What is the correct procedure for using a C-clamp on an arteriotomy site?

Using a C-clamp on an arteriotomy site is an important technique in interventional radiology, primarily aimed at achieving hemostasis. The correct procedure involves placing a sterile disc at the arteriotomy site before lowering the clamp onto it. This approach ensures that the clamp exerts pressure directly on the sterile dressing rather than directly on the skin or the vessel, which could cause tissue damage or contamination.

By using a sterile disc, you create a barrier that helps protect the site from infection and allows for adequate pressure application without compromising the surrounding tissue. This method also aids in ensuring that the pressure is evenly distributed across the site, which is crucial for effective hemostasis.

Inappropriate use of the clamp, such as tightening it excessively without appropriate release, can lead to complications such as tissue necrosis. Therefore, it is vital to follow best practices when applying a C-clamp to ensure patient safety and optimal outcomes.
