What are the current recommendations for wound lavage, debridement, and closure technique in contaminated wounds?

Question

Accepted Answer

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. 1 Optimal lavage pressure is approximately 13 psi. 1 For small animals, thorough lavage is required before any closure attempt in contaminated lacerations. 4 Debridement pads are recommended for wound preparation, and larval debridement is appropriate in selected cases. 1 Hydrosurgery is recommended for acute contaminated wounds. 1 In small animals, debridement should be completed as necessary prior to closure. 4 Closure decisions hinge on the degree of contamination. Uncomplicated lacerations that are not grossly contaminated are managed by complete closure in small animals. 4 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. 3 Fresh traumatic wounds under four hours old, or those with significant spillage of gastrointestinal or urogenital contents, are classified as contaminated. 3 Grossly contaminated wounds or those with established infection are managed as open wounds rather than closed primarily. 2 Topical silver sulfadiazine is not recommended for acute wounds. 1 Honey reduces the duration of some phases of wound healing and represents an evidence-supported topical option. 1 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. 5 | Topic | Recommendation | Key Caveat | |---|---|---| | Lavage fluid | Tap water first-line; povidone iodine for contaminated wounds 1 | Optimal antiseptic concentratio
