A 45-year-old man has suffered from third-degree burns on 45% of his body. He was admitted to the Intensive Care Unit, awaiting a skin graft operation. What consideration should be taken for this patient to calculate calorie needs?
Burn surface level
A patient with 50% total body surface area burn weighs 50 kg. According to standard guidelines, how much protein should this patient receive daily? neww
50*2=100g
How many grams of protein are provided by 2 eggs, 60g of meat, and 80g of chicken?
❛ 40-52 grams
- Eggs: Approximately 6 grams of protein per egg.
- Meat: Approximately 25 grams of protein per 100 grams.
- Chicken: Approximately 31 grams of protein per 100 grams.
The energy value of one medium (50 g) egg calculated in terms of weight is derived from protein (13%), fat (12%), and carbohydrate (1%) as follows? And 75% is water
Protein: 0.13 x 50 g = 6.5g x 4 kcal/g = 26 kcal Fat: 0.12x 50 g = 6 g x 9 kcal/g = 54 kcal Carbohydrate: 0.01 x 50 g = 0.5 g x 4 kcal/g = 2 kcal
Total = 82 kcal

c) The weight when the patient has taken diuretics for several days
d) The weight of the patient minus the estimated amount of fluid retention
d) The weight of the patient minus the estimated amount of fluid retention
