Which interventions can promote healing in a non-granulating wound?

• A. Debridement of necrotic tissue
• B. Improving nutrition
• C. Controlling infection
• D. All of the above

Answer: (D)

Healing a non-granulating wound requires removing barriers in the wound bed, supplying what the tissue needs to repair, and reducing factors that impede healing. Debridement of necrotic tissue clears the wound bed so granulation tissue can form and epithelialization can proceed, rather than being blocked by nonviable material. Improving nutrition provides essential substrates and cofactors—protein for collagen and tissue synthesis, vitamins and minerals for immune function and wound repair—so new tissue can be laid down and strengthened. Controlling infection lowers the bioburden and inflammatory burden that can stall healing and keep the wound in a non-granulating state. When these strategies are applied together, the environment becomes more conducive to granulation and closure, which is why all three interventions promote healing in a non-granulating wound.
