The medical abbreviation "TPN" stands for "Total Parenteral Nutrition". TPN is a form of nutrition therapy in which all of a person's nutritional needs are met through an intravenous (IV) solution, rather than through oral intake. It is typically used for patients who are unable to eat or absorb nutrients through their digestive system, such as those with severe gastrointestinal disease, bowel obstruction, or malabsorption disorders.
The TPN solution contains a balance of carbohydrates, proteins, fats, vitamins, and minerals, and is administered through a central venous catheter, which is a long, thin tube that is inserted into a large vein in the chest or neck. The solution is typically prepared by a pharmacist or other healthcare professional and is customized to meet the individual nutritional needs of each patient.
TPN is a complex therapy that requires careful monitoring and management by a team of healthcare professionals, including a dietitian, pharmacist, and nurse. Potential complications of TPN include infection, liver disease, and electrolyte imbalances, among others.
