Patients may be on TPN for many weeks or months until their issues resolve. Throughout the course of therapy, patients may or may not be able to ingest anything orally; whatever the case, they will not get any substantive nutrition via the oral route.
Because patients are not getting any other true form of nutrition, the TPN formula needs to contain all of the essential nutrients a body needs to be healthy. This includes proteins, carbohydrates, fats, electrolytes, vitamins, and minerals. There are standard formulations that are available, and these are often what are used by large hospital systems.
Infusion Solutions, however, batches each TPN formula to meet the individual dietary needs of the patient. This leads to optimal nutrition and a better chance of restoring health. The TPN formula is monitored by the Infusion Solutions team, including pharmacists, nurses, and dieticians.
The formula can be adjusted as necessary based on lab markers and the progress of the disease state. The rate of TPN administration can also be changed under some circumstances.
