COLD INJURY: LOCAL TISSUE EFFECTS 181<br />

5. Chemical burns<br />

6. Inhalation injury<br />

7. Burn injury in patients with preexisting medical<br />

disorders that could complicate management,<br />

prolong recovery, or affect mortality (e.g.,<br />

diabetes, renal failure)<br />

8. Any patient with burns and concomitant trauma<br />

(e.g., fractures) in which the burn injury poses<br />

the greatest risk of morbidity or mortality.<br />

In such cases, if the trauma poses the greater<br />

immediate risk, the patient may be initially<br />

stabilized in a trauma center before being<br />

transferred to a burn unit. Physician judgment<br />

is necessary in such situations and should be<br />

considered in concert with the regional medical<br />

control plan and triage protocols.<br />

9. Burned children in hospitals without qualified<br />

personnel or equipment for the care of children<br />

10. Burn injury in patients who will require special<br />

social, emotional, or rehabilitative intervention<br />

Because these criteria are so comprehensive, clinicians<br />

may elect to consult with a burn center<br />

and determine a mutually agreeable plan other<br />

than transfer. For example, in the case of a partialthickness<br />

hand or face burn, if adequate wound care<br />

can be taught and oral pain control tolerated, followup<br />

at an outpatient burn clinic can avoid the costs of<br />

immediate transfer to a burn center.<br />

Pitfall<br />

Patient loses airway<br />

during transfer.<br />

Patient experiences<br />

severe pain with<br />

dressing change.<br />

The receiving hospital<br />

is unable to discern the<br />

burn wound size from<br />

the documentation.<br />

The receiving hospital is<br />

unable to discern the<br />

amount of fluid resuscitation<br />

provided from<br />

the documentation.<br />

prevention<br />

• Reassess airway frequently<br />

before transfer.<br />

• When the patient has risk<br />

factors for inhalation injury<br />

or has received significant<br />

amounts of resuscitation<br />

fluid, contact the receiving<br />

facility to discuss intubation<br />

before transfer.<br />

• Provide adequate<br />

analgesia before<br />

manipulating burns.<br />

• Use non-adherent<br />

dressings or burn sheets<br />

to protect burn from contamination<br />

before transfer.<br />

• Ensure that appropriate<br />

information is relayed<br />

by using transfer forms<br />

or checklist.<br />

• Ensure that the flow<br />

sheets documenting IV<br />

fluids and urinary output<br />

are sent with the patient.<br />

Transfer Procedures<br />

Transfer of any patient must be coordinated with the<br />

burn center staff. All pertinent information regarding<br />

test results, vital signs, fluids administered, and urinary<br />

output should be documented on the burn/trauma<br />

flow sheet that is sent with the patient, along with any<br />

other information deemed important by the referring<br />

and receiving doctors.<br />

Cold Injury: Local Tissue<br />

Effects<br />

The severity of cold injury depends on temperature,<br />

duration of exposure, environmental conditions,<br />

amount of protective clothing, and the patient’s general<br />

state of health. Lower temperatures, immobilization,<br />

prolonged exposure, moisture, the presence of<br />

peripheral vascular disease, and open wounds all<br />

increase the severity of the injury.<br />

Types of Cold Injury<br />

Two types of cold injury are seen in trauma patients:<br />

frostbite and nonfreezing injury.<br />

Frostbite<br />

Damage from frostbite can be due to freezing of tissue,<br />

ice crystal formation causing cell membrane injury,<br />

microvascular occlusion, and subsequent tissue anoxia<br />

(n FIGURE 9-8). Some of the tissue damage also can result<br />

from reperfusion injury that occurs on rewarming.<br />

Frostbite is classified into first-degree, second-degree,<br />

third-degree, and fourth-degree according to depth<br />

of involvement.<br />

1. First-degree frostbite: Hyperemia and edema are<br />

present without skin necrosis.<br />

2. Second-degree frostbite: Large, clear vesicle<br />

formation accompanies the hyperemia and<br />

edema with partial-thickness skin necrosis.<br />
