Wound Classification IV Dirty infected corresponds to which scenario?

Wound Classification IV Dirty infected corresponds to which scenario?

• A. Old wound with retained devitalized tissue or a wound with existing clinical infection (purulence), or a perforated viscera
• B. An open wound with contamination
• C. Clean wound with no infection
• D. Fresh wound with no spillage

Answer: (A)

Wounds are classified by infection level and tissue viability, and the dirty/infected category reflects an established infection or devitalized tissue. When a wound is old and contains devitalized tissue or there is an existing clinical infection with purulence, or when a visceral perforation is present, the contamination level is high and the wound is labeled dirty/infected. This scenario matches that description: an old wound with dead tissue or current infection (purulence) or a perforated viscera, all signaling bacteria present with tissue breakdown and a higher infection risk, which requires more extensive debridement, drainage, and often antibiotic therapy. In contrast, an open wound with contamination fits the contaminated (or dirty-contaminated) level but not the dirty/infected category because it may involve bacteria but lacks established purulence or extensive devitalized tissue. A clean wound with no infection and a fresh wound with no spillage are both clean; they have minimal contamination and no ongoing infection, which is a lower severity than dirty/infected.
