Catheterization of the superior caval vein with the indirect technique of the alpha system is practically always successful. The integrated guide wire combines high elasticity with firmness; this makes it possible to employ highly flexible catheters thereby reducing tissue damage and, consequently, the incidence of thrombosis. The advantages of the indirect technique of catheterization of the caval vein are: minimum trauma at the site of puncture; a high success rate; avoidance of misplacement of the catheter (the catheter is safely guided by the plastic wire); avoidance of cardiac disturbances as the catheters are of uniform lenght or are graduated.
采用α系统间接技术对上腔静脉进行插管几乎总是成功的。集成导丝兼具高弹性和坚固性;这使得使用高度灵活的导管成为可能,从而减少组织损伤,进而降低血栓形成的发生率。上腔静脉插管间接技术的优点包括:穿刺部位创伤最小;成功率高;避免导管误置(导管由塑料导丝安全引导);由于导管长度一致或有刻度,可避免心脏干扰。
