Dialysis Catheter Insertion is a medical procedure in which a catheter (a thin, flexible tube) is placed into a large vein to provide access to the bloodstream for dialysis treatments. Dialysis is a treatment that filters and purifies the blood using a machine, which helps keep your body in balance when the kidneys can't perform this function.

There are two main types of dialysis catheters:

Central Venous Catheter (CVC):

• Temporary CVC: Inserted into a large vein in the neck (jugular vein), chest (subclavian vein), or groin (femoral vein). It is used for short-term dialysis access.

Peritoneal Dialysis Catheter

• Permanent (Tunneled) CVC: Also inserted into a large vein in the neck or chest, but the catheter is tunneled under the skin to reduce the risk of infection and can be used for a longer duration.

Procedure for Central Venous Catheter Insertion:

• Preparation: The patient is usually given a local anesthetic to numb the insertion area. Sometimes, sedation or general anesthesia is used.
• Insertion: Using ultrasound guidance, a needle is inserted into the vein. A guidewire is threaded through the needle, and the needle is removed. The catheter is then placed over the guidewire and advanced into the vein. The guidewire is removed, leaving the catheter in place.
• Positioning: The catheter is positioned correctly, often confirmed by X-ray.
• Securing: The catheter is secured with sutures and a dressing to keep it in place and reduce infection risk.
