In fact, Liu Aunt than the exception. Because every four people with diabetes have a doctor because of foot problems, 15% of patients had foot ulcers occur in life. More alarming is that 45% ~ 70% of amputations occurred in the misfortune of patients with diabetic foot ulcers. Once faced with amputation, not only an increase in medical expenditures, and the patient's physical, mental, family and even the economy will be affected.
Lightly: loss of a small toe
Most people foot bumps, at most 35 days to heal without problems, why the feet of diabetic patients are particularly vulnerable to injuries but no better?
Neuropathy and vascular disease is a common complication of diabetes. Reduced autonomic neuropathy makes the sweat and cause the skin dry and chapped easily, sensory nerve lesions give the feeling of pain in patients with slow change. Vascular lesions leading to the size of blood vessels are easily blocked, cyclic variation, the skin prone to "malnutrition."
Sensory change slow and easy to dry and chapped skin, bumps or a tear a little careless, it is easy to bacterial infection, coupled with poor blood circulation, tissue hypoxia, leukocytes can not completely kill the invading bacteria, antibiotics can not be through blood cycle time to kill bacteria, so bacteria can spread quickly, cause a large number of muscle tissue necrosis fester and become diabetic foot ulcers.
Aunt Liu is such a small wound all the way developed into major problems. She likes to wear sandals, one day found that his left little toe broken a small hole in, did not mind a delay of a week the wound is getting bigger, the muscles around the toes black, with blood leaking from inside. Liu aunt with her daughter rushed to large hospital for treatment, doctors removed her little toe. Liu aunt sad kept alive that she worried about is that the wound or the dark damp.
Hyperbaric oxygen joining "treatment Corps"
Liu Aunt accepted treatment is multi-faceted, and can be described as a "treatment Corps", including controlling blood pressure, blood sugar, blood lipids, hypercoagulable state as well as infections, large blood vessels, capillaries and nerve disease treatment. Later, the doctor suggested Aunt Liu comprehensive treatment of the above-mentioned basis, with hyperbaric oxygen therapy in order to promote wound healing. After a detailed explanation of some doctors, Liu Aunt understand this truth, so in the second debridement surgery (excision and cleaning the wound of necrotic tissue) before and after, received hyperbaric oxygen therapy.
After more than ten times of hyperbaric oxygen therapy (two courses), and comprehensive treatment, the wounds of Aunt Liu obvious improvement has been healing rapidly changing and new flesh, finally can be discharged to go home. She also learned to always view whether unusual or foot wounds, dry skin, rubbing lotion on the need lubrication, select the soft leather fit the Baoxie, wearing cotton, thick soft, loose socks to protect feet.
For diabetic foot wounds in patients with the problem, the traditional treatment is to give antibiotics to control infection, local debridement and dressing, if it continues to deteriorate only take the amputation of a passer-by, which patients and their families are a heavy blow. Diabetic foot lesions had the medical, economic and social ones. Hyperbaric oxygen by adding "treatment Corps", even if still amputation, but also have the opportunity to not remove too much range.
Promoting wound healing: the mechanism is simple
Hyperbaric oxygen therapy principles are not complicated, it is the use of higher than the atmospheric pressure of 2.5 ~ 3 times the high-pressure chamber, inhaled 100% oxygen, the concentration and pressure have increased in the case, not only red blood cell oxygen content increased, also allow oxygen dissolved into the plasma inside, so that oxygen diffusion into hypoxic organizations (such as diabetic wounds, osteomyelitis, severe infection of the wound, etc.), oxygen enrichment can stimulate the formation of collagen fibers, promoting angiogenesis, but also enhance the white blood cell phagocytosis, inhibit bacterial toxins, and thus control infection, promote wound healing.
In general, hyperbaric oxygen therapy in wound healing and immune regulation have a role in such areas to help improve microcirculation, thus preventing and treating diabetic complications, while hyperbaric oxygen therapy reduces the organization because of congestion caused by ischemia and hypoxia edema, high blood sugar due to the long-term damage caused by tissue hypoxia and peripheral neuropathy have therapeutic effects. In addition, hyperbaric oxygen therapy can inhibit the growth of anaerobic and aerobic bacteria breeding, to enhance leukocyte phagocytosis and bactericidal ability to enhance the sterilization of certain antimicrobial agents or antimicrobial effect, thereby to control wound infection. Should be pointed out that, although the high-pressure oxygen therapy is widely used in clinical subjects, there are certain contraindications. In view of this, whether hyperbaric oxygen therapy, treatment pressure, time, treatment is required under the guidance of a doctor.
