Glossary Entry: Hemodialysis Catheter

Overview

Definition: A hemodialysis catheter is a tube inserted into a large vein, usually in the neck or groin, to provide temporary vascular access for hemodialysis.

Detailed Description

Types and Variations

Variations: Hemodialysis catheters come in single-lumen and dual-lumen variations, with the dual-lumen catheter allowing for simultaneous withdrawal of blood for filtration and return of filtered blood to the body.

Indications

Common Uses: Hemodialysis catheters are commonly used in patients with acute kidney injury, patients with end-stage renal disease who require immediate dialysis access, and in those awaiting placement of a more permanent access such as an arteriovenous fistula or graft.

Insertion and Placement

Procedure: The insertion of a hemodialysis catheter involves aseptic technique and may require the use of ultrasound guidance. Proper placement is crucial to avoid complications such as thrombosis or infection.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with hemodialysis catheters include infection, thrombosis, and catheter dysfunction.

Care and Maintenance

Maintenance Requirements: Regular flushing and dressing changes are essential for preventing infection and maintaining catheter patency.

Additional Information

Related Devices

Associated Terms: Related devices may include anticoagulants for preventing clot formation around the catheter and securement devices to prevent catheter dislodgement.

Innovations and Advancements

Recent Developments: Recent advancements in hemodialysis catheter technology include the use of antimicrobial-impregnated catheters to reduce infection risk.

Regulatory and Safety Notes

Regulations: Healthcare facilities must adhere to strict guidelines for the use and maintenance of hemodialysis catheters to ensure patient safety and regulatory compliance.
