Topical Antimicrobials Used in Burn Care

Agent Advantages Disadvantages Nursing Implications
Silver sulfadiazine 1% (Silvadene)

Broad-spectrum antimicrobial
Antifungal
Nonstaining
Relatively painless
No systemic metabolic abnormalities

Less eschar penetration than mafenide acetate (Sulfamylon)
Decreased granulocyte formation; transient leukopenia
Macular rash
Check for allergy to sulfa

Mafenide acetate
(Sulfamylon)
cream or solution

Eschar penetration
Effective with Pseudomonas
Topical of choice for electrical burns Suitable for open or closed method of treatment (cream)
Used for gram-negative organisms

Severe pain and burning sensation(lasts 30 min)
Metabolic acidosis
Carbonic anhydrase inhibitor
Ineffective against fungi
May cause hypersensitivity rash
Administer pretreatment
analgesic
Monitor for metabolic acidosis and hyperventilation Check for allergy to sulfa;
Check for allergy to sulfa;
observe for rash
Silver nitrate Lowcost
Broad spectrum
Effective with Candida
Continuous wet soaks
Superficial penetration
Black staining of sheets
Stinging
Electrolyte imbalances (low sodium, low chloride, low calcium, low potassium), alkalosis
Check serum electrolytes daily
Rewet dressing to keep moist
Petroleum and mineral oil-based (e.g.. Bacitracin, Neosporin, Polysporin) Bactericidal, gram-positive and gram-negative organisms Painless
Prevents drying of wound
Limited ability to penetrate eschar Apply in thin layer (1 mm) Reapply as needed.


Wound Coverings

Example Advantages Disadvantages Nursing Implications
Biological
Xenograph
Promotes healing of clean wound; relieves pain; readily available; reduces water and heat loss Easily digested by wound collagenase; allergic reactions Overlap edges slightly; trim away when skin underneath has healed
Homograft-cadaver skin Reduces water and heat loss; relieves pain; used with antimicrobial mesh; may be left in place until rejection occurs May harbor disease Observe for signs of infection
Amnion Relieves pain; reduces water and heat loss; has bacteriostatic properties Limited shelf life; requires special preparation for use; may harbor diseases Change cover dressing q48h; leave on wound until it sloughs
Biosynthetic (Temporary) Biobrane Protects from microbial penetration; decreases pain; promotes healing in partial-thickness burn Not effective for preparing a granulation bed Must be secured to skin with sutures, closure straps, tape, or staples; wrap with gauze; after 48 hr, check for adherence; once adherence has occurred, may be left open to air; check for signs of infection
Biosynthetic (Semipermanent)Integra Artificial Skin Postexcisional treatment of lifethreatening full or deep partialthickness burns when autograft not available Infection rate lower than autograft Maintain integrity of covering; 18-20 days before thin autograft applied. Avoid hydrotherapy; observe for infection.
