Negative pressure treatment of the diabetic ulcer
Diabetic ulcer is some manifestation on the skin of systematic pathological change of diabetes, also one of the typical chronic ulcer on clinic. Its pathological change factor is various, involves the change of the skin structure, vascular pathological change around, can also involve the function of the nerve ending. Because the diabetic patient's resistance is lower than that of the ordinary person, the skin is thinner than normal people, so the diabetic patient can not often control once began because of small skin damage, even jeopardize the life. Past therapeutic cycle is very long, spend bigger too. Direct against the improvement that the treatment means of the diabetic ulcer is exactly constant at present, introduce negative pressure and attract and treat this kind of method briefly as follows. The principle is similar " Do cupping " The negative pressure of the wound surface closes the auxiliary treatment, is abbreviated as VAC. How to achieve some negative pressure of Taxi? A lot of people have experience of doing cupping. Or skin that administer, reality under close negative pressure, treat similar to this on being clinical. Use special apparatus and dressing, it can be that the position treated keep airtight, avoid the infection of the external bacterium; Can also regulate the size of negative pressure, it is the patient that will not already feel that treat the position to especially feel a pain, achieve the therapeutic goal again. In fact, in the seventies of 20 reality, many pieces of literature were explored about employing negative pressure to treat wound surface and wound that the difficulty was met in the former Soviet Union. In 1993, German scientist Fleischmann,etc. applied negative pressure to the prevention that the wound surface was infected for the first time. Found finally, all wound surface was clean and fast, edema disappeared and increased fast, it is prominent to organized hyperplasia the granulation, the wound surface infects the incidence and lower than dealing with the group conventionally notably. Climate, close negative pressure to apply to infecting the wound surface treatment, the result is especially satisfied with. Is it how to treat diabetic ulcer that negative pressure treat the obvious negative pressure of the advantage and close and treat? On the whole, its advantage embodies in the following aspects: 1. Closing the environment offers a wet and protective wound surface bed. Think, the wet environment helps the wound surface to heal at present. Negative pressure attracts offering the totally close wet environment, help to keep cell vigor, promote the release of growth factor, stimulate cell hyperplasia. Can also accelerate the migration velocity of epidermis cell, promote the wound surface to heal. 2.Negative pressure attracts the low a little sour environment which supports relative oxygen deficiency of enabling the wound surface form, can inhibit the wound surface bacterium from growing. Use the wound treatment of negative pressure, the wound surface is totally closed, has prevented the invasion of the outside fungus. Negative pressure can retain on the intersection of wound and some the intersection of necrosis and organization, bacterium, secretion,etc. sucking since wound out of also, have accelerated achieving the course clearly, has reduced bacterium's reproduction. 3.Bidirectionally regulate the collagenic content of the wound surface bed, promote the wound surface to organize rebuilding. Collagen plays an important role while the wound surface heals. If the necrosis organization of the wound surface can't be removed, the wound surface will be difficult to heal; And it is that new born collagen acts as the bearing again that the wound heals. 4.It is that a blood vessel bed around of the chronic wound surface is open that negative pressure is attracted and treated, promote the blood flow to pour into, make the growth of wound surface vigorous. A lot of patients have improved the wound surface situation under the treatment that negative pressure attract. The little wound surface can be healed by oneself; The great wound surface is treated through negative pressure, has offered abundant preparation for surgery treatment, having improved surgery and treated the success rate the bed greatly, some patients have even avoided the destiny of the amputation. The negative pressure treatment is only one of the therapeutic means. Generally, the patient's wound needs appraising through the specialist, has already confirmed the concrete healing solution. Diabetic ward mates should know, control blood glucose, notice cold-proofly and giving up smoking, protecting skin not injuring, fixed physical examination etc., it is the most important that these defend suffering from Yu WeiRan's measure, it is the most effective avoiding the means that diabetic ulcer perplexes too. Find it is routed for skin to break, should seek medical advice early, don't tow again and again, it is sorry to lead to.
