A venous catheter named after Dr. Stanley Shaldon which is inserted under local anaesthesia via the internal jugular vein into the superior vena cava.
A Shaldon catheter can be used as a temporary measure for dialysis when a functional dialysis shunt is not available.
However, it can also be used to apply larger amounts of fluid intravenously in "poor" peripheral veins. A Shaldon catheter must always be blocked with citrate or heparin to prevent thrombosis.
