Your child's blood will tell the nutritional support team which nutrients your child needs. The total parenteral nutrition (TPN) solution comes mixed in a bag. It is given to your child like a regular IV (an IV that keeps your child hydrated by giving him or her fluids). A catheter (or small tube) will be placed in one of your child's main blood vessels. It may be in his or her neck, chest, leg, or groin.
