Total Fluid Volume Qty=tbsa×Weight×1.5+2000
Lactated Ringer's Solution Volume=tbsa×Weight×1
Colloid Solution Volume= tbsa×Weight×0.5
Daily Normal Water Requirement (5% Dextrose Injection)=2000
Initial Fluid Volume=Qty/2-Current Fluid Volume
Initial Fluid Rate=Initial Fluid Volume/(8-Time After Burn)
Additional Fluid Volume=Qty/2
Additional Fluid Rate=Qty/2/16
Electrolyte Solution Volume=tbsa×Weight/2
Colloid Solution Volume= tbsa×Weight×0.25
Daily Normal Water Requirement (5% Dextrose Injection)=2000
Burn Surface Area Percentage (TBSA, total burn surface area).
During the first 24 hours after injury, adults receive 1ml of lactated Ringer's solution and 0.5ml of colloid for every 1% of second-degree and third-degree burn area, while also receiving a baseline fluid of 2000ml. Half of the estimated volume is given in the first 8 hours post-injury, and the other half in the following 16 hours; in the second 24 hours, the volume of electrolytes and colloids is halved while the baseline fluid remains unchanged.
This formula was developed in 1962 based on the early fluid resuscitation data of 147 adults with large area burns.
