We investigated the effects of head rotation on the cross-sectional area of the right internal jugular vein and its relative position to the carotid artery. Eighty-eight subjects were divided into infants and children groups. The cross-sectional area of the right internal jugular vein and the degree of the carotid artery overlap were measured at 0 degrees (neutral), 40 degrees and 80 degrees of head rotation. The cross-sectional area of the right internal jugular vein was significantly larger at 40 degrees and 80 degrees head rotation compared with the neutral position in both infants and children (p < 0.001). As the head was rotated, the percentage overlap of the carotid artery increased significantly (p < 0.001). We suggest that 40 degrees head rotation appears to be optimal for right internal jugular vein cannulation in paediatric patients.
我们研究了头部转动对右颈内静脉横截面积及其与颈动脉相对位置的影响。88 名受试者被分为婴儿组和儿童组。在头部处于 0 度（中立位）、40 度和 80 度时，测量右颈内静脉的横截面积和颈动脉重叠程度。与中立位相比，婴儿和儿童在头部旋转 40 度和 80 度时，右颈内静脉的横截面积明显增大（p<0.001）。随着头部转动，颈动脉重叠的百分比显著增加（p<0.001）。我们建议，40 度头部旋转似乎是儿科患者行右颈内静脉置管的最佳选择。
