Experimental Study Of Venos-Lood Tonurture The Avulsion Injury Of Palmar Skin

Object The influence of venous-blood to to nurture the avulsion skin and the skin survival mechanism are studied hi these experiments using New Zealand white rabbits and the specimen hands as model. To evaluate the treatment of avulsion injury of palmar skin .Method : Experiment 1 :There are 16 New Zealand white rabbits in experiment 1 .The prosterior limbs of the rabbits are divided into experimental and control groups at random, group A is experimental;group B is control 3:1 distal-based-avulsion skin is made in the animals of group A and B respectively. Two veins are anastomosised in experimental side. As control another side is just sutured back to the original site. The survival condition is evaluated based on observation pathological examination and survival area calculating. Experiment 2: In order to provide scientific basis for clinical practice, we observe the hands of the specimen to know the run of palmaris superficial vein in the hands. Experiment 3: 24 cases of avulsion injury of palmar skin were primarily by anastomosing the arcus venous palmarris superficialis. 21 cases as control is just sutured back to the original site.Result rExperiment l:The survival condition of experimental group skin is better than that of control group skin based on these detection methods. t=7.140>to.o1(11), p<0.01.Experiment 2: there are many superficial venous need to be anastomot in the palmar skin. Experiment 3:The avulsion skins of 24 patients are alive. The excellent and good rate of hand function is 87.5%.Conclusion: Venous-blood-flow is very important to avulsion palmar-skin survival,which can augment the quality and area of skin .This therapy open up a path of treatment to the avulsion injury of palmar skin in clinical practice.
