Dressing Selection for Superficially Infected Wounds
For superficially infected wounds, select dressings based primarily on exudate control, comfort, and cost—not on antimicrobial properties—as antimicrobial-impregnated dressings do not improve healing or prevent infection progression. 1
Primary Recommendation
The most recent high-quality evidence from the 2020 IWGDF guidelines provides a strong recommendation against using antimicrobial-impregnated dressings (containing silver, iodine, honey, or antibiotics) solely to accelerate healing, even in infected wounds 1. This recommendation is based on:
- A large multicenter RCT with low risk of bias showing no difference between non-adherent dressings, iodine-impregnated dressings, and carboxy-methylcellulose hydrofiber dressings in terms of wound healing or incidence of new infection 1
- Multiple Cochrane reviews confirming insufficient evidence for antimicrobial dressings in infected or contaminated wounds 2
Practical Approach to Dressing Selection
Step 1: Address the Infection Systemically
For superficial wound infections, the infection itself requires:
- Systemic antibiotics targeting the causative organism (typically S. aureus and/or streptococci for most superficial infections) 3
- Sharp debridement to remove necrotic tissue, slough, and debris 1
Step 2: Choose Dressing Based on Wound Characteristics
Match the dressing to exudate level and wound depth 4, 5:
- High exudate: Foam dressings, alginates, or hydrofiber dressings
- Moderate exudate: Hydrocolloids or foam dressings
- Low exudate/dry wounds: Hydrogels or films to maintain moisture
- Shallow wounds: Films, hydrocolloids, or thin foams
- Deeper wounds: Thicker foams, alginates, or hydrofibers
Step 3: Prioritize Practical Factors
Select based on 1:
- Cost-effectiveness (use the least expensive option that meets wound needs)
- Patient comfort and ease of application
- Frequency of dressing changes required
- Moisture balance (maintain moist wound environment without maceration)
Key Clinical Pitfalls to Avoid
Do not rely on antimicrobial dressings to treat infection: The evidence clearly shows they neither accelerate healing nor prevent infection progression 1, 2. Treat infection with appropriate systemic antibiotics and debridement instead.
Avoid honey-based dressings: Despite historical use, controlled trials show no convincing benefit, and Cochrane reviews recommend avoiding routine use until better evidence exists 2.
Don't use antibiotic-impregnated dressings: Studies show no impact on wound healing outcomes 1.
Reassess dressing choice as wound heals: As exudate levels and wound depth change during healing, the optimal dressing type may need adjustment 4, 5.
Evidence Quality Considerations
The 2020 IWGDF guidelines 1 represent the most recent and authoritative evidence, providing strong recommendations despite low-quality underlying studies. This reflects the consistent finding across multiple high-quality RCTs and systematic reviews that antimicrobial dressings offer no advantage. The strength of the recommendation comes from the absence of benefit rather than presence of harm, combined with cost considerations and the risk of promoting antimicrobial resistance.
Bottom line: For superficially infected wounds, use basic moisture-retentive dressings selected for exudate control and cost, while treating the infection with systemic antibiotics and debridement—not with antimicrobial dressings.
