What is A 40 year woman was brought to the casualty 8 hours after sustaining burns on the abdomen, both the limbs and back. What will be the best formula to calculate amount of fluid to be replenished? and explain in detail?
Answer- A. 2 mL/kg x %TBSAFluid resuscitation in burns:According to ATLS 10th edition, 2018, the resuscitation formula used in thermal burns is 2 mL/kg x % TBSA.First 8 hours: 1 mL/kg x % TBSA (lactated Ringer solution)Next 16 hours: 1 mL/kg x % TBSA (lactated Ringer solution)For a patient presenting 8 hours after sustaining thermal burns, the total volume using resuscitation formula should be given in the next 16 hours i.e; 2 mL/kg x % TBSA in the next 16 hours while maintaining target urine output of 0.5 mL/kg/hr for adults.In adults, urine output should be maintained between 30 and 50 cc/hr to minimize potential over-resuscitation.The total percentage of the burnt area is calculated clinically using the rule of nines.
