Maintenance Fluid Calculation for Children

For infants 3.5 to 10 kg the daily fluid requirement is 100 mL/kg.

For children 11-20 kg the daily fluid requirement is 1000 mL + 50 mL/kg for every kg over 10.

For children > 20 kg the daily fluid requirement is 1500 mL + 20 mL/kg for every kg over 20, up to a maximum of 2400 mL daily.

Please note that this calculation does not apply to newborn infants (ie, from 0 to 28 days after full term delivery).


Fluid Rate = Daily Vol / 24
