Adult Rule of Nines: head 9%, each arm 9%, anterior torso 18%, posterior torso 18%, each leg 18%, perineum 1%. Parkland = 4 × weight × %TBSA.

常见问题

What does the rule of nines cover?

Only second-degree and deeper burns. Superficial first-degree burns are excluded. For children use Lund-Browder, which adjusts head and leg percentages.

Why is Parkland fluid here?

Because Parkland volume depends directly on %TBSA — this calculator gives both in one step.
