The stages of wound healing overlap and the wound can revert to a prior stage if damaged. This is why bioburden becomes important. Wound healing begins with coagulation. Once there has been an injury, the damaged tissue releases clotting factors which lead to the formation of a fibrin clot that will act as a scaffold.
Neutrophils enter early during the inflammation stage. Neutrophils destroy bacteria and recruit other inflammatory cells through chemotaxis. They are also responsible for breaking down debris and foreign material in the wound. These cells are present for a few days and then macrophages emerge in the wound.
Macrophages are vital in that they help convert the wound from an inflammatory state to a granulation state.
These cells are responsible for facilitating debridement of the wound as well as controlling fibroblasts and endothelial cells. The third stage of healing is the granulation phase.
In this phase, fibroblasts emerge and lay down extracellular matrix, setting the stage for angiogenesis. Epithelialization also takes place at this time. The final stage is the maturation stage.
At this point, the wound closes with fragile epithelium. The tissue deep to the fragile epithelium will begin to be replaced by scar tissue. This tissue eventually evolves into a sturdy avascular collagen scar. Scar tissue will initially have 20 percent strength of the original skin and will only advance to 70 percent of original strength. Differentiating between colonized and infected wounds is difficult at best.
Until we have more information on the exact definition of critical colonization and an objective measuring tool with which to measure the level and activity of bacteria in wounds, practitioners must rely on clinical observation to assist them in this difficult task.

Infection is the process where an infectious agent microorganism invades and multiplies in the body tissues of the host resulting in the person developing clinical signs and symptoms of infection E. Increased temperature, rigors, rash. Skip to main content. Basic Principles Introduction Infection prevention and control is the application of microbiology in clinical practice.
The chain of infection The process of infection can be represented as a chain, along which microorganisms are passed from a source to a vulnerable person. Opportunities to break the chain of infection Transmission may be interrupted when: The infectious agent is eliminated, inactivated or cannot survive in the reservoir E.
Hand Hygiene, appropriate use of PPE, safe packaging and disposal of waste Transmission does not occur due to good infection prevention and control practices E. Hand Hygiene, isolation of infected patients, air flow control where appropriate The portal of entry is protected E.
