The effect of abduction and adduction of the arm on the position of central venous catheters inserted via cubital veins was studied in 41 surgical patients. The location of the catheter tip and the abduction-adduction angle were measured from x-ray pictures. With adduction, the catheter always advanced inwards, the maximal movement being 9.5 cm. The average displacement varied from 2.0 cm to 3.3 cm and there was a statistically significant correlation (P less than 0.001; r = 0.831) between the advancement of the catheter tip and the abduction-adduction angle. There was no correlation between tip displacement and change in central venous pressure.
对41例外科手术患者研究了手臂外展和内收对经肘静脉插入中心静脉导管位置的影响。通过X光片测量导管尖端的位置和外展-内收角度。在内收时，导管总是向内推进，最大移动距离为9.5厘米。平均移位在2.0厘米至3.3厘米之间，导管尖端的推进与外展-内收角度之间存在统计学显著相关性（P<0.001；r=0.831）。尖端移位与中心静脉压变化之间无相关性。
