Study Notes
Pathophysiology of Open Wounds
- A wound represents a loss of skin and tissue integrity
- Wound healing is a four-step process:
- Formation of a fibrin-platelet clot at the injury site
- Recruitment of white blood cells to fight infection
- Neovascularization and cellular proliferation
- Tissue remodeling
- Wound healing phases overlap and are influenced by endogenous and exogenous factors
- Initial response to injury: vasoconstriction (5-10 minutes), followed by vasodilation (30-60 minutes) with fluid and leukocytes migrating to the site
- Within 3-5 days: fibroblasts and endothelial cells proliferate forming granulation tissue
- Epithelialization begins when a sufficient granulation bed is present (usually 4-5 days after injury)
- Collagen deposition, and wound remodeling occur over time to strengthen the healing wound
Types of Wounds
- Abrasion: Partial-thickness epithelial injury from blunt trauma or shearing forces. Heals rapidly with re-epithelialization and minimal bleeding
- Puncture Wound: Penetration of an object into tissue. Characterized by small skin opening and deep tissue contamination
- Laceration: Sharp incision into deep tissue (muscle and tendons) with minimal peripheral trauma to wound edges. May result in devitalized tissue if the incised tissue is elevated or avulsed
- Degloving Injury: Extensive loss of skin and underlying tissue, often occurring on distal limbs due to roller or wringer-type injuries or scraping across a hard surface. May be immediate or delayed exposure of the wound bed. Anatomic degloving injury involves tearing of the skin and underlying tissue; physiologic degloving involves separated skin from subcutaneous tissue and blood supply, leading to delayed tissue necrosis
- Thermal Burn: Tissue damage from heat application. Classified by depth of injury: superficial partial (epithelial), deep partial (epithelial and partial dermal), and full thickness.
