Is TPN preferred to be given via central line?

Total Parenteral Nutrition (TPN) is indeed preferred to be given via a central line for several reasons. When patients require TPN, they are receiving essential nutrients intravenously due to an inability to consume them through the gastrointestinal tract. Central lines allow for the administration of hypertonic solutions, which contain high concentrations of glucose and other nutrients that could cause irritation to smaller peripheral veins.

Using a central line minimizes the risk of thrombophlebitis, placement difficulties, and complications associated with administering TPN over long periods. Moreover, central lines can accommodate the larger volume of fluid needed for TPN, which is crucial for maintaining the patient's nutritional status. In summary, the central route is preferred for delivering TPN because it effectively manages the risks associated with high-osmolarity solutions, ensuring patient safety and comfort during nutritional therapy.
