A jammed finger is a finger joint injury from a direct blow to a straightened finger. A crushed fingertip occurs when a fingertip is caught in a door. Injuries to the nail bed usually need stitches.
How can I help my child?
Bruised, jammed, or crushed finger. Soak it in cold water for 20 minutes. Give acetaminophen (Tylenol) or ibuprofen (Advil) as needed for pain. Call the doctor if the pain doesn't improve in 3 days.
Torn nail. If the nail is almost torn through or there is a large flap of nail, use sterile scissors to cut along the line of the tear. Sterilize the scissors by cleaning them with rubbing alcohol. Don't tape pieces of nail in place because they will catch on objects. Soak the finger 20 minutes in cold water. Apply an antibiotic ointment and cover with a Band-Aid. Each day, remove the bandage and soak the finger in warm water with a pinch of salt. Call your child's doctor if you see any signs of infection.
Cuts. Wash the wound by scrubbing with soap and water for 5 minutes. Then apply pressure for 10 minutes with a clean cloth (sterile gauze if you have it) to stop bleeding. Protect with a Band-Aid.
Skinned knuckles (deep scrapes). Scrub the wound for 5 minutes with water and liquid soap. When the wound is clean, apply pressure for 10 minutes with a sterile gauze to stop any bleeding. Apply an antibiotic ointment and cover with a Band-Aid. Remove the bandage and clean the wound each day. Call your child's doctor if you see any signs of infection.
Call your child's doctor right away if:
The skin is split open and may need stitches.
Blood collects under a nail AND becomes very painful.
There is any dirt or grime in the wound you can't get out.
A crush injury has damaged the skin or fingernail.
A finger can't be opened and closed completely.
Call your child's doctor during office hours if:
The injury looks infected.
Your child is not using the finger or toe normally after 1 week.
You think your child may need a tetanus shot.
You have other questions or concerns.
