Which puncture wounds are eligible for low-pressure irrigation?

• A. Uncomplicated clean punctures less than 6 hours old
• B. All punctures
• C. Punctures older than 24 hours only
• D. Punctures on the hand only

Answer: (A)

Low-pressure irrigation is best used for wounds that are clean, uncomplicated, and seen soon after injury. The goal is to flush out surface debris and reduce bacterial load without causing tissue injury, which is most achievable when the puncture is fresh and clean. When a puncture is less than six hours old and hasn’t shown signs of contamination or infection, gentle irrigation can effectively remove debris and help prevent infection. If the wound is older, especially beyond six hours, the risk of bacterial proliferation and infection increases, making low-pressure irrigation alone less appropriate. Hand punctures aren’t the sole determinant of eligibility, and not all punctures qualify—older or contaminated wounds require more extensive assessment and care.
