A kit for safe and easy insertion of a central vein cannula was devised. A small gauge (22 gauge) metal pilot needle was equipped with a Y-shaped hub which had a side-port to accept a small gauge (0.46 mm) Seldinger guide wire. Once the needle reached the vein, guidewire was threaded in through the side-port. There was no need to remove the pilot needle and no need to repeat vein puncture with a larger-bore needle. Three puncture methods were used with the kit: (1) the central approach via the internal jugular vein, (2) the supraclavicular approach via the junction of the internal jugular vein and subclavian vein, and (3) the infraclavicular approach via the subclavian vein. Each method was used on 20 patients, for total of 60 patients, with a high success rate. Less than 3 minutes were required from puncture to catheter insertion. No serious complications were encountered.
设计了一种用于安全、轻松插入中心静脉导管的套件。一个小规格（22号）的金属引导针配备了一个Y形针座，该针座有一个侧孔以容纳小规格（0.46毫米）的塞丁格导丝。一旦针进入静脉，导丝就通过侧孔穿入。无需拔出引导针，也无需用更大孔径的针重复静脉穿刺。该套件采用了三种穿刺方法：（1）经颈内静脉的中心入路，（2）经颈内静脉和锁骨下静脉交界处的锁骨上入路，（3）经锁骨下静脉的锁骨下入路。每种方法用于20例患者，共观察60例患者，成功率较高。从穿刺到导管插入所需时间不到3分钟。未遇到严重并发症。
