The aim of this study was to find a new external landmark for internal jugular vein (IJV) catheterization.
The locations of the right IJVs of 100 patients were examined by ultrasonography using the external jugular vein and the cricoid cartilage as landmarks, and in a clinical study, we catheterized the right IJVs of 100 patients using these landmarks.
By ultrasonography, the average distance from point A (a point 1.5 cm medial from the external jugular vein at the cricoid cartilage level) to the midpoint of the right IJV was 0.35 +/- 0.61 cm, and by clinical study, catheterization of the right IJV was successful in 99% (99/100) of patients. Patients required an average of 1.75 +/- 0.75 attempts, and no carotid puncture occurred.
This new method of IJV catheterization was found to have a high success rate and few complications.
本研究旨在寻找一种用于颈内静脉（IJV）置管的新体表标志。
以颈外静脉和环状软骨为标志，通过超声检查100例患者右侧颈内静脉的位置，并在一项临床研究中，使用这些标志对100例患者的右侧颈内静脉进行置管。
通过超声检查，从点A（环状软骨水平处颈外静脉内侧1.5 cm处的一点）到右侧颈内静脉中点的平均距离为0.35±0.61 cm，在临床研究中，99%（99/100）的患者右侧颈内静脉置管成功。患者平均需要1.75±0.75次尝试，且未发生颈动脉穿刺。
这种颈内静脉置管新方法成功率高且并发症少。
