Question

A severely burned male patient (30 yo, 5’5”, 143 lb) is admitted to the burn unit (confined to bed). What is his TDE? How many protein kcal should he receive? How many mL of 70% dextrose should this patient receive in his TPN? How many mL of a 20% lipid emulsion are required?'

Answer 1

1) TDE=66.5+13.8(weight in kg) +5( heights in CM) -6. 76×age, weight in kg=143 lb=64.86 kg, heights in CM= 5'5=165.1cm =66.5+13.8(64.86) +5(165.1) -6. 76(30) =1584.88 kcal 2) protein required= 2 g/ kg/ day=2×64.86=129.72 g/ day=129.72× 4=518.88 kcal 3) TPN=TDE-PROTEIN IN Kcal=1584.88-518.88=1066 kcal, Dextrose=TPN×0.75=1066×0.75=799.5 kcal, Dextrose in grams=799.5/3.4=235.14 g So Volume of Dextrose=235.14/ 0.7 =335.92= 336 ml 4) Lipid emulsion required= TPN× 0.25 =1066× 0.25=266.5 kcal, in ml=266.5/2 kcal =133.25 ml= 134 ml
