To describe the possible ultrasound guidance techniques for the insertion of central venous catheters (CVCs), with emphasis particularly to the lateral short axis in-plane technique.
Numerous articles have shown significant benefits of using ultrasound guidance for venous access. Two main approaches to vein puncture are available, when considering visualization of the needle during its entry into the vein under the ultrasound beam: in-plane and out-of-plane, which can be combined with two types of vein visualization, placing the ultrasound probe on the vein long axis or short axis.
Advantages and limitations in internal jugular vein (IJV) cannulation for long-term dialysis CVCs are described for the above-mentioned approaches and visualizations. The lateral short axis in-plane technique has virtually no limitations, ensuring most benefits.
The lateral short axis in-plane technique should be considered the first-line technique for IJV cannulation.
描述中心静脉导管（CVC）置入可能采用的超声引导技术，尤其着重于外侧短轴平面内技术。
众多文章已表明使用超声引导进行静脉穿刺具有显著益处。在考虑超声束下穿刺针进入静脉过程中的可视化时，有两种主要的静脉穿刺方法：平面内和平面外，这两种方法可与两种静脉可视化方式相结合，即将超声探头置于静脉长轴或短轴上。
针对上述方法和可视化方式，描述了长期透析用CVC颈内静脉（IJV）置管的优势和局限性。外侧短轴平面内技术几乎没有局限性，能确保最大益处。
外侧短轴平面内技术应被视为IJV置管的一线技术。
