Why Diabetic Foot Wounds Are Different
Diabetes causes peripheral neuropathy (loss of sensation in the feet) and peripheral arterial disease (reduced blood flow). The result: patients don't feel small injuries forming, and when they do form, healing is severely impaired. A wound that would heal in a week in a non-diabetic patient can persist for months in a poorly controlled diabetic patient. Additionally, the high-glucose tissue environment is a growth medium for bacteria — making infection faster and more aggressive. Standard dressing techniques used for surgical wounds are often inadequate for diabetic foot ulcers, which require debridement, offloading assessment, and specialist dressings.
What immidit Nurses Do for Diabetic Foot Ulcer Dressing
On each visit, the nurse performs: wound assessment (size, depth, colour, odour, exudate amount); wound bed cleaning with sterile saline; debridement of loose slough or necrotic tissue if within scope; application of prescribed dressing (silver-impregnated, hydrocolloid, foam, or antimicrobial as directed by the wound care team); secure re-dressing to prevent shear; and documentation of wound progress for handoff to the treating physician. The nurse also inspects the contralateral foot for early warning signs.
Warning Signs That Require Immediate Hospital Referral
immidit nurses are trained to escalate immediately if they observe: blackening or gangrene of the wound edges; bone or tendon visible in the wound bed; rapidly spreading redness beyond the wound (cellulitis); fever, chills, or confusion in the patient; foul-smelling green or brown discharge; or significant increase in wound depth since the last visit. These signs indicate osteomyelitis or severe soft-tissue infection requiring IV antibiotics or surgical debridement — conditions that cannot be managed at home.
