This paper provides a comprehensive overview of wound care from a nursing perspective. It defines wounds and wound healing, then systematically examines the four physiological phases of healing — inflammatory, destructive, proliferative, and maturation — along with the clinical, psychological, and organizational barriers that can impede recovery. The paper surveys common wound types, outlines principles of nursing assessment including comorbid factors and pain evaluation, and discusses appropriate dressing selection for different wound presentations. It concludes by emphasizing the critical role of thorough documentation in supporting care planning, legal accountability, and holistic patient management.

A wound can be defined as "the interruption of continuity in a tissue, usually following trauma. Skin is predominantly affected although any tissue, whether nerve, bone, or organ, may be wounded" (Definition of a Wound). In order to deal adequately with a wound, the professional nurse should have a comprehensive understanding of the process involved in wound healing. As one study emphasizes, "All nurses involved in wound management need to understand the wound-healing process, as this should underpin their care plans" (The Physiology of Wound Healing: An Emergency Response, 2002).
The various methods and approaches for dealing with a wound will depend on the type of wound and the stage of healing. However, the nurse must be able to identify the stage and type of wound in order to provide the most appropriate and effective treatment. The following discussion addresses not only the core aspects of wound healing but also explores some of the treatment processes involved in managing wounds.
Wound healing can be defined as "the physiology by which the body replaces and restores function to damaged tissues" (The Physiology of Wound Healing: An Emergency Response). There are a number of stages that must be identified as a prerequisite to treatment.
Identification of the stages and processes of a wound is an essential aspect of treatment. One important example is the ability to recognize the difference between the inflammatory phase of a wound and the signs of wound infection, so that the necessary treatment can be applied (The Physiology of Wound Healing: An Emergency Response, 2002). In other words, the entire physiological process — from the initial response through healing, regeneration, and complete closure — must be understood by the nurse or medical practitioner in order to make correct and timely treatment decisions.
The inflammatory phase is the physiological response to an injury. A number of physical responses are observable at this stage, including constriction of blood vessels, clotting, and the formation of a fibrin mesh over the wound that dries to form a scab (The Physiology of Wound Healing: An Emergency Response, 2002). The symptoms of this phase — redness, swelling, and pain — should not be confused with infection (The Physiology of Wound Healing: An Emergency Response, 2002).
The destructive phase of the healing process is the stage in which "the body clears away rubbish from the wound in the same way that debris will be cleared away after the fire-fighters have departed. White cells line the walls of blood vessels and migrate into the tissues ready to destroy invading bacteria" (The Physiology of Wound Healing: An Emergency Response, 2002).
The proliferative phase occurs after approximately one to three weeks and is the stage of active regeneration and construction of new tissue. This includes the synthesis of collagen and other connective tissue to repair the wound. The edges of the wound begin to draw together during this phase (Phases of Wound Healing).
The final maturation phase takes place once the wound becomes closed (Phases of Wound Healing). Physiologically, this phase "involves remodelling of collagen from type III to type I. Cellular activity reduces and the number of blood vessels in the wounded area regress and decrease" (Phases of Wound Healing).
Many factors can prevent or obstruct the wound healing process. These can include clinical, socio-psychological, educational, and organizational factors. Neglect is obviously one of the greatest barriers to healthy healing. The introduction of infection through ineffective treatment can seriously obstruct recovery. Pain and stress are also significant barriers; as one study notes, "Pain is an accepted feature of chronic wounds. It is known to cause distress to the patient, and this in turn can delay healing" (Pain-Induced Stress: A Barrier to Wound Healing).
Lack of education about the healing process can also be a serious obstacle, as without the knowledge needed to implement best practices, complications can arise. Beyond clinical issues such as high bacterial infection rates, socio-psychological factors — including apathy, depression, and lack of social support — must also be considered. Organizational barriers include inconsistent research findings and a lack of standardization in accepted practice (Flanagan).
