What is the full name of picc?

The full name of picc is peripherally inserted central venous catheterization.

Puncture the central venous catheter through the peripheral vein, and puncture the catheter from the peripheral arm vein directly to the vein near the heart to avoid direct contact between chemotherapy drugs and the arm vein. In addition, the venous blood flow is very fast, which can quickly dilute chemotherapy drugs and prevent drugs from stimulating blood vessels. Therefore, it can effectively protect the veins of upper limbs and reduce the occurrence of phlebitis.

Matters needing attention

When the infusion flow rate allows, PICC catheter with the smallest model, thinnest and smallest lumen should be selected for puncture as much as possible. Complications caused by hemodynamic changes around the thick catheter increase the possibility of phlebitis or vascular obstruction.

Edema appears below the puncture site at any time, but it is not caused by too tight bandages or clothes. It should be considered that the catheter is thicker than the vein, which will affect the venous return and should be the indication of catheter removal.

It is suggested that the indwelling time of catheter should be 8 ~ 12 weeks, and the indwelling time can be decided by the doctor according to the treatment needs. When pulling out the catheter, gently pull it out from the puncture point, immediately press it to stop bleeding, fix it with dressing, change the dressing every 24 ~ 48 hours until the wound heals, measure the length of the catheter, observe whether there is any injury or fracture, and make records.
