What you should know about Vascular Access

Who Needs Vascular Access?

Individuals who require frequent or sustained medical treatments, such as dialysis, often need vascular access. In the context of dialysis patients, vascular access serves as a lifeline for the successful execution of hemodialysis. It provides a point of entry to the bloodstream and facilitates the continuous flow of blood from the patient to the dialysis machine, allowing for the efficient removal of waste products and excess fluids.

How Should I Prepare For Vascular Access?

Prepare for vascular access by consulting with your healthcare provider to understand the procedure and any specific instructions. Follow pre-procedure guidelines, including fasting if required, and inform your provider about medications. Maintain good hygiene at the access site, wear comfortable clothing, and address any concerns by asking questions during the consultation.

How Is Vascular Access Done?

Our doctor will create an Arteriovenous Fistula (AVF) through a surgical procedure, which involves the following steps: 

1. Preparation: The patient is positioned comfortably, and the surgical site is cleaned and sterilised. Local anaesthesia is administered to numb the area where the incision will be made.

2. Incision: The surgeon makes a small incision at the selected site, often in the upper limb. The incision provides access to the artery and vein chosen for the fistula creation.

3. Arterial and Venous Exposure: The surgeon exposes the chosen artery and vein using delicate surgical techniques.

4. Connection: The surgeon creates a direct connection between the artery and vein. In some cases, a synthetic graft may be used to facilitate the connection.

5. Closure: Once the connection is established, the surgeon closes the incision with stitches or surgical glue.

6. Maturation Period: The patient undergoes a maturation period during which the AVF strengthens and enlarges, allowing it to handle the flow of blood required for dialysis.

The surgical procedure is generally outpatient, meaning patients can often go home the same day.

How Do I Care For My Vascular Access?

Caring for your vascular access involves several key practices to ensure its health and functionality:

• Keep it Clean: Practise good hygiene by regularly cleaning the access site with mild soap and water. Avoid using harsh chemicals or alcohol-based products.

• Inspect for Signs of Infection: Regularly check the access site for redness, swelling, warmth, or any signs of infection. Report any unusual changes to your healthcare provider promptly.

• Protect from Trauma: Take precautions to prevent trauma or injury to the access site. Avoid tight clothing, jewellery, or activities that may put a strain on the access area.

​

• Stay Hydrated: Maintain good hydration, as this supports healthy blood flow and can contribute to the overall well-being of your vascular access.
