Description of Procedure
There are different types of debridement. Treatment may include more than one step. Methods may be:
Surgery—often used on large, deep, or painful wounds. Tools will be used to remove dead tissue. Some wounds may need help to close after tissue is removed. To do this, some skin will be removed from another area of the body and placed on the wound.
Non-surgical—will use medicine or water to remove dead tissue. Medical whirlpool or syringes may be used to brush away dead skin. Wet to dry dressing is another option. A wet dressing is packed in the wound and left until it is dry. When the dry dressing is pulled away it will take dead tissue with it.
A medicine may also be used over the wound. It will help to dissolve dead tissue. It can also help the body heal the wound itself. All methods may need to be repeated several times.
How Long Will It Take?
Surgical debridement is the quickest method. Nonsurgical debridement may take 2 to 6 weeks or longer.
Will It Hurt?
There may be some soreness after the procedure. Pain medicine can help.
Average Hospital Stay
Most can go home the same day, unless they were already in the hospital.
It may take the wound many weeks to heal. Wound care will need to continue at home.
