In short, observing granulation tissue in the bed of the wound means that the wound is progressing from the inflammatory phase of healing to the proliferative phase of healing. Several important cellular developments are occurring.
In healthy stages of wound healing, granulation tissue is pink or red and uneven in texture. Moreover, healthy granulation tissue does not bleed easily. Dark granulation tissue can be a sign of infection , ischemia, or poor perfusion.
Granulation tissue is a vital component of the wound healing process, representing the proliferative phase where new tissue formation occurs. Understanding what granulation tissue is and its significance in wound healing is essential for healthcare professionals involved in wound management.
This topic reviews the mechanism of wound healing and repair, the role that granulation tissue plays in that process, the pathophysiology resulting in chronic wounds and persistent granulation tissue, and the clinical significance of granulation tissue.
Prolonged Healing Time: Wounds with hypergranulation tissue often experience lengthy healing times due to the impediment of the normal wound healing process. Hypergranulation tissue can delay wound closure and increase the risk of complications.
This activity reviews the evaluation and treatment of wounds and discusses the various wound healing phases, highlighting the role of the interprofessional team in evaluating and treating patients with a wound.
This is granulation tissue and is necessary for healing. New pink skin will grow from the edge to the center of the wound, over this granulation tissue. The whole process may take 3-5 weeks depending on the size and depth of the wound.
Granulation tissue forms in the proliferation phase of wound healing (Figure 1). Granulation comprises newly growing capillaries from the base of the wound and leads to the formation of new blood vessels (angiogenesis), which deliver nutrients and oxygen to the healing tissues (Mitchell, 2020).
During the proliferative phase of wound healing, new connective tissue or granulation tissue is formed concurrently with other healing processes, including re-epithelialization, neovascularization, and immunomodulation.
Granulation tissue is a highly vascular connective tissue and is essential to the final stages of wound healing, maturation, and remodeling. Maturation. The final stage of wound healing is the maturation phase, and includes collagen cross-linking, remodeling, and wound contraction.
