What is Parenteral Nutrition?
The provision of “sensible” amounts of nutrients to support the patient until sufficient oral or enteral feeding can be established could be described as the mission statement for TPN therapy. TPN is an essential feature of the modern medical care. It has been for nearly 15 years now that TPN is being given through TNA (Total Nutrient Admixture) or AIO (All in one) admixture with carbohydrates, lipids, and amino acids mixed in a bag and infused continuously over 24 hours.
