Study Notes

Immediate Wound Management

Aims to reduce microbial load and prevent contamination.
For unstable animals, initial care may include copious irrigation with a readily available solution (e.g., tap water), antimicrobial application, and ongoing protection with a bandage.
This bandage remains in place until the animal is stable for more definitive wound management.

Wound Dressings

Alginate Dressings

Used for wounds with moderate to copious exudates.
Absorbs exudates and keeps the wound surface moist, enhancing autolytic debridement.
Promotes granulation tissue formation.
Example: Curasorb Calcium Alginate dressing (Kendall Wound Care).

Bioscaffolds and Synthetic Matrix Dressings

Used for chronic, indolent (slow-healing) wounds.
Provide a scaffold for extracellular matrix development.
Examples: Porcine small intestinal submucosa (SIS Oasis Wound Matrix; Smith & Nephew), hydrolyzed bovine collagen (Integra Matrix wound dressing; Integra LifeSciences Corporation).

Chitosan Dressings

Linear copolymer of linked β-glucosamine and N-acetyl-D-glucosamine, derived from chitin-rich crab shell.
Limited commercial availability as dressings; some hemostatic field dressings exist.

Growth Factor Dressings

Contain growth factors.
Used when the target cells or mediators are active or there's a deficiency/excess of these within the wound.
Examples: Recombinant human platelet-derived growth factor (Regranex; Smith & Nephew), platelet-rich plasma (PRP).

Nonadherent, Semiocclusive Dressings

Used for wounds with intact surfaces.
Protects fragile epidermis and prevents external contaminants.
Not appropriate for open wounds due to being non-hydrophilic and drying.
Examples: Petrolatum-impregnated gauze dressings (Curity nonadherent dressing; Kendall Wound Care), rayon or Teflon pads (Telfa; Kendall Wound Care), transparent polyurethane film (Polyskin II; Kendall Wound Care).

Antimicrobial-Impregnated Dressings

Secondary bandage layer providing additional antimicrobial protection in early/infected wound management.
Example: 0.2% Polyhexamethylene biguanide-impregnated gauze (Kerlix; Kendall Wound Care).

Wound Protection

After topical antimicrobial application, a clean, dry bandage protects the wound from further contamination and reduces hemorrhage.
Stabilizes the wound, improving comfort and potentially reducing further trauma.
Remains in place until definitive treatment.
Gauze impregnated with 0.2% polyhexamethylene biguanide can reduce existing microbial burden and resist further contamination.

Bandage Application and Security

Bandage application may be challenging due to animal movement or location (e.g., near anus or genitals).
Bandages secured with tie-over bandages, tensioning sutures, adhesive drapes, or direct stapling to surrounding skin.
Tie-over bandages/tensioning sutures reduce wound tension.
Adhesive drapes provide a waterproof barrier and maintain wound moisture.
Lycra body suits can maintain bandage placement and prevent self-trauma.
