Peripherally Inserted Central Catheter (PICC) is a thin flexible tube that is inserted into a vein upper arm and guided into a large vein above the right side of the heart called the superior vena cava. It is used to give intravenous fluids, blood transfusions, chemotherapy, etc…
PICCs are inserted by ultrasound-guided puncture and cannulation of the deep upper arm veins (most often the basilic or brachial vein) via the modified Seldinger technique (venipuncture with a small-gauge needle, insertion of a thin guidewire through the needle, removal of the needle, insertion of a micro-introducer-dilator over the guidewire, removal of the wire and dilator, insertion of the catheter through the introducer).
This technique facilitates the catheterization of large-bore veins of known diameter and trajectory while allowing positioning of the exit site in the upper part of the arm (halfway between the elbow and the axilla).
As a final result, the rate of insertion failure is minimal, insertion-related complications are almost negligible, the exit site is handled easily by patients and nursing staff, and the rate of late complications (infection, catheter-related venous thrombosis, dislocation) is low.
The High-frequency Mini-Linear Handheld Wi-Fi Ultrasound Scanner MLCD is highly recommended to Anesthesiologists, Radiologists, Radiology physician assistants, and Nurses.
Ultrasound-guided puncture is most commonly performed via an “out-of-plane” approach (the needle trajectory does not lie in the transducer plane).
When the transducers are equipped with a needle holder, it facilitates puncture.
Moreover, When using ultrasound for venipuncture, position the ultrasound handheld probe (also called a transducer) on the skin to produce either transverse or sagittal images of veins.
When you position the probe perpendicular to a vein, the vein appears as a circle on the ultrasound monitor screen; this is a transverse view.
Placing the probe parallel to the vein produces a sagittal (longitudinal) view of the vein.
