What are the steps for securing a umbilical venous catheter?

The general fixation method for umbilical venous catheterization involves the following seven steps: 1. Before the procedure, examine the patient's skin, especially the area around the catheter insertion site, to determine whether there is any allergy or skin damage; if necessary, perform appropriate skin preparation first; 2. Take an appropriate number of adhesive dressings and gently wipe them with a clean damp towel; 3. Instruct the patient to turn their head to one side and assume a sitting or semi-reclining position; fix the dressing near the left and right sides of the umbilicus to ensure continuous patency of the catheter; 4. Ensure the dressing has good adhesiveness, firmly attach it over the catheter site, and gently wipe with a clean damp towel; 5. Connect the tubing on the dressing to the connector on the catheter device, and check the integrity of all tubing and the security of all connections; 6. Secure the edges of the dressing to the catheter device to ensure stable fixation; 7. Finally, verify the position of the catheter, confirm the stability of the dressing, and document this in the patient's medical record.
