Initial treatment for human bites causing lacerations?

Initial treatment for human bites causing lacerations?

• A. Copious irrigation, left open, prophylactic antibiotics (Augmentin)
• B. Immediate primary closure with sutures
• C. Topical antiseptic only
• D. Observation

Answer: (A)

Human bites bring a mixed oral flora into the wound, so the goal is to reduce bacterial load and prevent deep infection rather than seal the skin shut right away. The best initial approach is thorough irrigation and debridement, then leaving the wound open to heal by secondary (or delayed primary) closure rather than sewing it closed immediately. Starting broad-spectrum antibiotic prophylaxis is essential because oral bacteria, including Eikenella corrodens and anaerobes, are common culprits in bite infections; amoxicillin-clavulanate is a preferred choice because it covers these organisms well. Topical antiseptics alone don’t prevent infection, and watching the wound without antibiotics risks progression to infection. Immediate primary closure with sutures is typically avoided in bite wounds due to high infection risk, unless in very select clean cases, which is not the standard initial approach.
