We hypothesized that placing the arm in 90° abduction, through 90° flexion and 90° external rotation, could improve ultrasound visualization of the subclavian vein. In 49 healthy volunteers, a single operator performed a view of the subclavian vein in neutral position and abduction position. A second blinded operator measured the cross-sectional area of the subclavian vein. Abduction position increased the cross-sectional area of the subclavian vein from 124 ± 46 (mean ± SD) to 162 ± 58 mm (P = 0.001). An increase of the cross-sectional area of ≥50% was observed in 41% volunteers (95% confidence interval, 27%-56%, n = 20); this technique offers an alternative approach (maybe safer) for ultrasound-guided catheterization of the subclavian vein.
我们推测，将手臂置于90°外展、90°屈曲和90°外旋位，可改善锁骨下静脉的超声可视化。在49名健康志愿者中，由一名操作者对锁骨下静脉在中立位和外展位进行观察。另一名不知情的操作者测量锁骨下静脉的横截面积。外展位使锁骨下静脉的横截面积从124±46（平均值±标准差）增加至162±58 mm²（P = 0.001）。41%的志愿者（95%置信区间，27%-56%，n = 20）观察到横截面积增加≥50%；该技术为锁骨下静脉超声引导下置管提供了一种替代方法（可能更安全）。
