What Are Antimicrobial Wound Dressings?
Definition and Purpose
Antimicrobial wound dressings are specialized medical products designed to protect wounds while actively combating infection. These dressings incorporate antimicrobial agents that inhibit or kill bacteria, fungi, or viruses, reducing the risk of infection and promoting healing. They are commonly used in chronic wounds, surgical sites, burns, and ulcers that have a high risk of microbial contamination.
Common Types of Antimicrobial Agents
Antimicrobial agents used in wound care include:
- Silver: Broad-spectrum antimicrobial with proven efficacy against antibiotic-resistant bacteria.
- Honey: Offers antibacterial and anti-inflammatory properties; Manuka honey is the most common medical-grade variant.
- Iodine: Effective against a wide range of pathogens, especially in acute and infected wounds.
- PHMB (Polyhexamethylene Biguanide): Used in advanced wound dressings due to its antimicrobial and biocompatible nature.
How Do Antimicrobial Dressings Work?
Mechanism of Action
Antimicrobial dressings work by releasing active agents into the wound bed, disrupting microbial cell walls or inhibiting essential cellular functions of pathogens. This action helps lower bacterial load, reduces inflammation, and supports the body's natural healing process.
Role in Reducing Infection and Promoting Healing
By lowering bacterial counts and maintaining a moist wound environment, these dressings prevent biofilm formation, which is often a major barrier to wound healing. Their use also decreases the need for systemic antibiotics, thereby reducing antibiotic resistance risks.

How to Choose the Right Antimicrobial Dressing
Dressing Form Factors
Common types include:
- Foam Dressings: Ideal for cushioning and absorbing exudate
- Hydrocolloids: Great for shallow, low-exudate wounds
- Alginates: Highly absorbent, ideal for deep or heavily draining wounds
Factors to Consider
- Wound size and depth
- Level of exudate
- Skin sensitivity
- Infection severity
How to Use and Change Antimicrobial Dressings
Step-by-Step Guide
- Clean the wound using sterile saline solution
- Pat the surrounding area dry
- Apply the antimicrobial dressing according to product instructions
- Secure with secondary dressing if required
Frequency of Dressing Changes
Most antimicrobial dressings can be left in place for up to 3–7 days, depending on wound condition and exudate level. Always monitor for signs of infection or deterioration.
