For a superficial‑to‑moderate partial‑thickness scald burn covering <10 % total body surface area in an adult, is a sterile collagen sheet the appropriate primary dressing and what are its benefits?

Collagen Sheet Dressing for Superficial-to-Moderate Partial-Thickness Scald Burns

Collagen sheets are an appropriate and effective primary dressing for superficial-to-moderate partial-thickness scald burns covering <10% TBSA in adults, offering faster healing, reduced pain, and decreased need for dressing changes compared to traditional silver sulfadiazine.

Initial Management Before Dressing Application

Before applying any dressing, immediate cooling with clean running water for 5-20 minutes is the critical first step to limit tissue damage and reduce pain 1, 2. This must be performed first, once the patient is removed from the thermal source 3.

Pre-Dressing Steps:

• Remove jewelry from the affected area before swelling occurs to prevent vascular compromise 2, 4
• Gently cleanse the wound with tap water or isotonic saline 1, 2
• Administer over-the-counter analgesics such as acetaminophen or NSAIDs for pain management 2, 4

Evidence Supporting Collagen Sheet Use

Healing Outcomes

Collagen sheets demonstrate superior healing compared to silver sulfadiazine (SSD), the traditional standard:

• Mean healing time with collagen: 10.47 ± 2.21 days versus 13.07 ± 2.33 days with 1% SSD (p<0.001), representing a statistically significant 2.6-day reduction 5
• Good quality of healing was significantly higher in the collagen group compared to SSD 5
• For superficial (2a degree) burns, perforated collagen membranes achieved healing in 9 ± 3.5 days 6

Pain Management Benefits

• Collagen sheets significantly decrease pain and reduce the need for analgesics compared to SSD 5
• The dressing eliminates painful daily dressing changes to the burned epithelial surface 7
• In pediatric studies, 79% of patients had the collagen remain intact while the wound healed underneath with minimal analgesic requirements 7

Practical Advantages

• Once applied and confirmed adherent after 24 hours, collagen sheets can be left open to air without repetitive dressing changes 7
• This markedly simplifies wound care for both patient and provider 7
• Infection rates are comparable to SSD, showing no increased infection risk 5

Application Protocol for Collagen Sheets

1. After initial cooling and cleansing, apply the collagen sheet directly to the debrided burn wound 7
2. Secure with steri-strips, kerlix, and an ace wrap 7
3. After 24 hours, confirm adherence of the collagen sheet 7
4. Once adherent, leave open to air without further dressing changes 7
5. Monitor for signs of infection (increased pain, redness, swelling, or discharge) 2

Important Technical Consideration

Perforated collagen membranes perform better than non-perforated versions, allowing exudate drainage while maintaining wound coverage 6.

Comparative Context with Other Dressings

While the 2020 International First Aid Consensus states "no treatment recommendation is made at this time" regarding optimal dressing type for thermal burns 3, this reflects the lack of first aid setting evidence rather than ongoing medical care. The guideline explicitly notes that identified studies focused on dressings as part of ongoing medical care for partial and full-thickness burns 3.

Recent research evidence consistently shows:

• Silver sulfadiazine is associated with poorer healing outcomes than biosynthetic (skin substitute) dressings, silver-containing dressings, and silicon-coated dressings 8
• Nanosilver foam dressings showed even faster re-epithelialization than collagen, though collagen still outperformed traditional SSD 9

When Collagen Sheets May Not Adhere

Collagen sheets may fail in approximately 21% of cases 7:

• Progression of burn to full thickness (most common reason for failure) 7
• Non-adherence over joints 7
• Unexplained non-adherence in rare cases 7

In these situations, alternative dressings such as petrolatum-based antibiotic ointments with non-adherent dressings should be used 1.

Critical Situations Requiring Specialized Care

Seek immediate medical attention or burn center referral for:

• Burns involving face, hands, feet, or genitalia regardless of size 2, 4
• Burns covering >10% body surface area 4
• Signs of inhalation injury (soot around nose/mouth, difficulty breathing) 2
• Signs of infection developing during treatment 2

Common Pitfalls to Avoid

• Never apply ice directly to burns as this causes further tissue damage 1, 2, 4
• Never apply butter, oil, or other home remedies 1, 2, 4
• Do not use silver sulfadiazine for prolonged periods on superficial burns as it may delay healing 4
• Do not routinely debride intact blisters; preserve the blister roof as a biological dressing 4
