Intravenous news: News Medical report ” Parenteral nutrition safety: an interview with Dr. Phil Ayers, A.S.P.E.N PN Safety Task Force Chair and Dr. Peggi Guenter, Director of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.). Please can you give a brief introduction to parenteral nutrition (PN)?
Parenteral nutrition is intravenous nutrition for patients who are unable to eat or be tube fed. It is used with more than 300,000 patients per year – a quarter of whom are children and newborns.
PN bypasses the normal digestion in the stomach and bowel. It is a sterile liquid formula given into the blood through an intravenous (IV) catheter (needle in the vein). The mixture contains proteins, carbohydrates (sugars), fats, vitamins and minerals (such as calcium).
People of all ages have received parenteral nutrition. People can live well on parenteral nutrition for as long as it is needed. Many times, parenteral nutrition is used for a short time; then it is removed when the person can begin to eat normally again.
