What is TPN protocol?

TPN is the medical abbreviation for Total Parenteral Nutrition and it provides patients with all or most calories and nutrients through solutions that contain a mixture of protein, carbohydrates, glucose, fat vitamins and minerals using vascular access devices like PICC lines.

What labs do you monitor for TPN?

Weight, complete blood count, electrolytes, and blood urea nitrogen should be monitored often (eg, daily for inpatients). Plasma glucose should be monitored every 6 hours until patients and glucose levels become stable. Fluid intake and output should be monitored continuously.

How do you calculate TPN?

To calculate the grams of protein supplied by a TPN solution, multiply the total volume of amino acid solution (in ml*) supplied in a day by the amino acid concentration. Note: If the total volume of AA is not stated in the prescription, you can calculate it. Just multiply the rate of infusion of AA by 24 hr.

How do you administer TPN?

TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath. Patients may be on TPN for many weeks or months until their issues resolve.
