Cellulitis Deep subcutaneous infection of the skin typically by bacteria
that results in a localized area of erythema and inflammation.
Cellulitis most often affects the lower legs in adults as fissures in the toes (due to tinea pedis) provide a portal of entry. The disease presents with the cardinal signs of inflammation: redness, warmth, swelling, and tenderness as well as with acute fevers. Such inflammation permits bacterial infection of the dermis, and edema predisposes to bacterial infection. The epidermis is usually unaffected, although rarely blisters are present. The causative agents include Group A Streptococci and Staphylococcus aureus. In immunocompetent hosts, antibiotic therapy is most always curative

fluid shifts from plasma to interstitial space
Potassium levels rise in plasma The first hour of treatment after
burning can be crucial to the outcome.

Transfer to Burn Center Significant chemical burns.
Inhalation injury.
Burn injury in patients with pre-existing illness that could complicate management, prolong recovery, or affect mortality.
Any burn patient in whom concomitant trauma poses an increased risk or morbidity or mortality may be treated initially in a trauma center until stable before transfer to a burn center.
Children with burns seen in hospitals without qualified personnel or equipment for their care should be transferred to a burn center with these capabilities.
Burn injury in patients who will require special social and emotional or long-term rehabilitative support, including cases involving suspected child abuse and neglect.

Burn Transfers ABC Transfer of any patient must be coordinated
with the burn-center physician. All pertinent information regarding tests,
temperature, pulse, fluids administered, and urinary output should be recorded on the burn/trauma flow sheet and sent with the patient. Any other information deemed important by the referring or receiving physician also is sent with the patient.
