Bandaging an injured finger accomplishes two things. First, it protects the injury and promotes healing. Second, it stabilizes the injured appendage. If you get a cut or scrape, you can take care of your hurt finger with a simple, everyday bandage at home.
Apply a bandage to the wound. The type of bandage will depend on how severe the wound is. For a cut or a scrape, use a small, regular adhesive bandage. Lower the gauze piece over the wound and gently wrap the sticky ends around the finger. Make sure that the bandage is snug enough that it will apply some pressure to the wound but not tight enough that it cuts off the circulation. For a deep cut that will require stitches, apply a small butterfly bandage to keep the wound closed. Wrap a piece of sterile gauze over the butterfly bandage to keep the wound clean and secure with a piece of medical tape. Place a piece of sterile gauze over a puncture wound, burn, or a deep cut. Tape it securely with a piece of medical tape. For a sprain, wrap the injured area with an elastic fabric bandage (usually pinkish or brown). Place the bandage in a circular motion around the wrist or finger, and cover up part of the previous section on each new roll. Secure with the two metal clips that come with the bandage. Cut a circle into a moleskin bandage for blisters. Make sure the circle is big enough to completely cover the blister. Then, remove the adhesive and place over the blister.
Splint the area so that it does not move (optional). Make a splint by placing a Popsicle stick or slice of stiff cardboard under the injured finger and the finger adjacent to it. Both fingers should be held stiff and immobile against the splint. Wrap both fingers in a layer of sterile gauze. Secure firmly by wrapping in medical tape at either end of the splint. Make sure that the wrapping is snug, but not tight. You should still be able to feel your finger and it should not feel colder to the touch than your other fingers after you wrap it.
Take care when changing the bandage. Be gentle with the wound and be careful not to cause further injury. If you can see a lot of blood through the bandage, do not remove it. Simply apply another bandage or piece of gauze over it to prevent reopening the wound.
