Real-time ultrasound (US)-guided venipuncture has become the standard of care due to its reduced complications and higher success rate. There are various techniques for US-guided cannulation of the internal jugular vein (IJV); the transversal and longitudinal views are the most widely used. There is a less commonly used technique that combines the benefits of both methods.
Two main techniques for central line US-guided cannulation of the IJV are based on the location of the probe relative to the vessel and are known as the transversal view and the longitudinal view. The transversal view may make it difficult to identify the tip of the needle as it enters the vein, and the longitudinal view may not allow for visualization of surrounding structures. A third and less commonly used technique, the short axis in-plan view, aims to combine the benefits of both previous methods. In this technique, the entire needle can be tracked in real time as it enters the IJV, while also providing visualization of surrounding structures.
The short axis in-plane view technique for central venous line placements allows for real-time US-guided needle venipuncture with simultaneous visualization of surrounding structures.
实时超声（US）引导下的静脉穿刺因其并发症减少和成功率提高已成为护理标准。有多种用于超声引导下颈内静脉（IJV）置管的技术；横切面和纵切面是最常用的。有一种不太常用的技术结合了这两种方法的优点。
两种主要的 IJV 中心静脉 US 引导下置管技术是基于探头相对于血管的位置，分别称为横切面和纵切面。横切面可能会使针尖进入静脉时难以识别，而纵切面可能无法显示周围结构。第三种也是不太常用的技术，短轴平面内视图，旨在结合前两种方法的优点。在这种技术中，整个针头可以在实时跟踪下进入 IJV，同时还可以显示周围结构。
