What is the recommended topical treatment for burns?

Recommended Topical Treatment for Burns

For burn wound care, antiseptic dressings are recommended as first-line treatment, with silver sulfadiazine being appropriate for contaminated burns but not for long-term use on superficial burns due to its association with prolonged healing. 1

Initial Wound Management

1. Initial cleaning:

   • Clean burn wounds with tap water, isotonic saline solution, or an antiseptic solution before applying any dressing 1
   • Perform wound care in a clean environment under appropriate pain management (deep analgesia or general anesthesia may be required) 1

2. Cooling (for limited burns only):

   • Apply cooling only for:
     • Adults with <20% total burned surface area
     • Children with <10% total burned surface area
     • Only in the absence of shock 1
   • Cooling with tap water for 20-39 minutes can significantly reduce burn depth and need for skin grafting 1
   • Avoid prolonged cooling to prevent hypothermia

Dressing Selection Algorithm

1. For contaminated or large burns:

   • Antiseptic dressings are appropriate 1
   • Silver sulfadiazine is indicated for prevention and treatment of wound sepsis in second and third-degree burns 2

2. For superficial burns:

   • Avoid prolonged use of silver sulfadiazine as it is associated with delayed healing in superficial burns 1
   • Consider alternative dressings such as sterile gauze, interface dressings, or non-adhesive dressings 1

3. For infected wounds:

   • Topical antibiotics should be reserved for infected wounds only, not as first-line prophylaxis 1

Application Technique

• Apply dressings after thorough wound cleaning 1
• When applying dressings to limbs, prevent bandages from causing a tourniquet effect 1
• For circular dressings, monitor distal perfusion regularly 1
• Ideally, re-evaluate dressings daily 1

Silver Sulfadiazine Considerations

• Indications: Prevention and treatment of wound sepsis in second and third-degree burns 2
• Application frequency: Once-daily application is as effective as twice-daily application, with potential benefits of decreased length of stay, reduced pain levels, and fewer hospital-acquired complications 3
• Efficacy: Silver sulfadiazine has excellent antimicrobial spectrum, low toxicity, and ease of application with minimal pain 4

Important Cautions and Contraindications

• Avoid prolonged use: Silver sulfadiazine is associated with prolonged healing if used for a long time on superficial burns 1
• Side effects to monitor: Allergic reactions to sulfadiazine moiety, silver staining of the treated burn wound, hyperosmolality, methemoglobinemia, and hemolysis in patients with G6PD deficiency 5
• Sulfa allergies: While caution is warranted, a retrospective study found no adverse reactions when silver sulfadiazine was used in patients with documented sulfa allergies 6
• Avoid systemic antibiotic prophylaxis: Systemic antibiotic prophylaxis should not be administered routinely to burns patients 1

Advanced Options

• Combination therapy: Silver sulfadiazine plus hyaluronic acid may reduce healing time, accelerate reduction of local edema, and have favorable antibacterial, anti-edematous, and local analgesic effects compared to silver sulfadiazine alone 7

Remember that wound care is not a priority over resuscitation in severe burns, and consultation with a burns specialist is ideal for determining the most appropriate dressing for specific clinical situations 1.
