A young man weighing 65 Kg was admitted to the hospital with severe burns in a severe catabolic state. An individual in this slate requires 40 KCal per Kg body weight per day 1 gm of protein/Kg body weight/da. This young man was given a solution containing 20% glucose and 4.25% protei. If 3000 ml of solution in infused per day.
Correct Answer: Both Protein and calories would be inadequate
Description: Calories are calculated by catabolism of glucose (not proteins) Glucose: Amount of glucose in 20% glucose in 3000 ml of solution: 3000*20/100 = 600 gms. 1 gm glucose on catabolism produces: 4.2 KCal. 600 gms of glucose would produce: 600*4.2 = 2520 KCal. Protein: Percentage of protein in fluid: 4.25% Percentage of protein in 3000ml of fluid: 3000*4.25/100= 127.5 gms. Calories required for the patient: 40*65 = 2600 KCal Proteins required for the patient: 2*65 = 130 gms. Required amount Supplied by solution Calories 2600 KCal 2520KCal Proteins 130 gms 127.5 gm Ref: Sabiston 20th edition Pgno: 119
