Study Notes
Wound Healing Phases
- The proliferative phase is characterized by fibroblast activity and production of collagen.
- Vitamin C is required by fibroblasts to produce collagen during wound healing.
Inflammatory Phase
- Platelets play a crucial role in the inflammatory phase by releasing chemical signals that attract white blood cells to the wound site.
- Common symptoms associated with the inflammatory phase include pain, redness, swelling, and heat.
- Itching is NOT a common symptom associated with the inflammatory phase.
Proliferative Phase
- The initial wound tissue formed during the proliferative phase is known as granulation tissue.
- Capillary loops play a crucial role in wound healing during the proliferative phase by providing oxygen and nutrients to the wound site.
Remodelling Phase
- The main characteristic of the remodelling phase is the reorganization of collagen fibers to increase wound strength.
- Myofibroblasts are responsible for wound contraction during the remodelling phase.
Types of Wound Healing
- Atraumatic wound healing aims to reduce the inflammatory and proliferative responses.
Wound Healing Timeline
- Maximal tensile strength in a wound post-injury is typically achieved within 3-6 months.
Compartment Syndrome
- Compartment syndrome is indicated by a pressure level within muscles of greater than 30 mmHg.
Pressure Sores
- The defining characteristic of pressure sores is tissue damage caused by constant pressure and lack of movement.
