The aim of our study is to compare two ECG techniques for guiding Peripherally Inserted Central Venous Cather (PICC) in terms of accuracy of the final position of the catheter tip.
One technique uses ECG signal transmission with saline water and allows external catheter length adjustment while the other technique uses a guidewire for signal transmission thus requiring prior catheter length adjustment

| LifeCath-CT PICC easy™ (Vygon) | Device | ECG electrodes are placed on patient's chest ensuring that there is a distinguishable P-wave. Upper arm selection is based on vein diameter and dominance, ultrasound is used to identify a suitable vein. The patient is prepared using a maximal sterile barrier approach. The catheter is inserted into one of the veins (75-90° arm abduction) using ultrasound and modified Seldinger technique. The PICC is advanced into the central circulation and used as an intracavitary electrode (connection with Vygocard2™). Saline water instilled through the catheter ensures conductivity. The ECG is then used until displayed intracavitary P-wave has a maximal height without negative deflexion. Catheter is left at this point (cavo atrial junction). The PICC hub side is then trimmed and the catheter part connected. The PICC is caped with a neutral bidirectional valve. The puncture site is dressed and catheter stabilized. Chest Xray is obtained immediately after insertion to assess the position. |
| Measure | Description | Time Frame |
|---|---|---|
| Distance from catheter tip to cavo-atrial junction (CAJ) | At the end of intervention tip position is measured on chest fluoroscopic X-ray. Absolute distance in centimeters from tip to CAJ is measured on the image | At the end of intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Length of the outgoing catheter | Length of the outgoing catheter at the entry point near the bend of the elbow in centimeters | At the end of intervention |
| Haemostasis time | Haemostasis time at the puncture site entry point (0, 1, 3, 5, >5 minutes) |

| PowerPICC-SOLO® (C.R. Bard) | Device | ECG electrodes are placed on patients chest ensuring that there is a distinguishable P-wave. Upper arm selection is based on vein diameter and dominance, ultrasound is used to identify suitable vein. The patient is prepared using a maximal sterile barrier approach. The catheter is inserted into one of the veins (75-90° arm abduction) using ultrasound and modified Seldinger technique. The catheter's free end is cut to the anticipated length using anthropometric measurements (insertion/axillary crease+axillary crease/sternal notch+13cm) and the preloaded magnetic-tipped stylet (serving as intracavitary electrode) is put inside. The PICC is advanced into central veins until intravascular ECG displays a P-wave with maximal height without negative deflexion. Catheter is left at this point (cavo atrial junction). The puncture site is dressed and catheter stabilized. Chest Xray is obtained immediately after insertion to assess position. |
