作者应用不同硬度的锥形带有可取出针芯的弹簧导丝及Grollman型肺动脉导管快速插入技术。插管使用带聚四氟乙稀鞘的Amplatz导丝,直径0.035时(0.89mm),长145cm,有3mmJ型顶端及6.7F110cm长有3.5cm臂的Grollman聚乙稀导管,导丝(中心轴)的远端有一10cm锥形末端为一短弹形顶端。导丝导管经Seldinger技术刺入 The authors applied a spring-loaded guide wire with a detachable needle core and a Grollman pulmonary artery catheterization technique with different hardness cones. A cannula was used with a polytetrafluoroethylene sheath Amplatz guidewire, a Grollman polyethylene catheter having a diameter of 0.035 (0.89 mm), a length of 145 cm, a 3 mm J-shaped tip, and a 6.7 F110 cm long 3.5 cm arm. The guidewire ) Distal end of a 10cm tapered tip is a short-billed tip. Guide wire catheter piercing by Seldinger technique
