Abstract：
Point-of-care ultrasound (POCUS) of the internal jugular vein (IJV) offers a non-invasive means of estimating right atrial pressure (RAP), especially in cases where the inferior vena cava is inaccessible or unreliable due to conditions such as liver disease or abdominal surgery. While many clinicians are familiar with visually assessing jugular venous pressure through the internal jugular vein, this method lacks sensitivity. The utilization of POCUS significantly enhances the visualization of the vein, leading to a more accurate identification. It has been demonstrated that combining IJV POCUS with physical examination enhances the specificity of RAP estimation. This review aims to provide a comprehensive summary of the various sonographic techniques available for estimating RAP from the internal jugular vein, drawing upon existing data.
摘要：
颈内静脉（IJV）的护理点超声（POCUS）提供了一种估计右心房压力（RAP）的非侵入性手段，尤其是在由于肝病或腹部手术等原因导致下腔静脉无法进入或不可靠的情况下。虽然许多临床医生熟悉通过颈内静脉视觉评估颈静脉压，这种方法缺乏灵敏度。POCUS的利用显着增强了静脉的可视化，导致更准确的识别。已经证明，将IJVPOCUS与体格检查相结合可以增强RAP评估的特异性。这篇综述旨在提供可用于从颈内静脉估计RAP的各种超声技术的全面总结，利用现有数据。
