What increases risk of a wound infection?

Wound infection. Many factors which include: the type of wound; the circumstances in which the wound developed (especially traumatic wounds); the length of time that you had the wound; underlying illnesses like diabetes or poor blood flow; the lack of care of the wound. These are just a few of the major things that can increase the risk of a wound infection.
A little more. Anything that slows down healing increases risk. Keep the wound covered and away from open air, avoid toxic substances like peroxide, alcohol, and betadine. Avoid anti-inflammation medicines like Motrin and advil (ibuprofen) as inflammation is important in healing. Protect the wound from stress and trauma. Dressing changes every other to every third day to allow yourwound to do its thing.
