long-term TPN

Long-term Total Parenteral Nutrition (TPN) is a method of providing essential nutrients directly into the bloodstream when the digestive system cannot adequately absorb or process food over an extended period. It involves delivering a carefully balanced mixture of carbohydrates, proteins, fats, vitamins, and minerals through a catheter inserted into a large vein. This approach allows the body to receive necessary nutrition, supporting growth, energy, and overall health when oral or tube feeding isn't possible, often used for patients with chronic digestive conditions or those recovering from certain surgeries.
