Patients with diabetes mellitus have pain in the lower limbs, skin ulcers, gangrene of the extremities and other lesions due to various reasons such as peri-periodic neuropathy or/and vascular lesions and bacterial infections are collectively called diabetic foot, whose main clinical manifestations are foot ulcers and gangrene. Internal treatment 1, control diabetes. 2, vasodilation, anticoagulation, thrombolysis, improve circulation and microcirculation. 3.Anti-infection. 4.Treat peripheral neuropathy. 5.Control other related and chronic complications. Treatment of diabetic foot trauma Exorcism and myogenesis method: The early stage is mostly based on “exorcism”, while the later stage is based on “astringent myogenesis”. Most of the ointment and oil gauze wet dressing are used to remove decay and regenerate muscle. The “expel decay” medicine is mostly used to clear heat and detoxify the blood and remove blood stasis, and the “astringent and regenerative” medicine is mostly used for Astragalus, Wu Bei Zi, Bitter Ginseng, Bupleurum, Pearl Powder, Talc, Ice Chips, Alum, etc. The drugs used to remove the decay and regenerate the muscles are: ice chips, pearls, musk, light powder, etc. 1, blisters, blood blisters treatment: larger blisters, blood blisters will be the contents of the extraction, 2.5% iodine aseptic bandage. 2. Treatment of wet gangrenous wounds: early incision and drainage, moderate debridement, temporary preservation of poorly defined boundaries, excision of inactivated subcutaneous tissue, adipose tissue, fascial muscle, preservation of necrotic tendons, removal of dead bone, sinus incision. Remove overgrown granulation tissue, keep moist, gauze with myogenic oil, wet dressing with hypertonic saline, epithelial growth stage Myogenic cream, myogenic oil, myogenic gauze applied externally. 3, dry gangrene Gangrene limited clearly delineated, ischemic ulcers are not prematurely cleared, the scope of clearance should be small. 4, neurogenic ulcers Ulcers on the heel are more deep and difficult to treat, other parts can heal with clearing.
