在新西兰使用的各种静脉导管的比较

中华临床营养杂志 1994年第2期12卷 12-18页

作者： b.C.Treuren D.C.Galletly 张忠涛新西兰惠灵顿医学院麻醉科

本研究检查了在新西兰允许使用的11种静脉导管的物理特性和临床特点,这11种导管是:Angiocath,b.aunule,Insyte,Jelco,J.M.S.,Medicut,Nipro,Quikcath,Surflo,Venflon、wallace导管。相同型号的不同导管间导管内、外径,管壁厚度相差很大,并因此造成导管流速相差亦很大,但导管流速与内径成线性关系。每种16号和22号的导管各40根,随机分配给麻醉医生在临床上常规使用,并要求麻醉医生填写一份关于所使用的导管的问题单(包括:放置导管是否成功,插入、持管是否容易,有无扭结,对包装是否满意)。对所填写的问题单进行了汇总和讨论。对22号导管临床使用后进行了显微镜观察,以判断是否有导管尖端变形,本研究发现Jelco导管尖端变形发生率最高(54％)。
