Background technique

In the process of tumor treatment, puncture surgery is required. PICC catheterization is also called peripheral venous puncture central venous catheterization. It uses a catheter to puncture from a vein in the peripheral arm. The catheter goes directly to the large vein close to the heart, avoiding the interaction between chemotherapy drugs and arm veins. Direct contact, coupled with the fast blood flow of large veins, can quickly dilute chemotherapy drugs and prevent drugs from stimulating blood vessels, so it can effectively protect the veins of the upper limbs, reduce the occurrence of phlebitis, reduce the pain of patients, and improve the life of patients. quality. The general operation method is to take the patient in the supine position, and use a tape measure to measure the length of the patient from the puncture site to the superior vena cava, which is generally 45-48 cm. After selecting the puncture site, tie a tourniquet, perform routine disinfection, and perform PICC catheter venipuncture according to the instructions. The length of the catheter is reserved according to the patient's condition, and X-rays are taken after the puncture is completed, and it can be used after confirming that it is in the superior vena cava.
