ECMO-/ECLS

a. Calculate daily protein calories
Protein Calories = 2-4 g protein/kg x 4kcal/g protein

b. Calculate daily fat calories

Fat Calories = 0.3 to 0.4 x total calories

20% IL caloric density is 2.2 kcal/ml

Fat calories/2 = ml of 20% IL

c. Calculate Carbohydrate calories

CHO calories = Total Caloric Needs- [Fat Calories + Protein

Calories]

Caloric Density of IV dextrose is 3.4 kcal/gram

CHO calories x 1 gram/3.4 kcal = grams Dextrose needed

Usually start at D10 (infants) or D12.5 for older children

Glucose infusion rate (GIR) per minute is calculated by
either of the following formulas
% glucose x ml/kg/day or %glucose x ml/hr
144 6 x body weight (kg)
