Glossary Entry: Peritoneal Dialysis Catheter

Overview

Definition: The peritoneal dialysis catheter is a flexible tube surgically implanted into the abdomen to facilitate peritoneal dialysis, a treatment for kidney failure. It allows for the infusion of dialysis solution into the peritoneal cavity and the drainage of waste products and excess fluid.

Detailed Description

Types and Variations

Variations: There are different types of peritoneal dialysis catheters, including straight catheters and coiled catheters, each with specific applications based on patient anatomy and medical history.

Indications

Common Uses: Peritoneal dialysis catheters are commonly used in patients with end-stage renal disease who opt for peritoneal dialysis as their preferred method of renal replacement therapy.

Insertion and Placement

Procedure: The peritoneal dialysis catheter is inserted through a small incision in the abdomen and placed into the peritoneal cavity. Specific techniques such as the Seldinger technique may be used for precise placement.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with peritoneal dialysis catheters include infection, catheter malfunction, and leakage of dialysis solution.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the catheter include regular cleaning, monitoring for signs of infection, and following sterile techniques for dialysis exchanges.

Additional Information

Related Devices

Associated Terms: Peritoneal dialysis catheters may be used in conjunction with peritoneal dialysis solution bags, transfer sets, and sterile connection devices.

Innovations and Advancements

Recent Developments: Recent advancements in peritoneal dialysis catheter technology include the development of catheters with improved flow characteristics and reduced risk of infection.

Regulatory and Safety Notes

Regulations: The use and placement of peritoneal dialysis catheters are subject to regulatory guidelines and safety considerations to ensure patient well-being during peritoneal dialysis treatment.
