TPN : Tpn (total parenteral nutrition) is a way of providing a person's nutrition directly into the blood through an iv. Part of what makes up the solution is glucose or sugar which is a very important nutritional need for organs such as the brain and heart. Tpn usually also has proteins, fats, electrolytes, vitamins and minerals - basically everything a person needs. Since you are pumping sugar via TPN directly into the blood and bypassing the gut, you lose out on the gut's fantastic ability to regulate the sugar and other nutrients entering the blood. Therefore, frequent blood glucose, protein, fat and electrolyte checks (especially when starting tpn) are very important to make sure the TPN solution does not have too much or too little of any one nutrient. Doctors and nutritionists usually start out with a specific amount according to a person's weight and age, but since everyone's a little different, TPN usually needs to be tweaked multiple times for the best result.

TPN: Tpn is a solution with high glucose content and blood sugar should be monitored to prevent hyperglycemia.
