24 Hour Fluid Requirement
• This formula allows us to calculate the fluid
needs for children based on weight in kg
• This number is the amount of fluid in mL that
the body requires to carry out metabolic
processes, and maintain homeostasis in the
body
• 24 hour fluid requirement can be met with
oral or intravenous fluids

24 hr fluid requirement
Examples
• Pt weighs 23kg
• 10kg X 100= 1000
• 10kg X 50= 500
• 3kg X 20= 60
• Pts 24 hour fluid requirement is 1560mL
• Pt weight is 9.5kg
• 9.5kg X 100= 950
• Pt 24 hour fluid requirement is 950mL
• Pt weight is 24 pounds
• 24 pounds = 10.9kg
• 10kg X 100= 1000
• 0.9kg X 50= 45
• 24 hour fluid requirement is 1045mL
• To figure out the recommended hourly rate,
divide the 24 hour fluid requirement by 24
hours
• From previous examples:
– 1560mL/24 hours= 65mL/hr
– 950mL/24 hours= 39.58mL/hr
– 1045mL/24 hours= 43.54mL/hr
