The formula for calculating daily fluid requirements is 0 to 10 kg: 100 mL/kg/day; 10 to 20 kg: 1000 mL for the first 10 kg of body weight plus 50 mL/kg/day for each kilogram between 10 and 20.To determine an hourly rate,divide the total milliliters per day by 24.Calculations: Child weighs 19.5 kg.Therefore the child requires 1000 mL; plus 50 mL ´ 9.5 kg = 475 mL.Next add calculated amounts: 1000 + 475 = 1475 mL,and divide by 24 hours to equal 61.45 mL per hour.This rounds down to 61 mL/hr.
