A 50 kg patient has 40 % burn of the body surface area. Calculate the ringer lactate solution to be given for first 8 hours of fluid:
High-Yield Explanation
PARKLAND FORMULA: Fluid required for 1st 24 hours: - 4ml x body weight in Kg x Percentage of BSA(body surface area) - 4x50x40= 8000ml =8L over 24 hrs. - 1/2 of fluid required is given in first 8hrs, Rest in the second half. -So 4L first 8hrs and 4L in second 16hrs 2ND day fluid requirement: - It is 40-60 % of first day - So, on 2ndday: 4L New Updated ATLS Modification fluid Resuscitation Formula (NOT updated in most textbooks) BURN RESUSCITATION FLUID RATES AND TARGET URINE OUTPUT BY BURN TYPE AND AGE CATEGORY OF BURN AGE AND WEIGHT ADJUSTED FLUID RATES URINE OUTPUT Flame or Scald Adults and older children (> 14 years old) 2 mL LR x kg x % TBSA 0.5 mL/kg/hr 30-50 mL/hr Children (<1/4 years old) 3 mL LR x kg x % TBSA 1 mL/kg/hr Infants and young children (< 30 kg) 3 mL LR x kg x % TBSA Plus a sugar containing solution at maintenance rate 1 mL/kg/hr Electrical injury All ages 4 mL LR x kg x % TBSA until urine clears 1.15 mL/kg/hr until urine clears LR, Lactated Ringer's solution; TBSA, Total body surface area
