Seven Types of Dressings for Targeted Selection

DRESSING GUIDE · Exudate Volume as the Core Selection Criterion

Wounds vary greatly in depth and exudate level, requiring different dressings. The mainstream selection framework evaluates exudate volume, wound color, tissue type, alongside the need for pressure relief and cavity packing. Below are seven dressing options for appropriate use:

DRESSING 1 Hydrocolloid Dressing Adopts patented skin-mimicking functional film to create a sealed moist environment. Absorbs low to moderate exudate and enables autolytic debridement to boost epithelial growth. Waterproof and bacteria-resistant with stable adhesion; it avoids tearing fragile granulation tissue during dressing changes. Ideal for superficial abrasions, blisters, superficial second-degree burns and Stage 2 pressure injuries.

DRESSING 2 Polyurethane Foam Dressing Multi-layer porous cushion foam structure with high exudate absorption capacity to lock large volumes of exudate and prevent peri-wound maceration. The silicone contact layer is non-adherent to wounds and offers pressure relief and cushioning. Suitable for heavily exuding wounds, pressure injuries, leg ulcers and post-operative wounds; also used over bony prominences for pressure injury prevention.

DRESSING 3 Chitosan Dressing Leverages the natural biological properties of chitosan for auxiliary antibacterial and hemostatic effects, helping reduce hypertrophic scar formation. Breathable and comfortable. Suitable for abrasions, burn wounds, surgical incisions and superficial wounds for scar prophylaxis, especially for cesarean section and thyroid surgery sites.

DRESSING 4 Alginate Dressing Seaweed fibers form a gel upon contact with wound exudate, delivering super-absorbent capacity for heavy exudate plus hemostatic performance. The material is freely cuttable for packing tunneling and cavity wounds with minimal pain during dressing changes. Mainly used for heavily exuding pressure injuries, leg ulcers and cavity wounds.

DRESSING 5 Medical Hydrogel Dressing High-water-content gel rehydrates dry wounds, softens necrotic eschar, relieves wound pain and supports debridement. Suitable for eschar-covered wounds, superficial burns, radiation dermatitis and dry chronic wounds; the preferred option for wounds with minimal exudate.

DRESSING 6 Medical Absorbent Dressing Non-woven substrate with absorbent pad, breathable, skin-friendly and non-adherent to new tissue. Highly versatile. Commonly used for routine surgical incisions and general traumatic wounds for basic wound protection.

DRESSING 7 Medical Transparent Film Dressing Patented semi-permeable thin membrane, waterproof and breathable. Wound assessment is possible without frequent removal. Mainly for secure fixation of IV cannulas and drainage catheters, and surgical infection control.

5 Core Principles of Scientific Wound Care

WOUND CARE BASICS · Guidance for Home Care

1. Cleansing: Gently irrigate wounds with suitable cleansing solutions according to wound type to avoid secondary trauma.
2. Assessment: Regularly check wound size, exudate volume, wound color, odor and peri-wound skin condition. Change dressings based on actual wound status rather than a fixed schedule.
3. Dressing Selection: Hydrocolloid for low exudate; foam or alginate for heavy exudate; hydrogel for dry eschar wounds; chitosan works well for a wide range of wounds.
4. Peri-wound Skin Protection: Protect intact surrounding skin from maceration, friction and sustained pressure to prevent new injury.
5. Timely Professional Follow-up: Chronic, infected wounds and diabetic foot ulcers or other complex wounds must be managed under medical guidance. Self-treatment is not recommended.

5 Common Wound Care Misconceptions

MYTHS · Practices That Hinder Healing

❗ Myth 1 🕳 “Wounds must stay dry and scab to heal.” This is a widely spread traditional view. Experts explain that dry conditions dehydrate and kill wound cells, while hard scabs block epithelial cell migration. A sealed moist environment under moist wound healing facilitates cell movement, achieves better healing quality and reduces scarring.

❗ Myth 2 🕳 “Apply alcohol, mercurochrome or gentian violet directly to open wounds.” Alcohol is highly irritating and damages newly formed granulation tissue. Mercurochrome and gentian violet are no longer recommended for open wounds; they also obscure the wound and interfere with clinical evaluation.

❗ Myth 3 🕳 “Change dressings daily as soon as exudate appears.” Frequent dressing changes disrupt fragile granulation tissue and cause secondary injury. Change dressings only when saturated or following product instructions; daily changes are unnecessary.

❗ Myth 4 🕳 “Standard adhesive bandages work for all wounds.” Adhesive bandages are only suitable for clean, superficial minor abrasions with slight bleeding. They cannot manage heavy exudate from deep wounds, pressure injuries or leg ulcers and easily lead to skin maceration and worsened infection.

❗ Myth 5 🕳 “Sprinkle topical antibiotic powder on draining infected wounds.” Topical powder clots over the wound, blocks drainage channels, aggravates infection and complicates subsequent debridement. Experts warn against applying powder to open wounds. Seek prompt medical care for purulent infected wounds.

A CALL FROM HUAWEI

SCIENTIFIC WOUND CARE STARTS WITH THE RIGHT DRESSING

Even minor wounds carry potential health risks. Scientific wound care is far more than simple bandaging: it relies on selecting appropriate dressings based on wound status and following the moist healing principle.

Value every small wound, choose dressings scientifically for better healing outcomes.
