A young man weighing 65 kg was admitted to the hospital with severe burns in a severe catabolic state. An individual in this state requires 40 kcal per kg body weight per day, 1 gm of protein/kg body weight/day. This young man was given a solution containing 20% glucose and 4.25% protein. If 3000 ml of solution in infused per day:

Calories are calculated by catabolism of glucose (not proteins). Glucose: Amount of glucose in 20% glucose in 3000 ml of solution: 3000 x 20/100 = 600 gms 1 gm glucose on catabolism produces: 4.2 kcal 600 gms of glucose would produce: 600 x 4.2 = 2520 kcal Protein: Percentage of protein in fluid: 4.25% Percentage of protein in 3000 ml of fluid: 3000 x 4.25/100 = 127.5 gms Calories required for the patient: 40x65 = 2600 kcal Proteins required for the patient: 2 x65 = 130 gms
