Calculate burn fluid resuscitation volumes using the Parkland formula.
Half the calculated volume is given in the first eight hours from the time of injury rather than from presentation, so delayed presentation compresses the remaining time. Superficial erythema is excluded from the TBSA estimate. The formula is a starting point that must be titrated against urine output, because both under and over resuscitation cause serious harm.
Parkland Formula
Total 24 hour volume = 4 mL × weight in kg × per cent TBSA, half in the first 8 hours
This reproduces a published formula for educational and reference use only. It is not a diagnostic tool, does not account for individual clinical context, and must not be used to make or change treatment decisions. Clinical assessment by a qualified healthcare professional is always required. Significant burns are a medical emergency requiring immediate specialist care. Call emergency services. Fluid resuscitation must be titrated against clinical response by trained clinicians, and this formula only provides an initial estimate.
