Hemodialysis Catheter Insertion

Hemodialysis Catheter Insertion in Bathinda

Hemodialysis is a life-saving treatment for individuals with advanced chronic kidney disease (CKD) where their kidneys can no longer effectively remove waste products and excess fluid from the blood. Hemodialysis relies on vascular access, a reliable point of connection to the bloodstream, to allow for blood withdrawal and return during treatment sessions. Catheter insertion is a common method for establishing vascular access for hemodialysis, offering both temporary and permanent options.

Vascular Access for Hemodialysis:

There are three main types of vascular access for hemodialysis:

Arteriovenous (AV) fistula: A surgically created connection between an artery and a vein, allowing for high blood flow rates. This is the preferred long-term access option due to its durability and lower infection risk.
Arteriovenous (AV) graft: A synthetic tube used to connect an artery to a vein when creating a fistula is not possible due to unsuitable veins.
Hemodialysis catheter: A temporary or permanent access point placed in a large vein for blood withdrawal and return during hemodialysis sessions.

Types of Hemodialysis Catheters:

There are two main types of hemodialysis catheters, each with its own purpose and placement:

Temporary Catheter:
- Used for short-term access (typically less than 3 weeks) until a permanent access point like an AV fistula matures.
- Placed in a large vein in the neck (jugular) or groin (femoral).
- Typically made of soft polyurethane material.
- Requires meticulous care and sterile technique to minimize infection risk.
Permanent Catheter (Permcath):
- Also known as a tunneled cuffed catheter.
- Used for long-term access (months to years) when creating an AV fistula or graft is not ideal or immediate dialysis is needed.
- Placed in a large vein in the chest (subclavian or jugular).
- Features a tunnel under the skin from the insertion site to the exit point, reducing infection risk compared to non-tunneled catheters.
- Has a cuff under the skin to secure the catheter in place.

The Hemodialysis Catheter Insertion Procedure:

Both temporary and permanent catheter insertions are typically performed as outpatient procedures under local anesthesia with sedation. Here’s a general overview:

Preparation: You may be asked to stop taking certain medications beforehand.
Catheter Placement:
- For temporary catheters, the doctor inserts the catheter directly into the vein using a needle and guidewire.
- For permanent catheters, a small incision is made near the collarbone or chest, the catheter is tunneled under the skin, and the tip is inserted into the vein. The exit point of the catheter is secured with sterile dressings.
Recovery: Following the procedure, you will be monitored for a few hours to ensure there are no complications. Most people can go home the same day with specific instructions on catheter care.

Benefits and Considerations of Catheter Insertion

Temporary Catheters:
- Benefits: Provides immediate vascular access for hemodialysis initiation while waiting for a permanent option.
- Considerations: Higher infection risk, less comfortable for long-term use, and may limit blood flow rates compared to AV fistulas.
Permanent Catheters (Permcath):
- Benefits: Provides long-term access for hemodialysis, offers more flexibility compared to temporary catheters, and allows for easier blood flow compared to some temporary catheters.
- Considerations: Higher infection risk compared to AV fistulas, requires ongoing care and monitoring of the exit site, and may not be suitable for everyone.

Who is a Candidate for Hemodialysis Catheter Insertion?

The decision to use a temporary or permanent catheter depends on your individual situation and needs. Your nephrologist will consider factors like:

Urgency of starting hemodialysis
Suitability for creating an AV fistula or graft
Overall health and presence of other medical conditions
Patient preference
