A 10-month-old baby weighs 8 kilograms. What is the recommended fluid maintenance rate for this baby?

Calculation: Determine the recommended daily fluid maintenance for a baby weighing up to 10 kg. For the first 10 kg of body weight, the recommended fluid maintenance is 100 mL/kg/day. Calculate the total daily fluid maintenance for the baby. Total daily fluid maintenance (mL/day) = Weight (kg) × 100 mL/kg/day = 8 kg × 100 mL/kg/day = 800 mL/day. Convert the total daily fluid maintenance to an hourly rate. Fluid maintenance rate (mL/hr) = Total daily fluid maintenance (mL/day) / 24 hr/day = 800 mL / 24 hr = 33.333... mL/hr. = 33.3 mL/hr.
