For contaminated wounds, the recommended sequence is lavage first, then debridement, then a closure decision based on contamination level.
Lavage should be performed with tap water as a first-line option rather than saline, with povidone iodine lavage reserved for heavily contaminated wounds. Equine Veterina… Optimal lavage pressure is approximately 13 psi. Equine Veterina… For small animals, thorough lavage is required before any closure attempt in contaminated lacerations. MSD Vet Manuals
Debridement pads are recommended for wound preparation, and larval debridement is appropriate in selected cases. Equine Veterina… Hydrosurgery is recommended for acute contaminated wounds. Equine Veterina… In small animals, debridement should be completed as necessary prior to closure. MSD Vet Manuals
Closure decisions hinge on the degree of contamination. Uncomplicated lacerations that are not grossly contaminated are managed by complete closure in small animals. MSD Vet Manuals Wounds communicating with the gastrointestinal, urogenital, or respiratory tract with controlled spillage, or wounds with minor breaks in sterile technique, are classified as clean-contaminated. WSAVA Global Gu… Fresh traumatic wounds under four hours old, or those with significant spillage of gastrointestinal or urogenital contents, are classified as contaminated. WSAVA Global Gu… Grossly contaminated wounds or those with established infection are managed as open wounds rather than closed primarily. MSD Vet Manuals
Topical silver sulfadiazine is not recommended for acute wounds. Equine Veterina… Honey reduces the duration of some phases of wound healing and represents an evidence-supported topical option. Equine Veterina…
In complex cases with established septic joint involvement and resistant infection, a combination of arthroscopic lavage, surgical debridement, ultrasound-assisted wound therapy, and vacuum-assisted closure has achieved resolution, including complete fistula closure and return to soundness. Equine Veterina…
