The electrocardiographic method for positioning the tip of central venous access device
1Department of General Surgery, HwaMei Hospital, University of Chinese Academy of Sciences, Ningbo, China.
Background:
The electrocardiogram-based insertion method is non-radiative, allowing real-time positioning verification and reducing the need for postoperative repositioning.
Methods:
Relevant databases published from January 1990 to January 2019 in PubMed, Web of Knowledge, Medline and Ovid's database were searched, comparing the effectiveness of electrocardiogram-guided catheter tip positioning (electrocardiogram-guided group) and the landmarks-guided insertion plus chest X-ray confirmation (landmarks-guided group). The primary outcome was accurate catheter tip placement and the secondary outcomes were complications.
Results:
A total of 13 studies were finally included with a total of 4988 patients, of whom 2789 cases were in the electrocardiogram-guided group and 2199 cases received landmarks-guided insertion plus chest X-ray. Compared with the landmarks-guided group, our meta-analysis showed that the electrocardiogram-guided group had a higher success rate of tip placement (odds ratio = 0.21, 95% confidence interval = 0.14-0.34, p < 0.00001) and fewer total complications (odds ratio = 0.10, 95% confidence interval = 0.04-0.23, p < 0.000001).
Conclusion:
Based on our findings, electrocardiogram-guided tip placement for central venous access device was more accurate and safer than landmarks-guided positioning, which may be considered as an alternative method to the standard radiological control of tip placement.

Central venous access devices (CVAD), commonly known as central lines or central catheters, are large-bore intravenous (IV) catheters that are introduced into the central circulation. Typically, CVADs terminate in the superior vena cava, just outside of the right atrium of the heart, but they may also terminate in any one of the great veins (i.e., aorta, inferior vena cava, brachiocephalic...

Central venous access is necessary in a multitude of clinical situations for hemodynamic monitoring, medication delivery, and blood sampling. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the femoral vein.
Central venous access via the subclavian vein has several advantages over other possible locations. The subclavian...
