Educational Pearls:

  • Initial assessment of patients with severe burn injuries begins with ABCs 

    • Airway: consider inhalation injury

    • Breathing: circumferential burns of the trunk region can reduce respiratory muscle movement

    • Circulation: circumferential burns compromise circulation

    • Exposure: Important to assess the affected surface area

  • Escharotomy: emergency procedure to release the tourniquet-ing effects of the eschar 

    • Differs from a fasciotomy in that it does not breach the deep fascial layer

  • PEEP = positive end-expiratory pressure

    • The positive pressure remaining in the airway after exhalation

    • Keeps airway pressure higher than atmospheric pressure

  • Common formulas for initial fluid rate in burn shock resuscitation

    • Parkland formula: 4 mL/kg body weight/% TBSA burns (lactated Ringer's solution)

    • Modified Brooke formula: 2 mL/kg/% (also lactated Ringer's solution)

      • Less fluid = lower risk of intra-abdominal compartment syndrome

  • Lactated Ringer’s solution is preferred over normal saline in burn injuries

    • Normal saline is avoided in large quantities due to the possibility of it leading to hyperchloremic acidosis
