Glossary Entry: Seldinger Technique

Overview

Definition: The Seldinger Technique is a medical procedure used for gaining access to blood vessels or other hollow organs by using a needle and guidewire to facilitate the insertion of catheters or other medical devices.

Detailed Description

Types and Variations

Variations: The Seldinger Technique has variations for accessing different types of vessels and organs, such as central venous access, arterial access, and percutaneous nephrostomy.

Indications

Common Uses: This technique is commonly used for procedures such as central venous catheterization, arterial catheterization, and percutaneous drainage of fluid collections.

Insertion and Placement

Procedure: The Seldinger Technique involves the insertion of a needle into the vessel or organ, followed by the insertion of a guidewire through the needle. Once the guidewire is in place, the needle is removed, and a catheter or other device can be threaded over the guidewire and into the vessel or organ.

Clinical Considerations

Potential Complications

Risks: Potential complications of the Seldinger Technique include bleeding, hematoma formation, infection, and vessel or organ perforation.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the inserted catheter or device are essential to prevent complications such as catheter-related bloodstream infections and thrombosis.

Additional Information

Related Devices

Associated Terms: Devices commonly used in conjunction with the Seldinger Technique include central venous catheters, arterial catheters, and nephrostomy tubes.

Innovations and Advancements

Recent Developments: Innovations in the Seldinger Technique include the use of ultrasound guidance for vessel access, which has improved safety and success rates.

Regulatory and Safety Notes

Regulations: The use of the Seldinger Technique and related devices is subject to regulatory guidelines and safety considerations to ensure patient safety and proper procedural execution.
