Understanding Chronic Wound Healing
Chronic wounds are generally known as non-healing wounds or complex wounds because they are not easy to be treated using normal healing process. The reason is that of the changes that usually occur within the molecular environment of such wounds that do not leave the body in a state in which healing process can take effect immediately. For example, low level growth factors and high level inflammatory cytokines are such states that give rise to septic infections while affecting the overall healing process. Chronic wounds differ from acute wounds in that chronic wounds do not move through the predictable healing stages, whereas acute wounds can be cured at a predictable rate whether they are traumatic or surgical.
Nursing professionals/practitioners need to understand the pathology of diseases and the process of wound healing completely in order to know which treatment would be the most suitable one for any particular wound and what might be the reason behind wound stalling. In case of acute wound healing process, the three main stages of treatment include inflammatory stage, proliferative stage, and remodeling stage. On the other hand, for the pathologic process of chronic wound healing, the main phases may include prolonged inflammatory phase, alteration of cell’s proliferation ability, deficiency in receptor sites related to growth, no initial bleeding for triggering cascade, and increase in proteases.
