Study Notes
Immediate Wound Management
- Aims to reduce microbial load and prevent contamination.
- Unstable animals initially treated with copious irrigation using readily available solutions, like tap water.
- Cover wound with antimicrobial agent.
- Ongoing protection with a bandage until animal is stable for definitive care.
Wound Dressings
Alginate Dressings
- For wounds with moderate/copious exudates.
- Absorbs exudates and keeps wound moist.
- Improves autolytic debridement (dead tissue removal).
- Enhances granulation tissue formation.
- Examples: Curasorb Calcium Alginate, Kendall Wound Care.
Bioscaffolds and Synthetic Matrix
- Used for chronic, indolent wounds.
- Provides a scaffold for extracellular matrix development.
- Examples: Porcine small intestinal submucosa (SIS Oasis Wound Matrix; Smith & Nephew), hydrolyzed bovine collagen (Integra Matrix; Integra LifeSciences Corporation).
Chitosan
- Linear copolymer from chitin.
- Derived from crab shells.
- Rope/film dressings available, but commercial dressings not widely used.
- Hemostatic field dressings are available.
Growth Factors
- Used if wound is deficient in, or has excessive, target cells or mediators.
- Examples: Recombinant human platelet-derived growth factor (Regranex; Smith & Nephew), approved by the US Food and Drug Administration for diabetes-induced foot ulcers.
- Others include platelet-rich plasma (self-formulated).
Nonadherent, Semiocclusive Dressings
- For wounds with intact surfaces.
- Protects fragile epidermis.
- Non-hydrophilic, so not suitable for open wounds.
- Examples: Petrolatum-impregnated gauze (Curity), rayon/Teflon pads (Telfa), transparent polyurethane films (Polyskin II).
Antimicrobial-Impregnated Dressings
- Additional antimicrobial protection, especially in early wound management or infected wounds.
- Examples: 0.2% Polyhexamethylene biguanide (Kerlix).
Wound Protection
- Apply topical antimicrobial agent followed by a clean, dry bandage to prevent contamination and hemorrhage.
- Stabilizes wound, improving comfort and reducing further trauma.
- Remains in place until definitive treatment.
- May include gauze impregnated with 0.2% polyhexamethylene biguanide for additional antimicrobial protection.
Bandage Application Considerations
- Bandage placement can be challenging based on location or animal mobility (e.g., proximity to anus or external genitalia).
- Secure with tie-over bandages, tensioning sutures, adhesive drapes, or direct stapling.
- Tie-over/tensioning sutures reduce wound tension.
- Adhesive drapes create waterproof barriers and maintain wound moisture.
- Lycra body suits help with bandage retention and prevent self-trauma.
