Lets Make Every day count
A wound is a breach in the skin barrierWound healing is a complex process in which the skin (or another organ-tissue) repairs itself after injury.
Wound Healing Process
What are the 3 main wound healing phases?
- Inflammation (”cleaning phase”)
- Granulation (”building phase”)
- Re-epithelialisation (”roofing phase”)
Wound types and their background
Acute wounds
Surgical wounds
Donor sites
Burns
Traumatic wounds
Skin abrasions
Chronic wounds
Leg ulcers
Pressure ulcers
Diabetic foot ulcers
Some differences between acute and chronic wounds
Acute/surgical wound
- Short duration
- No underlying pathology
- Normal inflammatory stage
- Usually heals without complication
- Acute wound fluid supports cell proliferation but leakage of exudate under the dressing can lead to maceration
Chronic wound
- Not progressed in 4 weeks and not healed within 8 weeks of formation
- Underlying pathology or disease
- Prolonged inflammatory stage
- A variety of complications may arise
- Chronic wound fluid does not support cell proliferation
- Chronic wound fluid damages peri-wound skin
