How does the Parkland Burn Formula work?

Total 24h = 4 mL × Weight(kg) × %TBSA burned Then: First 8h from burn: 50% of total Then: Next 16h: 50% of total Then: TBSA = Total Body Surface Area burned.

Can you give an example of how to use the Parkland Burn Formula?

Patient Weight (kg)

TBSA Burned (%)

Formula: 4 mL × weight (kg) × %TBSA burned = 24h total (Lactated Ringer's)

The Parkland formula guides IV fluid resuscitation for burn patients in the first 24 hours using Lactated Ringer's. Half is given in the first 8 hours post-burn (not transfer).
