	Total parenteral nutrition - Wikipedia, the free encyclopedia
		Total parenteral nutrition (TPN), is the practice of feeding a person without using the gut, i.e.
		Battery-powered ambulatory infusion pumps are used with chronic TPN patients, and usually the pump and a small (100 ml) bag of nutrient to keep the vein open are carried in a fanny pack.
		The most common complication of TPN use is bacterial infection, usually due to the increased infection risk from having an indwelling central venous catheter.

	Total Parenteral Nutrition
		The use of nutritional therapy in the cancer patient is tailored to complement the primary treatment.
		In summary, the provision of TPN during chemotherapy should be reserved for those patients with hypoalbuminemia or weight loss of greater than 10% who are responsive to prescribed dose and schedule of chemotherapy.
		TPN as an adjuvant to chemotherapy does not seem to be useful unless there are prolonged periods of gastrointestinal toxicity such as allogenic bone marrow transplantations that severely limit oral intake and absorption.

	Total Parenteral Nutrition (TPN)
		TPN is a lifesaver for people who are unable to absorb adequate nutrition through their intestines.
		TPN is administered for varying hours on a daily or sometimes several times a week basis.
		TPN is a miracle, in that it keeps people alive where they cannot eat to sustain themselves, but it also has many problems.

	THE MERCK MANUAL, Sec. 1, Ch. 1, Nutrition: General Considerations
		Enteral tube nutrition may be used in patients with a functioning GI tract to supplement oral feeding or to replace it entirely.
		TPN is used not only in the hospital for long-term administration but also at home (home TPN), enabling many persons who have lost small-bowel function to lead useful lives.
		TPN requires water (30 to 40 mL/kg/day) and energy (30 to 60 kcal/kg/day), depending on energy expenditure, and amino acids (1 to 3 g/kg/day), depending on the degree of catabolism.

	Home Hyperalimentation/Enteral Nutrition
		Total parenteral nutrition (TPN), also known as parenteral hyperalimentation, is used for individuals with medical conditions that impair gastrointestinal absorption to a degree incompatible with life.
		Total parenteral nutrition for the treatment of malnutrition associated with conditions resulting in impaired absorption is considered medically necessary if the medical appropriateness criteria are met.
		Total parenteral nutrition or enteral nutrition of 750 calories per day or less for the treatment of malnutrition is considered not medically necessary.

		In 2003, the preferred method of performing TPN is with a medical infusion pump.
		Note that preparing and administering TPN are sterile procedures that should only be performed by trained personnel under medical supervision, using proper equipment.
		FFP is useful in infants with secondary immunodeficiency associated with severe protein-losing enteropathy and in whom total parenteral nutrition is ineffectual.

		However, the negative impact of TPN on quality of life, its adverse event profile, and its cost all suggest that this intervention must be used judiciously in cancer patients.
		Parenteral nutrition may be needed to give nutritional support to patients with severe acute (temporary or reversible) or chronic intestinal failure.
		Parenteral nutrition needs to be given only by health workers trained in its use otherwise life-threatening complications (especially sepsis) may occur.

	Current uses and abuses of total parenteral nutrition.
		Total parenteral nutrition remains a vital medical intervention, and in our institution it is considered as basic as intravenous fluids, antibiotics, and blood transfusions.
		It is clear that the indications for TPN are diminishing as basic science and clinical studies continue to find increased benefits associated with enteral feeding, and as techniques for initiating enteral nutrition improve.
		Because of unproven benefits and/or increased complication rates, TPN has lost favor in the treatment of conditions that were previously thought to require parenteral alimentation, such as acute pancreatitis, pediatric and adult burns, critical care, and preoperative use in patients with mild or moderate malnutrition.

	Total Parenteral Nutrition
		TPN is not indicated in the management of cancer-related anorexia and cachexia which is the most common cause of decreased appetite and weight loss in cancer patients.
		The primary goal would be to maintain or restore the patient's nutritional status and to correct or prevent malnutrition-related symptoms.
		Examples for which TPN may be indicated: patients with ovarian carcinoma with bowel obstruction; patients with head and neck cancers when enteral nutrition is not possible.

	Deaths Associated with Thiamine-Deficient Total Parenteral Nutrition
		For the two patients on whom autopsies were performed, examination of the brain showed lesions diagnostic of acute thiamine deficiency: necrosis and petechial hemorrhages in each mammillary body, hypothalamic neovascularization, and petechial hemorrhage with gliosis and engorgement of parenchymal periaqueductal blood vessels near the third and fourth ventricles.
		Thiamine was absent from the TPN fluids given these patients during a nationwide shortage of intravenous (IV) multivitamins resulting from substantially reduced production by one of the two major domestic manufacturers of multivitamins in June 1988.
		When the hospital supply of multivitamins for outpatient TPN was exhausted on September 12, she could have had at most a 2-day supply at home.

		The Refeeding Syndrome is conformed by a series of clinical manifestations related to electrolytic alterations associated with the restarting of the nutritive contribution both enteral and parenteral.
		Nineteen patients were eliminated due to a nutrition period of less than 7 days, and other 19 were also eliminated for presenting electrolytic alterations before the nutritive support started.
		Conclusions: Refeeding Syndrome is a frequent entity in malnourished patients submitted to enteral or parenteral nutrition; at least in this study it was of 48%; its presence was followed by a longer hospital stay and a higher mortality rate.

		In severe cases, nutrition must be achieved by given an IV (intravenous) fluid containing fat, carbohydrates, vitamins, and other substances.
		Because IV tubes (catheters) placed in the arm only last a few days, patients requiring long-term TPN (total parenteral nutrition) often have a central line (or "port") installed surgically.

		True TPN could be possible, but the sad state of knowledge of allopathic medicine in the area of nutrition makes this unlikely to occur in the real world.
		Since nothing similar to real TPN is commercially available, it would have to be compounded by a compounding pharmacy (which is rare) from the prescription of a doc knowledgeable in nutrition (also rare).
