What is the formula for calculating burn fluid replacement in children?

The volume of fluid replacement in the first 24 hours after burn = burn area × child weight ×1.5+2000. The ratio of crystalloid solution to colloid solution is usually 2:1. The exudation is fastest within 8 hours after burn, and one half of the total volume of fluid replacement needs to be infused within 8 hours. The volume of fluid replacement in the second 24 hours is half of that in the first 24 hours, but the volume required by physiology remains unchanged.
