17、.MATERIALS AND METHODS The catheters were inserted in the brachial or basilic veins under ultrasonographic guidance with the upper extremity in a 90 abducted position. A flexible, radiopaque ruler wasthen placed on the anterior chest and digital images were obtained with the arm abducted and adducte

18、d in a similar phase of quiet respiration.

19、om the right arm and 20 from the left. Overall, 43 moved caudally, seven moved cephalad, and three did not move with movement of the arm from abduction toadduction. Of those that moved caudal, the mean distance of movement was 21 mm (range, 253 mm). Right arm PICCs tended to move more than left arm

20、PICCs, but this did not attain significance (P = .29).CONCLUSIONS There is a tendency for the PICC tip to move in a caudal direction with the change in arm position from abduction to adduction; 58% of PICCs moved 20 mm or more. This change in position should be considered during final catheter tip positioning.2021/7/16 星期五41PICC 導(dǎo)管置入的導(dǎo)向方法透視導(dǎo)引放置導(dǎo)管頭端能夠隨時(shí)調(diào)整到位性價(jià)比差床邊PICC后胸片位置不正確，調(diào)整后（blindly)再胸片簡便Which will be more advantageous2021/7/16 星期五42床邊PICC插管成功率研究對象：兒童,平均6.9歲介入手術(shù)
