A patient, who was doing moxibustion fumigation for leg and foot pain, accidentally burned the back side of her calf and the wound has been there for more than 10 days, but it still does not scab over. What treatment is needed to make the wound scab? For this patient, I will mainly talk about the following issues, if you have a similar situation, you can pay attention to: a. Is there any effect of doing moxibustion for leg and foot pain? There is no denying that moxibustion is effective in relieving pain, and many patients do have a role to play. However, each person’s situation is different, some pain is due to arthritis, rheumatism, osteoporosis, while diabetic patients are likely to be pain caused by peripheral vascular disease and neuropathy of the lower limbs. In this case, doing moxibustion, fire therapy, heat therapy, etc. will not be effective. Instead, it will be the same as this patient, accidental burns. Second, the diabetic wound itself is difficult to heal. Because of the high blood sugar concentration in the local cells of the wound, after a series of complex changes lose a lot of nutrients, cellular immunity and resistance is weakened, affecting the wound healing. Local changes in pH have also been shown to cause infection, wound infection will naturally also hinder healing. Third, diabetic wounds can not crust. Diabetic wound infection characteristics are more complex, both anaerobic bacteria and aerobic bacteria. If the wound is scabbed, it will form a small closed environment under the scab, lack of oxygen under the scab, conducive to the reproduction of anaerobic bacteria. But our naked eye is invisible, so that a very serious infection occurs, the bone under the scab is also necrosis are possible. Fourth, the diabetic wound does not heal to do. Control of blood sugar, blood pressure, blood lipids and nutrient supply is necessary, for the treatment of the wound itself, the need to clean out the infection necrosis of inflammatory tissue, the idea of treatment should certainly avoid the misconception of making the wound quickly scab. For the treatment of diabetic patients with infected wounds that do not heal, any effective method will generally include debridement, infection control, improved circulation, nutritional trauma and debridement and muscle growth, etc. On this basis, comprehensive treatment of patients, especially the use of effective Chinese ointment topical wound, can effectively control the disease and promote rapid wound healing. If people blindly treat and ignore the characteristics of diabetic patients, it will only add to the wound.
