Glossary Entry: Temporary Dialysis Catheter


Definition: A temporary dialysis catheter is a medical device used to provide access for temporary hemodialysis or hemofiltration. It is designed to facilitate the removal and return of blood during the dialysis process.

Detailed Description

Types and Variations

Variations: Temporary dialysis catheters can vary in size and design, with options for single-lumen or dual-lumen configurations. The specific variation chosen depends on the patient’s individual needs and the planned duration of dialysis.


Common Uses: Temporary dialysis catheters are commonly used in emergency situations where immediate dialysis is required, in critically ill patients who do not have a functioning permanent access, or as a bridge to a more permanent access solution.

Insertion and Placement

Procedure: The insertion of a temporary dialysis catheter involves careful placement into a central vein, often the jugular or femoral vein, under sterile conditions. The correct placement and securement of the catheter are essential to prevent complications such as infection or dislodgement.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with temporary dialysis catheters include infection, thrombosis, and catheter dislodgement. Careful monitoring and maintenance are necessary to minimize these risks.

Care and Maintenance

Maintenance Requirements: Regular flushing of the catheter with heparinized saline and meticulous dressing changes are essential to prevent infection and maintain optimal catheter function.

Additional Information

Related Devices

Associated Terms: Accessories often used in conjunction with temporary dialysis catheters include extension tubing, catheter securement devices, and catheter locking solutions.

Innovations and Advancements

Recent Developments: Recent advancements in temporary dialysis catheter design have focused on reducing infection rates and improving ease of insertion, such as antimicrobial catheter materials and improved catheter tip designs.

Regulatory and Safety Notes

Regulations: Temporary dialysis catheters are regulated medical devices, and their use must comply with relevant safety and performance guidelines as mandated by regulatory authorities.
