 In those with poor tissue perfusion , boluses of isotonic crystalloid solution should be given . In children with more than 10 @-@ 20 % TBSA burns , and adults with more than 15 % TBSA burns , formal fluid resuscitation and monitoring should follow . This should be begun pre @-@ hospital if possible in those with burns greater than 25 % TBSA . The Parkland formula can help determine the volume of intravenous fluids required over the first 24 hours . The formula is based on the affected individual 's TBSA and weight . Half of the fluid is administered over the first 8 hours , and the remainder over the following 16 hours . The time is calculated from when the burn occurred , and not from the time that fluid resuscitation began . Children require additional maintenance fluid that includes glucose . Additionally , those with inhalation injuries require more fluid . While inadequate fluid resuscitation may cause problems , over @-@ resuscitation can also be detrimental . The formulas are only a guide , with infusions ideally tailored to a urinary output of > 30 mL / h in adults or > 1mL / kg in children and mean arterial pressure greater than 60 mmHg .
