Skin Integrity & Wound Healing Flashcards
Refers to the process of stopping bleeding or preventing blood loss from damaged blood vessels. It involves a series of complex interactions between platelets, blood clotting factors, and blood vessel walls to form a clot and promote wound healing
Hemostasis
In hemostasis, blood vessels first ____, then ______
constrict
dilate
The initial stage of wound healing characterized by the body’s immune response to injury. It involves the release of chemical signals, such as cytokines and histamines, which attract immune cells to the site of injury. This phase helps to clean the wound, remove debris, and initiate the formation of new blood vessels to support the healing process.
Inflammatory phase
How long does the inflammatory phase of wound healing last?
2-3 days
The second stage of wound healing, during which new tissue is formed to replace the damaged or lost tissue. It involves fibroblasts, which produce collagen to strengthen the wound, and the formation of new blood vessels. Additionally, epithelial cells at the wound edges begin to multiply and migrate to cover the wound, promoting its closure.
Proliferative phase
How long does the proliferative phase last?
several weeks
The final stage of wound healing. During this phase, the newly formed tissue undergoes remodeling and maturation to improve its strength and functionality. Collagen fibers reorganize, becoming more organized and aligned, and the wound gradually gains strength. The process may take several months to years, and the final scar may continue to refine over time.
Maturation or remodeling phase
