Experimental study of animal model with retrograde avulsion injury of skin

Objective T o evaluate the treatment of avulsion injury of palmar skin.Methods We regarded 16New Zealand white rabbits as experimental model.The prosterior limbs of the rabbits were randomly divided into experimental and control groups,group A is experimental;group B is control.3:1distal-based-avulsion skin was made in the animals of group A and B respectively.Two veins were anastomosised in expe rimental side.As control another side was just sutured back to the original sit e.The survival condition was evaluated based on observation,pathological exami nation and survival area calculating.Results The survival condited of experimen tal group skin was better than that of in control group,which based on these de tection methods,t=7.140t 0.01(11) ,P0.01.Conclusion Venous-blood-flow is very important to avulsion skin,which can augment the quality and survival area of avulsion skin.This the rapy open up a path of treatment to the avulsion injury of palmar skin in clinic al practice.
