Table 1 Common formulas used to calculate caloric needs of burn patients

From: Nutrition and metabolism in burn patients

Adult formulas Kcal/day Comments
Harris Benedict Men:
66.5 + 13.8(weight in kg) + 5(height in cm) − 6.76(age in years)
Women:
655 + 9.6(weight in kg) + 1.85(height in cm) − 4.68(age in years)
Estimates basal energy expenditure; can be adjusted by both activity and stress factor, multiply by 1.5 for common burn stress adjustment
Toronto Formula −4343 + 10.5(TBSA) + 0.23(calorie intake in last 24 h) + 0.84(Harris Benedict estimation without adjustment) + 114(temperature) − 4.5(number of postburn days) Useful in acute stage of burn care; must be adjusted with changes in monitoring parameters
Davies and Lilijedahl 20(weight in kg) + 70(TBSA) Overestimates caloric needs for large injuries
Ireton-Jones Ventilated patient:
1784 − 11 (age in years) + 5 (weight in kg) + (244 if male) + (239 if trauma) + (804 if burn)
Non-ventilated patient:
629 − 11 (age in years) + 25 (weight in kg) − (609 if obese)
Complex formula which integrates variables for ventilation and injury status
Curreri Age 16–59: 25(weight in kg) + 40(TBSA)
Age >60: 20(weight in kg) + 65(TBSA)
Often overestimates caloric needs
Pediatric formulas   
Galveston 0–1 year:
2100(body surface area) + 1000(body surface area × TBSA)
1–11 year:
1800(body surface area) + 1300(body surface area × TBSA)
12–18 years:
1500(body surface area) + 1500(body surface area × TBSA)
Focuses on maintaining body weight
Curreri junior <1 year: recommended dietary allowance + 15(TBSA)
1–3 years: recommended dietary allowance + 25(TBSA)
4–15 years: recommended dietary allowance + 40(TBSA)
Commonly overestimates caloric needs
