The picture is as above, the professional term is central venous catheterization through peripheral venous puncture.
Central venous catheterization through peripheral venipuncture:
Central venous catheterization through peripheral venous puncture uses a catheter to puncture the veins of the peripheral arm, and the catheter goes directly to the large veins close to the heart. , to avoid direct contact between chemotherapy drugs and arm veins. In addition, the blood flow rate of large veins is very fast, which can quickly dilute chemotherapy drugs and prevent drugs from irritating blood vessels.
Therefore, it can effectively protect the veins of the upper limbs, reduce the occurrence of phlebitis, relieve the patient's pain, and improve the patient's quality of life.
Introduction:
If you use a PICC, be careful not to move your arms too much or too violently during use to prevent the catheter from falling off or breaking; in addition, do it once a week Flush the tube and change the film (completed by the nurse). Try to use a shower when bathing. If the film is loose, replace it in time to prevent obstruction of the catheter or infection of the skin blood vessels where the catheter is inserted. If the PICC is well maintained, it can generally be used for more than 1 year, which is enough to last until the end of chemotherapy.
1. Vein selection
PICC catheterization is usually done in the basilic vein of the patient’s cubital fossa, the median cubital vein, or the cephalic vein, and the catheter is directly inserted into the superior vena cava. . It is necessary to choose blood vessels with good elasticity and exposure.
2. Indications for PICC catheterization
(1) Those who require long-term intravenous infusion, but the condition of peripheral superficial veins is poor and it is difficult to puncture successfully;
( 2) Need to repeatedly inject irritating drugs, such as chemotherapy drugs;
(3) Long-term infusion of drugs with high permeability or high viscosity, such as high sugar, fat emulsion, amino acids, etc.;
(4) Those who need to use pressure or pressurized pumps for rapid infusion, such as infusion pumps;
(5) Those who need to repeatedly infuse blood products, such as whole blood, plasma, platelets, etc.;
(6) Those who require multiple venous blood tests every day.
