The Toronto Equation is a formula used in burn care, particularly in the acute stage, to estimate caloric needs for patients.
Here's the equation:
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)
Where:
- TBSA = Total Body Surface Area burned (%)
- Calorie intake in last 24 h = Patient's actual calorie intake in the previous 24 hours
- Harris Benedict estimation without adjustment = Basal metabolic rate (BMR) calculated using the Harris-Benedict equation (without activity or injury factors)
- Temperature = Patient's body temperature (likely in Celsius, although the source doesn't explicitly state this).
- Number of postburn days = The number of days since the burn injury occurred.
Important Considerations:
- This formula is most useful in the acute phase of burn care.
- It's crucial to continuously monitor patients and adjust the caloric intake based on their individual needs and physiological responses. Changes in monitoring parameters should prompt formula adjustments.
