Nutrition

Resting metabolic demand ≈ 25kcal/kg/day

Indirect calorimetry: REE (kcal/day) = 3.94 x VO2 (L/day) + 1.11 x VCO2 (L/day)
 
Mifflin-St Jeor equation:
Basal Metabolic Rate (men) = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5
Basal Metabolic Rate (women) = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161

Original Harris-Benedict equation:
Basal Metabolic Rate (men) = 66.473 + 13.75 x weight(kg) + 5 x height(cm) - 6.8 x age(y)
Basal Metabolic Rate (women) = 655.09 + 9.56 x weight(kg) + 1.84 x height(cm) - 4.67 x age(y)
 
Protein ≈ 1.5-2.5 g/kg/d (critically ill)
Lose ~ 15% in dialysis

Carbohydrates = 3.4 kcal/g
Protein = 4 kcal/g
Lipids = 9 kcal/g
etOH = 7 kcal/g



 
Nitrogen Balance = Total protein intake (grams)/6.25 - (UUN + 4 grams)
Goal +2 - +4 g/day

5% dextrose = 50 grams /1 liter x 3.4 kCalories/gram = 170 kCalories per liter
Propofol = 1.1 kcal/mL


Prealbumin = transthyretin
transports thyroxine and retinol
originally called prealbumin (or thyroxine-binding prealbumin) because it ran faster than albumin on electrophoresis gels
