Debridement and Infection Management
1. Debridement
Debridement is the removal of nonviable tissue, foreign material, and biofilm from a wound to create an optimal healing environment.
Goals of Debridement
Reduce bacterial load and biofilm
Stimulate wound healing
Improve effectiveness of topical therapies
Allow accurate wound assessment
Types of Debridement
1. Sharp/Surgical Debridement
Performed with scalpel, scissors, or curette
Fastest and most effective method
Indicated for infected, necrotic, or rapidly deteriorating wounds
Requires trained clinician and appropriate pain control
2. Mechanical Debridement
Wet-to-dry dressings, wound irrigation
Non-selective (removes healthy tissue as well)
Less commonly recommended today
3. Autolytic Debridement
Uses moisture-retentive dressings (hydrocolloids, hydrogels)
Selective and painless
Best for stable, non-infected wounds
4. Enzymatic Debridement
Topical enzymes (e.g., collagenase)
Selective and useful when sharp debridement is not appropriate
5. Biological Debridement
Medical-grade maggots
Highly selective and effective for resistant necrotic tissue
2. Infection Management
Wound infection occurs when bacterial burden overwhelms the host’s defenses, delaying healing.
Signs of Wound Infection
Local Signs
Increased pain
Erythema, warmth, edema
Purulent drainage
Malodor
Friable granulation tissue
Systemic Signs
Fever or chills
Elevated WBC
Hyperglycemia (especially in diabetic patients)
Delayed healing
