Fluid Resuscitation for Pediatric Burns

Rationale for Fluid Resuscitation

Fluid resuscitation is a cornerstone in the initial management of severe burns, particularly for children with burns covering ≥10% TBSA 1
Children differ from adults in having a higher body surface area/weight ratio, making adult formulas inadequate for pediatric patients 2
Burned children typically require higher total fluid intake than adults in the first 48 hours, with retrospective studies showing approximately 6 mL/kg/%TBSA over that period 2

For children with burns >10% TBSA, the modified Parkland formula using 3-4 mL/kg/%TBSA is recommended 2
The higher end of this range (4 mL/kg/%TBSA) is appropriate for this child with a deep partial thickness burn 1
This should be administered as Lactated Ringer's solution, which is the preferred balanced crystalloid solution for burn resuscitation 3

Half of the calculated 24-hour fluid requirement should be given in the first 8 hours post-burn, with the remaining half administered over the next 16 hours 1
For this 5-year-old child with 15% TBSA burn, the formula would calculate as: weight (kg) × 4 × 15% TBSA = total fluid volume for 24 hours 2
Intravenous access should be obtained as soon as possible, preferably in unburned areas 4

The initial fluid rate should be adjusted based on clinical and hemodynamic parameters 5
Urine output is the easiest and fastest parameter to monitor, with a target of 0.5-1 mL/kg/hour in children 5
Inadequate fluid resuscitation can lead to burn shock, while excessive fluid administration ("fluid creep") can cause complications including compartment syndromes 5

Option B (2 mL/kg/hour regardless of burn size) fails to account for the extent of the burn and would likely result in inadequate resuscitation 1
Option E (no fluid resuscitation for burns <20% TBSA) is incorrect as children require fluid resuscitation for burns ≥10% TBSA 2
Option A (2 mL/kg/%TBSA) would provide insufficient fluid volume for a child with a deep partial thickness burn 2
Option C (3 mL/kg/%TBSA) falls within the recommended range but may be inadequate for deeper burns 2
