[Experimental study of free flap transplantation after debridement in early stage of electric burn].

Burned rabbits' limbs, caused by electricity, were early debrided and covered by vascularized free flaps. This method could obviously shorten the healing time and improve local conditions. Blood vessels, 3 cm beyond the margin of the wound, can be used for anastomosis if they have the following characteristics, normal elasticity of vessel wall, intact endothelium with no separation from the media, and good arterial bleeding. All the free flaps we used survived excellently.
