Wound Dressing Types Reference
Gauze, foam, hydrocolloid, hydrogel, alginate, transparent film, and antimicrobial dressings — indications, contraindications, change frequency, advantages, limitations, and NCLEX pearls for each type.
Educational use only. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
Selection principle: Match dressing to wound. The primary dressing contacts the wound bed; secondary dressings cover and secure the primary. Drainage amount is the most critical factor in dressing selection.
Quick Selection Guide
| Wound Situation | Best Dressing |
|---|---|
| Dry wound — needs moisture | Hydrogel |
| Light exudate — shallow wound | Hydrocolloid or transparent film |
| Moderate exudate | Foam dressing |
| Heavy exudate | Alginate or foam |
| Infected wound | Antimicrobial (silver or iodine-based) |
| Needing debridement (necrotic/sloughy) | Hydrogel (autolytic), gauze wet-to-moist (mechanical), or enzymatic |
| Packing dead space / tunnels | Alginate rope, hydrogel, or gauze strip |
| Stage 1 pressure injury / skin protection | Transparent film or foam |
| IV site | Transparent film |
| Active bleeding | Alginate (hemostatic) |
Dressing Details
Gauze
Traditional multipurpose dressing
Moisture balance: None — dries out wound
Change frequency: Every 4–24 hours (wet-to-moist: change before fully dry to avoid tissue disruption)
Examples: Kerlix, plain gauze 4×4, non-adherent gauze (Telfa, Adaptic), impregnated gauze
Indications
- Packing wound cavities and tunnels
- Wet-to-moist debridement of sloughy wounds
- Secondary dressing over primary dressings
- Wounds requiring mechanical debridement
Contraindications
- Clean granulating wounds — will disrupt granulation tissue on removal
- Wounds with viable tissue where disruption is to be avoided
- Do NOT use dry gauze on epithelializing wounds
Advantages
- Inexpensive, widely available
- Versatile — can be used wet or dry, rolled, packed
- Comes in many sizes and forms
- Useful for packing dead space
Limitations
- Painful removal when dry — adheres to wound
- Disrupts granulation tissue
- Requires frequent changes
- Poor moisture balance for healing wounds
- May shed fibers into wound
NCLEX: Wet-to-DRY = mechanical debridement (disrupts ALL tissue). Wet-to-MOIST = debrides without excess trauma. Do NOT use on clean granulating wounds.
Foam
Highly absorbent moisture-retentive dressing
Moisture balance: Absorbs moderate to heavy exudate while maintaining wound moisture
Change frequency: Every 3–7 days or when saturated (some products designed for up to 7 days)
Examples: Mepilex, Allevyn, Biatain, PolyMem, Cutimed Siltec
Indications
- Moderate to heavy exudate
- Pressure injuries (Stage 2–4)
- Skin tears
- Around drainage tubes
- Surgical wounds with moderate drainage
Contraindications
- Dry wounds requiring moisture — does not donate moisture
- Wounds with minimal drainage — may dry wound bed
- Full-thickness burns (specialized products available)
Advantages
- Highly absorbent — reduces dressing change frequency
- Maintains moist wound environment
- Comfortable and cushioning
- Available with or without adhesive border
- Some have silicone contact layer for gentle removal
Limitations
- Not appropriate for dry wounds
- More expensive than gauze
- May macerate periwound skin if drainage is absorbed beyond dressing capacity
NCLEX: Foam = moderate to heavy drainage wounds. Best for pressure injuries with exudate. Long wear time reduces dressing change frequency.
Hydrocolloid
Self-adhesive moisture-interactive dressing
Moisture balance: Creates moist wound environment; absorbs light to moderate exudate via gel formation
Change frequency: Every 3–7 days or when edge lifting or leaking begins; inspect frequently
Examples: DuoDERM, Replicare, Comfeel, Tegasorb
Indications
- Stage 2 pressure injuries
- Light to moderate exudate
- Autolytic debridement of sloughy wounds
- Protecting intact skin over bony prominences
- Superficial/partial-thickness wounds
Contraindications
- Heavily exuding wounds — will leak at edges
- Infected wounds — occlusive environment traps bacteria
- Stage 3–4 pressure injuries (wound is too deep)
- Fragile periwound skin — adhesive may cause trauma on removal
Advantages
- Self-adhesive — no secondary dressing needed
- Waterproof barrier
- Promotes autolytic debridement
- Reduces dressing change frequency
- Comfortable
Limitations
- Opaque — cannot assess wound without removing
- Produces malodorous gel (normal) — may alarm patients/nurses
- Not for infected wounds (occlusive)
- Edge lifting on high-friction areas
NCLEX: Hydrocolloid produces normal-smelling gel under the dressing — do NOT mistake this for infection. Change when gel leaks at edges.
Hydrogel
Moisture-donating dressing for dry wounds
Moisture balance: Donates moisture to the wound bed — high water content (70–90% water)
Change frequency: Every 1–3 days (gel dries out; requires secondary dressing to cover and retain moisture)
Examples: Curasol, Intrasite Gel, Dermagran, Nu-Gel, Vigilon (sheet)
Indications
- Dry wounds requiring moisture donation
- Necrotic/eschar wounds (softens for autolytic debridement)
- Superficial burns (cooling effect)
- Radiation-damaged skin
- Painful wounds — soothing properties
Contraindications
- Heavily exuding wounds — adds moisture, worsening exudate
- Stage 1 wounds (no open wound bed)
- Infected wounds (some gel formulations may harbor organisms)
Advantages
- Donates moisture to dry wound beds
- Softens necrotic tissue for autolytic debridement
- Soothing, cooling effect — good for painful wounds
- Available as sheet or amorphous gel (for tunnels, cavities)
Limitations
- Requires secondary dressing
- High moisture content may macerate periwound skin
- Short wear time compared to foam or hydrocolloid
- Not for exudating wounds
NCLEX: Hydrogel = moisture DONOR. Use for DRY wounds. Opposite of alginate (moisture absorber).
Alginate
Highly absorbent fiber dressing derived from seaweed
Moisture balance: Absorbs up to 20× its weight in exudate; forms a soft gel on contact with wound drainage
Change frequency: Every 1–3 days or when gel forms throughout and saturates to wound edges
Examples: Kaltostat, Maxorb, Aquacel (hydrofiber — similar properties), Sorbsan
Indications
- Heavily exuding wounds
- Diabetic foot ulcers with heavy drainage
- Venous ulcers with high exudate
- Deep wounds and tunnels (rope form)
- Wounds with minor bleeding (hemostatic properties)
Contraindications
- Dry wounds — requires exudate to activate; will desiccate dry wounds
- Low-exudate wounds — inappropriate absorbency
- Third-degree burns without adequate exudate (unless specifically ordered)
Advantages
- Very high absorbent capacity
- Hemostatic — contains calcium which promotes clotting
- Forms cooling gel that fills wound contours
- Rope form for tunnels and cavities
- Non-adherent when properly moistened
Limitations
- Requires secondary dressing to secure
- Not appropriate for dry wounds
- Gel may be mistaken for necrotic tissue
- More expensive than gauze
NCLEX: Alginate = heavy drainage + hemostatic. Opposite of hydrogel. Needs exudate to activate — do NOT use on dry wounds.
Transparent Film
Thin, adherent, semi-occlusive membrane
Moisture balance: Retains wound moisture; allows gas exchange but not fluid exchange; NOT absorptive
Change frequency: Every 3–7 days for wound use; 48–72 hours for IV sites (per policy)
Examples: Tegaderm, OpSite, Bioclusive, Polyskin
Indications
- Stage 1–2 pressure injuries (skin protection)
- Superficial wounds with minimal drainage
- Donor sites (thin wounds)
- IV site dressings (primary use)
- Secondary dressing over other dressings
Contraindications
- Moderate to heavy exudate — not absorptive; will leak and require frequent changes
- Infected wounds — semi-occlusive traps bacteria
- Fragile, friable periwound skin — adhesive trauma on removal
Advantages
- Transparent — wound visible without removal
- Waterproof — patient can shower
- Inexpensive
- No secondary dressing needed for superficial wounds
- Allows oxygen exchange
Limitations
- No absorbent capacity — not for any exudate
- Adhesive trauma on fragile skin
- Difficult to apply without wrinkles
NCLEX: Transparent film = see-through, waterproof, NO absorption. Use for Stage 1–2 only. Best use: IV site dressings.
Antimicrobial (Silver / Iodine)
Infection-control dressings for infected or high-risk wounds
Moisture balance: Varies by product — available in foam, alginate, and hydrofiber forms
Change frequency: Per product specifications: typically every 3–7 days depending on product and exudate
Examples: Aquacel Ag, Mepilex Ag (silver); Iodosorb, Iodoflex (iodine); Acticoat (nanocrystalline silver)
Indications
- Clinically infected wounds
- Wounds with signs of critical colonization (increased exudate, delayed healing, wound deterioration)
- High-risk wounds (immunocompromised, diabetic wounds)
- Burns at infection risk
Contraindications
- Clean, healing wounds without infection signs — unnecessary and may impair healing with prolonged use
- Silver: caution in patients with known silver sensitivity
- Iodine (Povidone): avoid in thyroid disease, renal failure, pregnancy
Advantages
- Broad-spectrum antimicrobial activity
- Reduces bacterial bioburden without systemic antibiotic risks
- Available in multiple dressing forms
- Some products maintain activity for 7 days (sustained-release silver)
Limitations
- Not a replacement for systemic antibiotics when infection requires systemic treatment
- Prolonged use on non-infected wounds may impair healing
- More expensive than standard dressings
- Iodine products: staining, potential systemic absorption concerns
NCLEX: Antimicrobial dressings treat local infection. For systemic infection (cellulitis, osteomyelitis): systemic antibiotics are required. Do not use on clean healing wounds long-term.
