To determine kcalories supplied by lipid*, multiply the volume of 10% lipid (in ml) by 1.1; multiply the volume of 20% lipid (in ml) by 2.0.
If lipids are not given daily, divide total kcalories supplied by fat in one week by 7 to get an estimate of the average fat kcalories per day.
Parenteral Nutrition (Definition)
I did have TPN for 2 weeks after my second surgery. I did lose a lot of weight – can’t remember how much but it was significant. TPN was really difficult for me mentally and physically and I hated it. But I got used to it. The last day of TPN, I actually enjoyed drinking the CAT scan milkshake you have to drink prior to the scan.
Total Parenteral Nutrition (TPN) is indicated for patient who cannot used their GI tract to absorb nutrients (eg.after GI surgery and cancer); Infections and complications are common after long term use.Short term use may be of value if it is after doctor’s careful evaluation.
