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
