Factors Affecting Healing of the Wound


by Your Marque Team

The Process of Wound Healing

Wounds are one of the top reasons that people come see the doctor. They appear as a result of injury, surgery, infection or accident and they vary in degree and severity. However, the basic process of wound healing is the same and contains three stages:

  1. Vascular – with immediate constriction and then dilation of increased permeability of blood vessels
  2. Cellular – when the white blood cells rush to the site of injury to fight the bacteria
  3. Repair – when regeneration of destroyed tissue occurs or scar may be formed

 

Intrinsic & Extrinsic Factors of Wound Healing

Many patients suffer from chronic skin wounds that are very painful and dangerous. The amount of time and level of healing is affected by several intrinsic (internal) and extrinsic (external) factors.

Intrinsic factors include:

  • Age – the major cell functions that are important in different phases of wound healing diminish as we get older. The epidermis, outer  most layer of the skin, becomes thinner with age and is more prone to injury
  • Diabetes Mellitus – this disease causes decreased blood supply and leads to peripheral neuropathy
  • Suppressed immune system – contributes to a longer and more complicated healing process
  • Skin with reduced sensation – more prone to injury and poor wound healing as patient is not aware that he or she is injured

Extrinsic factors include:

Intrinsic factors that affect wound healing can’t be changed and should be considered during the healing process, while the extrinsic factors can be controlled by the patient.
