Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. wound healing is depicted in a discrete timeline of physical attributes constituting the post-trauma repairing process. In undamaged
epidermis and dermis form a protective barrier against the external environment.
When the barrier is broken, a regulated sequence of biochemical events is set into motion to repair the damage. This process is divided into predictable phases: blood clotting , inflammation, tissue growth , and tissue remodeling. Blood clotting may be considered to be part of the inflammation stage instead of a separate stage.
Wound care encourages and speeds wound healing via cleaning and
protection from re injury or infection. Depending on each patient's
needs, it can range from the simplest
first aid to entire nursing specialties such as wound, ostomy, and continence nursing and burn center care.
Most common types of non-healing wounds:
Diabetic foot wounds/ulcers
Surgically created wounds
Highest risk of non-healing wounds:
Patients with Rheumatoid arthritis, lupus (SLE)
Dialysis and transplant patients
Patients with venous insufficiency who develop swelling in the legs and feet
Poor circulation in feet and legs
Classification of Wound Dressing:
Examples: Gauze, wool dressings, and plaster
Advantages: Protect the wound from foreign contamination, stops bleeding, covers the wound, absorb exudate, and provide cushion
