I found an injured hummingbird. If you know your local hummingbird rehabilitation agency, call them immediately. For their phone number, look in the phone book or ask your local animal shelter, zoo, parks department, or conservation agent. In the St. Louis area, call 314-426-6400 (Wild Bird Rehabilitation).
Edge of Wound- Monitoring Healing. In a wound that is healing normally, new skin cells are formed and added to the edges and the base until it closes up. In many chronic wounds, this does not happen and the wound fails to close. Reasons for this include abnormal skin cells at the edges and base of the wound, or inhibitory factors in the wound exudate (fluid). In Diabetic ulcers or Pressure injuries, the wound edge may be worn away or damaged (i.e. undermined) so that new skin cells cannot attach properly.
A laceration is a wound that occurs when skin, tissue, and/or muscle is torn or cut open. Lacerations may be deep or shallow, long or short, and wide or narrow. Most lacerations are the result of the skin hitting an object, or an object hitting the skin with force. Laceration repair is the act of cleaning, preparing, and closing the wound.
