Abstract

The treatment application of cultured epithelial autograft (CEA) is the only selected treatment method when performing skin graft for treating massive burns over 70 to 80%. Clinically 2 types of CEA, sheet type and suspension type, are currently available in Korea. The sheet type of CEA, Holoderm(R), was commonly used since no other CEA were available. Since the recent introduction of the suspension type, Keraheal(R), the suspension type is also clinically used. Although 2 types are different in type of forms provided but both types are clinically effective for increasing survival rate of massive burn patients. The early treatment method of massive burn is selected based on the rage of burns using Warden or Parkland Formula. The escharectomy is performed within 3 to 7 days of burn then cadaver skin allograft is applied immediately. At this time, the full thickness skin biopsy in the size of 2x3 cm is obtained from non burned area such as axilla, inguinal or abdomen. Then the skin biopsy is sent to the labs. The length of culturing time is less than 3 weeks for Holoderm(R) and around 2 weeks for Keraheal(R). Holoderm(R) is provided as a sheet type. It is simply applied over 1:3~1:6 meshed skin autograft and fixed with staplers together with skin autograft. In the other hand, the suspension type of CEA, Keraheal(R), is provided in a glass vial and sprayed over 1:3~1:6 meshed skin autograft using Tissomat(R). The fibrin sealant is sprayed after application of Keraheal(R) as a fixation of suspension CEA sprayed. Extra wound care is necessary even after both types of CEA are successfully taken since CEA applied regions are much more fragile than those regions applied skin autograft only. The treatment methods of applying cadaver skin allograft and culture epithelial autograft (CEA) are the most advanced treatments available for increasing survival rate of massive burn patients. The sheet type and suspension type of CEA show difference in type of forms provided but they both show successful take rate that enhance the burn treatment. We suspect that both types of CEA still need ongoing efforts and researches to enhance their advantages and eliminate disadvantages to increase the efficacy that can promote wound healing process of massive burn patients.
