[Intracavitary electrocardiogram during the insertion of peripherally inserted central catheters].

OBJECTIVE

To evaluate the applicability, feasibility and accuracy of the IC-ECG with column of saline technique for verifying the final tip position of peripherally inserted central catheters (PICC) by specialist nurses.

METHOD

A total of 99 consecutive PICC were inserted. Patients with no superficial ECG P wave, atrial fibrillation, or a pacemaker were excluded. The IC-ECG technique was performed on 84 patients. A chest x-ray was performed after insertion in all cases, in order to compare images with IC-ECG.

RESULTS

The technique showed an applicability of 84.4%, an feasibility of 88%, and an accuracy of 87.8%.

CONCLUSIONS

The IC-ECG technique for verification of catheter PICC tip locations with column of saline is easy to apply, is cost-effective, is achievable by nurses, and does not involve any risk for patients. The technique involves a learning curve, and it must be performed by qualified health care professionals. The technique is performed during the insertion of the catheter, so verification of the tip is made in situ. It reduces future re-insertions due to wrong positioning of the tip.
