Glossary Entry: Triple Lumen Catheter


Definition: A triple lumen catheter is a type of intravenous catheter with three separate channels, allowing for the simultaneous administration of multiple medications or fluids, as well as the monitoring of central venous pressure.

Detailed Description

Types and Variations

Variations: There are different sizes and materials available for triple lumen catheters, with variations in length and gauge to accommodate different patient needs.


Common Uses: Triple lumen catheters are commonly used in critically ill patients who require multiple intravenous medications or fluids, as well as in situations where frequent blood draws or hemodynamic monitoring is necessary.

Insertion and Placement

Procedure: The triple lumen catheter is typically inserted using the Seldinger technique, and proper placement is confirmed via X-ray or ultrasound. Careful attention must be paid to the insertion site and angle to prevent complications such as pneumothorax or arterial puncture.

Clinical Considerations

Potential Complications

Risks: Risks associated with triple lumen catheters include infection, thrombosis, air embolism, and catheter malposition.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the catheter include sterile dressing changes, regularly flushing the lumens with heparinized solution, and monitoring for signs of infection or dislodgment.
