Document Summary
Week 21: total parenteral nutrition (tpn) 1 (part 3) Mf is a 60 yo male recently diagnosed with small bowel malignancy and underwent a partial small bowel resection. He was in good health until 3 months ago when he developed severe epigastric pain. He has been unable to keep any solid food down x 2 weeks. Mf undergoes surgery for partial bowel obstruction and tpn is initiated post-op day 1. Tpn formula : aa 10% 1200 ml; d70w 650 ml; smoflipid 20% 250 ml: estimate this patient"s protein and caloric requirements. Ibw: 50 kg + 0. 9 (185 152) = 79. 7 kg (tbw < ibw, use tbw ) Protein requirements: 1. 5 g/kg/day = 96 g/day ( 100g : calculate the total calories in the tpn formula. Aa 10% 1200 ml; d70w 650 ml; smoflipid 20% 250 ml. Aa 10% 1200 ml = 120 g x 4 = 480 kcal. D70w 650 ml = 455 g x 3. 4 = 1547 kcal.
