Your doctor removed dead or unhealthy tissue (debridement) from your child's wound. How it was done depends on how severe the wound was.
Your child may have some pain and swelling around the wound. This should get better within a few days. Your child may have a bandage or a moist dressing over the wound. The doctor will let you know how long to keep it on and how often to change it.
How long it will take for your child's wound to heal depends on how serious the wound is and whether your child has any other health problems that may slow healing. Your child may need to have the wound debrided again.
