Management of wounds after toe amputation for diabetic foot gangrene

  Modalities of toe amputation Outpatient debridement: debridement of wet necrosis from proximal to distal, probing for deep pus cavities and healthy granulation beneath the necrosis: removed necrotic tissue is sent to the laboratory for culture and drug sensitivity testing.  Surgical debridement: remove all necrotic tissue down to the bleeding tissue and open all sinus tracts, rinse and caulk with petroleum jelly gauze or Levanox gauze and leave the wound open without sutures.  Toe or radial amputation: removal of one or more gangrenous toes and, if necessary, the metatarsal bone attached to it.  Postoperative wound management 1. At the time of postoperative external dressing, the wound may still have necrotic and decaying tissue. 2% sodium hypochlorite solution should be applied to rinse (1% sodium hypochlorite solution 20 ml added to 980 ml of distilled water to prepare). After the debridement is finished, rinse the wound edges and surrounding skin with saline to prevent skin dryness and irritation. Stop flushing with sodium hypochlorite solution when the wound no longer appears necrotic.  2.The edges of the wound should be debrided every 3 days after surgery, and all calluses, putrefied flesh and lifeless tissues should be removed to keep the wound open and drained.  3.It is not necessary to dress the wound with a large amount of gauze, and use a tube-type bandage to fix it at the appropriate position to make lifting for inspection and dressing change simple and convenient.
