Cultured epithelial autografts (CEA) have been used as an adjunct in the surgical management of extensive thermal burns. Unfortunately, the lack of a dermal matrix makes CEA susceptible to infection, shearing forces and limits their incorporation into the burn wound. A cultured composite autograft (CCA) has been developed in which autologous keratinocytes and fibroblasts are surgically harvested from the burn patient's normal skin. ⋯ Sixty percent of the burn was covered with CCA resulting in a success rate of 40%. No evidence of infection was noted, even in areas where CCA failed, although in those areas random epithelialization appeared to occur which then seemed to facilitate autograft placement. Early debridement and allografting followed by conventional autografts and CCA placement may provide an effective skin coverage strategy in patients with extensive deep burns.

Comparative Study Clinical Trial
Staged high-dose epinephrine clysis is safe and effective in extensive tangential burn excisions in children.
Prodigious blood loss commonly accompanies extensive tangential burn excisions. Staged high-dose epinephrine clysis may facilitate blood conserving excisional burn surgery. Prospective data was collected in 25 consecutive children who underwent tangential excision over the torso of at least 10% of the body surface with staged high dose epinephrine clysis. ⋯ There were no complications related to epinephrine use, graft take averaged 98 +/- 0.6% and all children survived and have been discharged home in good condition. Due to its rapid metabolism, subcutaneous epinephrine at high doses can be repetitively administered as long as time is allowed for its metabolism to occur. Use of this technique facilitates a marked reduction in blood requirements for these traditionally bloody operations.

Case Reports Comparative Study
The prognostic factors regarding long-term functional outcome of full-thickness hand burns.
The treatment of the burned hand has always been a subject of special interest. In order to obtain a better understanding of the parameters involved in the long-term functional outcome of hand burns a retrospective study was performed on 88 consecutive patients with hand burns (143 hands), treated according to a standardised protocol. Patients were followed for at least 12 months postburn. ⋯ This finding is inconsistent with the current consensus that functional outcome is improved by early excision and grafting. In practice, it suggests that hand function is well preserved when burns of uncertain depth are treated expectantly, followed by selective debridement and grafting. Advantages include reduced blood loss, no loss of vital tissue and a reduction of the need for donor sites.

Comparative Study
Progression of burn wound depth by systemical application of a vasoconstrictor: an experimental study with a new rabbit model.
The final depth of a necrosis resulting from burn trauma is determined within 3 days. The zone of stasis has the potential for complete regeneration or there may be ischemic influences that lead to necrosis. In our model, we examined the dermal influence of vasoconstrictors with reference to the development of burn necrosis. ⋯ The statistical analysis revealed significant differences with a p-value of 0.0312 (significant, when value is less than 0.05). The test results indicate that temporary reduction of skin perfusion through external administration of vasocontrictors may lead to progression of burn necrosis in our animal model. Clinically, this result indicates that for patients with burn injuries and systemic inflammatory response syndrome who have insufficient volume therapy, the administration of vasocontrictors may produce similar results in the injured area.
