Abstract

OBJECTIVE

To determine the dimensions and depth of the right internal jugular vein (RIJV) in low birth weight newborns by ultrasound and assess the differences in weight and determine the relationship of the vein with the carotid artery.

METHOD

We performed a vascular assessment of the RIJV in 100 low birth weight newborns. The subjects were divided into three groups, low birth weight (LBW) newborns, <2500 g; very low birth weight (VLBW) newborns, <1500 g; and extremely low birth weight (ELBW) newborns <1000 g.

RESULTS

Of the newborns, 39% had LBW, 33% had VLBW, and 28% had ELBW. The medians were gestational age 31 weeks, weight 1300 g, anteroposterior diameter of the RIJV 2.2 mm, and the distance from the skin-RIJV 3.6 mm. In LBW newborns, the median anteroposterior diameter of RIJV was 2.7 mm; in LBW newborns 2.2; in ELBW newborns 1.9 (p < 0.001); the median distance from skin to RIJV for LBW newborns was 4.1 mm; for VLBW newborns, 3.6 and for ELBW newborns 2.9 (p < 0.01); differences that were statistically significant.

CONCLUSIONS

In low birth weight newborns, the diameter and depth of the RIJV is directly proportional to the weight of the subjects studied.

摘要

目的

通过超声测定低出生体重新生儿右颈内静脉（RIJV）的尺寸和深度，评估体重差异并确定该静脉与颈动脉的关系。

方法

我们对100例低出生体重新生儿进行了RIJV的血管评估。受试者分为三组，低出生体重（LBW）新生儿，<2500g；极低出生体重（VLBW）新生儿，<1500g；以及超低出生体重（ELBW）新生儿<1000g。

结果

新生儿中，39%为LBW，33%为VLBW，28%为ELBW。中位数为胎龄31周，体重1300g，RIJV前后径2.2mm，皮肤至RIJV距离3.6mm。在LBW新生儿中，RIJV前后径中位数为2.7mm；VLBW新生儿中为2.2mm；ELBW新生儿中为1.9mm（p<0.001）；LBW新生儿皮肤至RIJV的中位数距离为4.1mm；VLBW新生儿为3.6mm，ELBW新生儿为2.9mm（p<0.01）；差异具有统计学意义。
