Pedemy All toolsChoose the age, enter weight and time, then mark the burned fraction of each region.
This calculator estimates the burned body surface area in children using the Lund–Browder chart and works out Parkland fluid resuscitation. It is for clinicians in emergency and acute care settings.
You choose the age band, because Lund–Browder adjusts the head, thigh and lower leg percentages with age. You then enter the weight and hours since the burn, and mark the burned fraction of each body region, from none to all. The tool adds these to give the % TBSA. Check boxes record full-thickness burns, burns to special areas (face, hands, feet, genitals, perineum or major joints) and inhalation, electrical or chemical injury or possible abuse.
At 10% TBSA or more, the result gives the Parkland 24-hour total of 4 mL × kg × %TBSA of lactated Ringer, with half over the first 8 hours from the burn and half over the next 16. Children under 30 kg also get maintenance fluid with dextrose and a urine output target of 1 mL/kg/h. It lists analgesia, first aid such as 20 minutes of cool running water, and burn center referral criteria. Sources include Lund and Browder 1944, Baxter and Shires 1968, the American Burn Association referral guidelines (2022) and the ISBI Practice Guidelines (2016).
The 24-hour total is 4 mL × weight in kg × %TBSA of lactated Ringer. Half is given over the first 8 hours from the time of the burn and half over the next 16 hours. The tool notes many centers start at 3 mL/kg/%TBSA in children and titrate to urine output.
The tool targets 1 mL/kg/h for children under 30 kg and 0.5 mL/kg/h for heavier children, with the fluid rate adjusted hourly.
Referral criteria listed are partial-thickness burns over 10% TBSA, any full-thickness burn, burns to the face, hands, feet, genitals, perineum or major joints, and inhalation, electrical or chemical injury or possible abuse.
