Child fitted with dialysis catheter. Double-lumen jugular vein catheter being used on a young boy. Such double catheterization of the internal jugular vein is usually done to carry out short-term haemodialysis to treat kidney disorders. The arterial catheter (red) withdraws blood to the dialysis machine, while the venous lumen (blue) returns blood from the dialysis machine. Kidney dialysis (haemodialysis) is used for those with reduced or failing kidney function. A machine is used to remove waste and excess water from the blood, a function normally served by the kidneys. Photographed in India.
