Q

Burn calculation equation? What is it used for? How is burn percentage estimated?

A

Parkland formula AKA Baxter formula
- Used to estimate the amount of replacement fluid required for the first 24hours in a burn patient

  • V (mL) = 4 x body weight x burn percentage (body SA affected by burns)
  • Burn percentage is estimated by Wallace rule of 9s in adults: 9% for each arm, 18% for each leg, 18% for front torso, 18% for back torso, 9% for head, 1% for perineum
  • Burn percentage in children: 9% for each arm, 14% for each leg, 18% front torso, 18% back torso, 18% for head
  • First half is given after 8 hours, and the remaining is given over the next 16 hours
