Study Notes
Wound Healing Phases
- Inflammatory Phase: Characterized by the release of chemotactic factors from the wound site, attracting immune cells to facilitate healing.
- Proliferative Phase: The first phase of normal wound healing, focusing on tissue formation and repair after inflammation subsides.
- Maturation Phase: Occurs last; involves reestablishment of tissue integrity, during which collagen is remodeled and wound strength increases.
Phases Following Hemostasis and Inflammation
- Proliferative Phase: Involves new tissue formation, angiogenesis, and re-epithelialization.
- Maturation Phase: Focuses on remodeling and strengthening of the newly formed tissue.
Factors Affecting Wound Healing
- Various factors such as infection, poor nutrition, medications, and underlying health conditions can interfere with the sequence of wound healing phases, leading to nonhealing wounds.
Wound Healing Timeline
- Typically, the inflammatory phase occurs within the first few days, followed by the proliferative phase lasting several days to weeks, and eventually transitioning to the maturation phase which can last for months to years.
Common Causes of Nonhealing Wounds
- Factors contributing to delayed healing include diabetes, chronic inflammation, compromised blood supply, and mechanical stress on the wound area.
