ABSTRACT
Objective:
To study electrocardiogram (ECG) monitoring assisted ultrasound guidance for modiifed seldinger technique (MST) in peripherally inserted central catheters (PICC) and to estimate the accuracy of ECG for presenting catheter tip location.Methods:
The patients were connected with ECG monitoring system, the guide wire was connected to RA electrode in ECG monitor for leading out P wave of intracavitary ECG. The location of catheter tip was estimated by P wave characteristics and then, estimated ECG result was further compared with chest X-ray presented catheter tip position. The coherence of catheter tip position between ECG and chest X-ray was compared, the sensitivity and speciifcity of ECG estimation were calculated.Results:
There were 100/104 patients showed speciifc P wave in ECG, the coherence to chest X-ray was 96.2%; 4 patients had no speciifc P wave and their chest X-ray presented that the catheter tip position at upper superior vena cava in 2 patients, at lower superior vena cava in 1 patient, at contralateral brachiocephalic vein in 1 patient. The accuracy of 2 methods had no statistic meaning. ECG estimation for PICC catheter tip position had the sensitivity at 99% and speciifcity at 100%.Conclusion:
ECG monitoring may determine the catheter tip position for MST in PICC guided by ultrasound. It doesn’t need chest X-ray, without additional trauma and no radioactive contamination, which make PICC catheters get more extensive application in clinical practice.
