Study Notes
Factors Impairing Wound Healing
- Excessive movement or local distension can lead to impaired wound healing due to mechanical stress on the healing tissue.
- Recent weight loss and nutrient deficiency negatively impact wound healing by reducing available energy and essential nutrients required for tissue repair.
- Impaired arterial supply, often seen in conditions like peripheral artery disease, can hinder wound healing by limiting oxygen and nutrient delivery to the injured area.
Types of Scars
- Hypertrophic scars extend beyond the original wound boundaries but may regress over time, occurring due to excessive collagen deposition during healing.
- Keloid scars are characterized by their firm, red, itchy, and elevated appearance, remaining within the injury boundaries, and do not regress spontaneously.
- Scar tissue formed over flexor surfaces of joints is common when wounds heal by secondary intention, often leading to contractile scars.
Characteristics of Scars
- Stretched scars are the result of excessive tension on healing skin, causing the scar to widen over time.
- Adhesion scars are characterized by fibrous bands that develop between internal organs and tissues, often leading to restricted movement or function.
