What Is Deep Vein Catheterization For CRRT?

Deep vein catheterization is a method of inserting a special puncture tube through the skin and leaving it in the deep vein (femoral vein, subclavian vein, internal jugular vein) for fluid replacement, treatment and monitoring. Commonly used deep vein catheters for CRRT mainly include the internal jugular vein, subclavian vein and femoral vein, which are important pathways for CRRT treatment.
