Question

For those that saw my other post-this is number 2 on the same hmwk assignment-Thanks!

2. 20% dextrose/6.0% amino acids at 50 ml/hour for 24 hours plus 20% lipid at 21 ml/hr for 12 hours.

a) Total kcal=

b) CHO grams=

c) Protein grams=

d)Fat grams=

e)NPC:N=

Calculations for Lipids:

Kcal: 1800kcal X .20 (20% fat) = 360 kcal from fat

360 kcal divided by 2 (20% IVFE) = 180 ml of 20% IVFE/day

180 ml divided by 12 hours = 15 ml of 20% fat for 12 hours

Calculations for Protein:

1800 ml (total volume) – 180 ml (lipids volume) = 1620 ml

75 gm divided by 1620 ml X 100 = 4.6, you can round up to 5% AA

75 grams X 4 kcal/g of protein = 300 kcal

Calculations for Dextrose:

1800 kcal (total) – 360 kcal (lipids kcal) – 300 kcal (protein kcal) = 1140 Kcal of Dextrose

1140 kcal divided by 3.4 (kcal/g of dextrose) = 335 gm of dextrose

335 g divided by 1620 ml X 100 = 20% Dextrose

PLEASE SHOW ALL WORK AND STEPS! Thank you so much in advance!

Energy production: For dextrose 3.4 kcal/g, for protein 4 kcal/g, and for fat it is 9kcal/g.

20% dextrose i.e. 20g/100ml,

so that 10g/50ml/hour, therefore for 24h it is 240g,

6% protein, 6g in 100 ml, so that 3g in 50 ml, Hence for 24 hours is is 72g

240g dextrose+72g protein present in 1200 ml for 24 hr.

similarly, 20% lipid i.e. 20g/100ml, so that for 21 ml it is 4.2g, hence for 12 hrs it is 50.4g

a. Total kcal= (240x3.4)+(72x4)+(50.4x9)= 1557.6 kcal, carbohydrates & proteins per 24hrs and fats/12hrs associated energy yield.

b. CHO =240g for 24 hours in 50 ml

c. protein=72g for 24 hours in 50 ml

d. fats= 50.4g for 12 hours in 21 ml

e. NPC (1269.6) : N (11.52)= 122:1, Here, 6.25g of protein produce 1g nitrogen (N).

Hence, total 72g proteins gives 11.52g of nitrogen.

NPC is nothing but non protein calories, so that it written like 1557.6-288=1269.6kcal.

288 kcal of protein enerrgy that is substracted from total energy 1557.6 kcal.
