutdown technique. The modified technique was performed 22% (two minutes, 13 seconds) more rapidly, on average, than the classic technique (P less than .05). Other potential advantages of this technique are discussed.
本文描述了使用导丝辅助经切开置入静脉套管针的方法。该技术教授给了24名新手操作者（医学生和一年级住院医师）。在一项随机、前瞻性、交叉研究中，将他们在动物模型中使用该技术的操作表现与传统切开技术的使用情况进行了比较。改良技术平均比传统技术快22%（两分钟13秒）（P<0.05）。本文还讨论了该技术的其他潜在优势。
