Umbilical vascular catheters designed for insertion in an umbilical vein and are long enough to advance and locate their distal tip in a central vein, usually the inferior vena cava or the inferior vena cava right-atrial junction. These catheters typically consist of a silicone elastomer (silastic) or polyurethane single- or double-lumen tube about 30 cm (12 inches) in length and 5 Fr in diameter. Central venous umbilical catheters are used for quick central venous access in critically ill neonates for emergency infusions, exchange transfusions, or central venous pressure monitoring.
