Wet to dry is just like how it sounds...start with sterile guaze and saurate a piece with saline and place it over the wound, you want it crumpled a little, not all flat , the next piece is wet, but wring it a little more, the next piece is moist, then cover with several dry pieces and wrap in place. You do not need to wash this wound as you remove the guaze it will self debrede, when you change the dressing. Keeping the wound moist will also aid healing as new cells can travel and fill in the hole faster. The outer layer is dry to prevent heat loss through evaporation from the surface area. Don't use hydrogen peroxide on any wound, or alcohol, it will merely cause pain and kill healthy cells, actually burning new tissue growth...the best cleaning is rinsing or irrigation with sterile saline. I like vetericyn spray..it works! I wouldn't care for any ointment inside a wound like that. Do w wet to dry and hold it in place with vet wrap...leave the feathers over the area to protect it...eventually it will draw close, more than you'd think.
