Calculations for intravenous fluid therapy.

Maintenance Fluids	0.9% NaCl + 5%Dextrose	For the first 10 kg…4 ml/kg/h (100 ml/kg/24 h) For 10–20 kg…2 ml/kg/h (50 ml/kg/24 h) For greater than 20 kg…1 ml/kg/h (25 ml/kg/24 h)
Parkland Formula*	Ringers Lactate or 0.9% NaCl	4 ml × %TBSA × weight (kg) Half the volume is given in the first 8 h, the remainder over the next 16 h^
Modified Brooke Formula*	Ringers Lactate or 0.9% NaCl	3 ml × %TBSA × weight (kg) Half the volume is given in the first 8 h, the remainder over the next 16 h^

TBSA, Total Body Surface Area.

^*Either Parkland or modified Brooke formula should be used, and this is in addition to maintenance fluids.

^{^}Note that this is calculated from the time of injury.
