To demonstrate an asymmetry of the internal jugular veins, a finding which will have consequences for catheterization.
Prospective study.
The medical ICU of a university-affiliated teaching hospital.
Eighty critically ill consecutive patients.
Measurement of the cross-sectional area of the internal jugular veins. Search for an asymmetry, defined as an area at least twice that of the contralateral vein.
An asymmetry was noted in 62.5% of the patients. The dominant vein was the right in only 68 % of these cases. In addition, 23% of the 160 jugular internal veins had an area of 0.4 cm2 or less.
Using a simple technique, ultrasound identifies the dominant internal jugular vein, thus indicating the safer side before blind catheterization.
证明颈内静脉不对称这一发现对导管插入术有影响。
前瞻性研究。
一所大学附属医院的医学重症监护病房。
80例连续入住的危重症患者。
测量颈内静脉的横截面积。寻找不对称情况，定义为一侧静脉面积至少是对侧静脉的两倍。
62.5%的患者存在不对称情况。在这些病例中，仅68%的患者优势静脉为右侧。此外，160条颈内静脉中有23%的横截面积为0.4平方厘米或更小。
超声使用一种简单技术可识别优势颈内静脉，从而在盲目进行导管插入术前指明更安全的一侧。
