Enxerto autólogo de pele, em malha, com espessura completa, na reparação de feridas carpometacarpianas de cães: resposta à irradiação laser AsGa

The purpose of this study was to evaluate, under gross examinations, the effects of laser AsGa, in autologous full thickness mesh skin grafts, to repair wound in the carpametacarpal regions of dogs. Twenty adult mongrel dogs were used in the present research, divided into two equal groups. Skin graft was apllied, in fresh wounds of the carpametacarpal regions (group I), prepared by skin excision of 7.5cm2 in both forelimbs. The donor site was the lateral thoracic wall. At the second moment, skin graft was applied, in wounds with granulation tissue (group II). Treatment laser AsGa in the graft was done always in the left forelimbs during ten days after surgery (group I and II). The treatment with laser AsGa in the receptor site (group II) was done during six days. Grafts treated with laser AsGa, showed minor exudate and edema and rosy color when compared with untreated. The irradiated graft has improvement in the "take" in the initial phase.
