Burn Fluid Equation and Distribution

Burn Equation:

4mL * kg * % body burned

• 4mL * 75kg * 50% = 15,000mL = 15L

With half the fluid given in the first 8 hours and the remainder over the next 16 hours = Total of 24hrs

• \(\frac{15}{2} = \text{7.5L}\) given within the first 8hrs
• \(\frac{15}{2} = \text{7.5L}\) given within the following 16 hrs
  • Total of 15L given in 24hrs
