CARVAJAL-GAVLESTON FORMULA
  • First 24 hours:
    • 5,000 mL x BBSA (m2) + 2,000 mL x TBSA (m2)*
    • Ringer's lactate (half in the first 8 hours and the rest in the following 16 hours). No colloid should be given.
  • Second 24 hours:
    • 3,750 mL x BBSA (m2) + 1,500 mL x TBSA (m2) of dextrose solutions with electrolytes (based on patient's electrolytic anomalies)

*BBSA (burned body surface area): Formula: TBSA x %/100

**TBSA (total body surface area): Formula: (W (kg) x H (cm)/3600)

Notes:

Colloids are recommended at least 12-24 hours after the burn, using albumin poor in salt 1 g/kg/day divided in 3 doses (this aims at maintaining albumin levels above 2.4 g/dL).

If the patient develops myoglobinuria or hemoglobinuria (electrical burns, for example), take the following steps: 

  • increase fluids administered to achieve a urine output of 3-5 ml/kg/hour
  • add bicarbonate to solutions
  • if urine output does not improve, add mannitol to therapy
