目的：探讨心内心电图定位技术在 PICC 导管头端定位的临床应用效果。方法选取我科2013年10月～2014年12月收治的115例置入 PICC 患者作为研究对象，所有患者均按统一的程序完成置管，并在置管过程中运用心内心电图定位技术对 PICC 导管头端定位，置管后再次行 X 线拍片定位。结果心内心电图对 PICC 头端进入上腔静脉的灵敏度为93．03％，108例患者出现特征性 P 波，7例无 P 波变化；X线片显示108例导管头端位于上腔静脉内，2例在锁骨下静脉内（2例静脉走向打圈，导致导管在静脉内打圈长度不足，未到达上腔静脉），2例在颈静脉内，3例在肱静脉内。结论对 PICC 导管头端定位采取心内心电图定位技术，具有较高的灵敏度与特异度，可临床推广应用。

Objective The intracardiac electrocardiogram (ecg) positioning technology in the clinical appli -cation of PICC catheter tip to locate effect were discussed .Methods 115 cases of our department in October 2013-2014 December PICC placement of patients admitted to the study .All patients completed according to uniform pro -cedures catheter, and the use of intracardiac electrocardiogram positioning technology in the catheterization process PICC catheter tip positioning, again catheter positioning X -ray film.Results Intracardiac electrocardiogram PICC tip into the superior vena cava sensitivity of 93.03%, and the situation is a total of seven cases no P wave changes , the rest of the patient P or T wave changes .X -ray showed 108 cases of catheter tip is located on the within the vena cava, and two cases in the subclavian vein (intravenously to two cases of circular motion , resulting in a circular mo-tion intravenous catheter insufficient length , which does not reach the superior vena cava ), and two cases in the inter-nal jugular vein, three cases in the brachial vein .Conclusion PICC catheter tip positioning taking intracardiac elec -trocardiogram positioning technology , with high sensitivity and specificity , which can be clinical application .
