INTRACARDIAC ELECTROCARDIOGRAM (ECG) POSITIONING TECHNOLOGY APPLICA-TION RESEARCH OF PLCC CATHETER TIP TO POSITIONING / 现代医院

ABSTRACT

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 .
