RATIONALE AND OBJECTIVES
To improve the safety and success of selective and superselective arterial catheterization in the rabbit.
METHODS
A 2-F catheter introducer system was devised that consisted of the sheath of an 18-gauge, 5.1-cm sheath needle and a hemostatic valve attached to the hub of the sheath. The system was tested in 14 adult male New Zealand white rabbits with regard to ease of insertion and facilitation of superselective arterial catheterization.
RESULTS
The introducer system was easily placed in all rabbits, and no bleeding was seen around the sheath at the puncture site. Preshaped 2-F polyethylene catheters were readily inserted through the assembly and sheath. The valve prevented bleeding from around the catheter, and the side-arm flush tube served as a route for heparinization. The system greatly facilitated the manipulation of 2-F angiographic catheters.
CONCLUSION
Use of the introducer system with a 2-F polyethylene angiographic catheter improved the success of selective and superselective arterial catheterization in the rabbit.
原理与目的
提高兔选择性和超选择性动脉插管的安全性与成功率。
方法
设计了一种2F导管导入系统，由一根18号、5.1厘米长的鞘针的鞘管和一个连接在鞘管针座上的止血阀组成。该系统在14只成年雄性新西兰白兔身上进行了插入简便性和超选择性动脉插管便利性的测试。
结果
导入系统在所有兔子身上都能轻松放置，穿刺部位鞘管周围未见出血。预塑形的2F聚乙烯导管能轻松通过组件和鞘管插入。阀门可防止导管周围出血，侧臂冲洗管可作为肝素化的途径。该系统极大地便于了2F血管造影导管的操作。
结论
使用带有2F聚乙烯血管造影导管的导入系统提高了兔选择性和超选择性动脉插管的成功率。
