care is optimal for the patient. The American Burn Association recommends medical care at a burn center if the patient has any of the following":


Second- and third-degree burns that are greater than or equal to

10% of TBSA in patients younger than I 0 years of age or older

than 50 years of age


Burns of any type that are greater than 20% of TBSA in patients

between 10 and 50 years of age

• Full-thickness burns that are greater than or equal to 5% of

TBSA


Second- and third-degree burns of the face, hands, feet, genitalia, perineum, or major joints


High-voltage electrical or lightning injury


Inhalation injury or other trauma


A significant chemical burn


Pre-exisring disease in which rhe burn could increase morraliry

Resuscitative Phase

The objectives of emergency room management of the patient who has

a major burn injury include simultaneous general systemic stabilization and burn care. The prioritization of care and precautions during this initial time period have a great impact on survival and illustrate

some key concepts of burn care. General systemic stabilizacion involves

( 1) the assessment of inhalation injury and carbon monoxide (CO)

poisoning and the maintenance of the airway and vemilation with supplemental oxygen (see Appendix III-A) or mechanical ventilation (see Appendix lII-B), (2) Auid resuscitation, (3) the use of analgesia (see

Appendix VI), and (4) the treatment of secondary injuries.16

Inhalation In;ury and Carbon Monoxide Poisoning

The inhalation of smoke, gases, or poisons, which may be related to

burn injuries, can cause asphyxia, direct cellular injury, or both. Inhalation injury significantly increases mortality and varies depending on the inhalant and exposure time. There is no strict definition of inhalation injury. Inhalation injury is suspected if the patient was exposed to noxious inhalants, especially in an enclosed space, or if the patient
