First Aid Treatment: Avulsion Injury

First Aid Treatment: Avulsion Injury

An avulsion injury is a serious injury that occurs when a soft tissue is forcibly torn away, either partially or completely. The organ commonly affected by this kind of injury is the skin. Medically speaking, an avulsion injury usually refers to surface trauma where all skin layers have been torn away, thus uncovering its underlying structures, such as, subcutaneous tissue, muscle, tendons, or even bones. It is likened to an abrasion, except in its more severe form, as body parts can be partially or fully detached from the body. Avulsion injury is typically caused by trauma.

First Aid Management for Avulsion Injury

  • If the patient is unconscious, check for the patient’s airway, breathing and circulation. If necessary, initiate CPR. Call localemergency number.
  • For small wounds where there is no damage to structures such as nerves, blood vessels and the like, wash the wound with water and soap. Pat it dry with a clean towel. Apply antibiotic ointment. There is no need to cover the wound.
  • For large wounds with bleeding, control bleeding by applying direct pressure on the wound until bleeding stops. Use a clean dressing or any absorbent cloth. If the cloth is soaked with blood, another absorbent cloth on top of the used cloth. Elevate the injured area.
  • In cases of stab wounds, do not remove the knife as this maycause more bleeding.
  • In cases of amputations, rinse the amputated body part and remove any dirty material that can cause contamination. Wrap the severed part in a clean, damp cloth and place inside a sealed plastic bag before placing inside a bag of cold water.
