Question 7#

Calorific requirements for burn-injured adult patients are:

A. Calculated based on the Cuschieri formula
B. Ideally adjusted for a calorie-nitrogen ratio of 500:1
C. 25kcal/kg + 40kcal/% burn
D. 20kcal/kg in children
E. Must be given parenterally whenever possible

Correct Answer is C

Comment:

25kcal/kg + 40kcal/% burn. The calculation is undertaken as follows: 25kcal x usual body weight in kilograms + 40 x % total body surface area burned. This is the Curreri formula (adult). For children, the formula is 60kcal/kg + 35kcal/% burn. Feeding should be given enterally when possible and the decision between naso-enteral feeding or a formal jejunostomy will depend on patient factors and ideally commence within 24 hours of admission for major burns. Many other formulae also exist, and there is no consensus as to the best regime.
