摘要：

目的　探讨经食管超声技术（TEE）不同径路行婴幼儿中心静脉导管穿刺定位的可行性及临床应用价值。　方法　选择择期行心血管手术的婴幼儿100例，共分两个径路,右颈内静脉以及右锁骨下静脉径路。每个径路各为50例，其中每个径路里25例采用经食道超声技术定位中心静脉导管置入的深度，25例根据身高年龄以及体重确定中心静脉导管的置入深度，并与胸部X线相应胸椎水平进行对比。　结果　所有中心静脉导管经TEE定位后管尖位置均能准确的定位于第4胸椎（T4）与第6胸椎（T6）水平之间。　结论　TEE可以为婴幼儿中心静脉管的定位提供一个客观、直接的定位标准。

Abstract:

Objective　 To explore the values of transesophageal echocardiography in determining optimal depth of insertion of CVP catheter in infants undergoing cardiovascular surgery.　Methods　100 infants underwent cardiovascular surgery were selected in this study. The CVP catheterization was performed under the guide of TEE. The position of the catheter tip determined by AP chest x-ray, was identified by the level of thoracic vertebra(T) corresponding to the position of the catheter tip.　Results　The position of tip normally distributed from T4-T6 which anatomically corresponded to SVC under the guide of TEE. Conclusions　TEE is a simple and accurate guide for positioning the catheter tip at the level of T4-T6 in infants.
