What are the ways to properly administer TPN?
First, TPN is administered through a needle or catheter that is placed in a large vein that goes directly to the heart called a central venous catheter. Since the central venous catheter needs to remain in place to prevent further complications, TPN must be administered in a clean and sterile environment. For instance, external tubing should be changed every day and dressings should be kept sterile with replacement every two days.
What is the recommended amount of water for TPN?
Typically, TPN requires a solution of water (30 to 40mL), energy (30 to 45kcal), amino acids, essential fatty acids (1 to 2kg), vitamins and minerals. However, TPN solutions will be customized to meet each patient’s individual needs that are based on the patient’s age and organ function status. For instance, patients with heart or kidney disorders may require a limited volume of liquid intake while those with respiratory failure require a liquid emulsion that provides most of the nonprotein calories. The basic daily requirements for total parenteral nutrition information can be found in the Merck Manual.
What is TPN in medical terms?

What is partial parenteral nutrition?

What should be measured in liver tests?
Liver tests should be done. Plasma proteins (eg, serum albumin, possibly transthyretin or retinol-binding protein), prothrombin time, plasma and urine osmolality, and calcium, magnesium, and phosphate should be measured twice/week. Changes in transthyretin and retinol-binding protein reflect overall clinical status rather than nutritional status alone. If possible, blood tests should not be done during glucose infusion.

Can TPN be monitored daily?
Patients who recently received TPN should be monitored daily until stable. They require more frequent monitoring if metabolic abnormalities are detected or if the patient has a risk of refeeding syndrome. Refeeding syndrome can occur in severely malnourished and cachectic individuals when feeding is reintroduced and can lead to severe electrolyte instabilities. Refeeding syndrome can correlate with hypophosphatemia, respiratory distress, rhabdomyolysis, and acute kidney injury. Prevention of refeeding syndrome is critical and achievable with a slower initial infusion of TPN than would be exected. [18]

Why is protein important in enteral nutrition?
Proteins are hydrolyzed to smaller fragments and larger fragments require digestion. On the other hand, di- and tri- peptides are absorbed directly. The type of protein becomes important when you have a patient with absorption or digestion issues. While this is more of an issue in enteral nutrition, it is important to recognize how the type of protein could be a barrier to successful enteral nutrition. It is also important to remember that protein is needed for wound healing.

Is PN good for a patient?
In summary, PN is a possibility …but not a really good option. Providing adequate amino acids and calories is limited and puts the patient at a greater risk for adverse events. Peripheral lines are limited by the osmolality and volume that you can safely give to the patient in a 24 hour period and you will never get them enough nutrition to matter. If the physician says they want to start the PN now and they will get a central line later, remember this:
Is PN necessary for IV?
That being said, as much as it makes us cringe, PN is sometimes necessary. Patients may not be absorbing tube feeds or have anatomical/physiological disease states such as short gut syndrome that necessitate supplemented IV nutrition. However, not tolerating tube feeds is not a reason to initiate “Operation IV Liquid Big Mac”. Patients may just need a few more days to adjust to the tube feeds and regain absorption and blood flow to their GI tract.
