Introduction
Hemodialysis patients should take the following precautions regarding their arteriovenous fistula: ensure the wound area is clean and sterile to prevent infection; regularly check for adequate blood flow to avoid blockage; keep the arm with the fistula warm and avoid lifting heavy objects, measuring blood pressure, or performing blood transfusions on that arm; and slightly elevate the arm as needed while ensuring dressings are not too tight.
Generally, arteriovenous fistula care for hemodialysis patients includes maintaining hygiene, regularly checking blood flow, and avoiding lifting heavy objects. The details are as follows:
1. Maintain Hygiene
During dialysis, hemodialysis patients require a vascular access—known as an arteriovenous fistula—to facilitate efficient blood drainage. It is essential to keep the surgical site clean and sterile during this period to prevent infection.
2. Regularly Check Blood Flow
After fistula creation, patients should routinely monitor blood flow to ensure patency and avoid complications such as blockage or occlusion.
3. Avoid Lifting Heavy Objects
The arm with the fistula should be kept warm and protected from strenuous activities such as lifting heavy items. Additionally, blood pressure measurements and intravenous procedures should not be performed on this arm.
In addition to the above common precautions, patients should appropriately elevate the arm, avoid overly tight dressings, apply proper pressure at the puncture site, follow medical advice regarding medication, maintain a light diet, limit fluid intake, manage body weight appropriately, and continuously monitor for signs of bleeding. If any discomfort or abnormalities occur, prompt medical attention is necessary.
