Phases and Complications of Wound Healing
| Question | Answer |
|---|---|
| Haemostasis | This phase of wound healing occurs directly after injury. Blood cells at area of injury vasoconstrict and clotting factors are initiated to prevent the individual from bleeding out. |
| Inflammation | This phase of wound healing occurs 2-3 days after the injury. There is an influx of WBCs into the wound, release of growth factors and the wound fills itself in. |
| Proliferation | This phase of wound healing occurs several weeks after the injury. New tissue fills wound space through action of fibroblasts, capillaries grow across the wound, blood flow to new area and granulation tissue forms. |
| Remodelling | This phase of wound healing occurs up to 3 weeks after the injury and can last for years. New collagen tissue is deposited and remodelled. |
| Maceration | This complication is caused by overhydration and results to impaired integrity of the surrounding tissues. (think of possible causes) |
| Hematoma | This complication is characterized by a localized collection of blood outside of the blood vessels. This can lead to permanent deformation such as cauliflower ear. |
| Infection | This complication is the second most common healthcare associated infection. |
| Dehiscence | This complication is characterized by a partial or total separation of layers of a wound. It becomes serious if it leads to evisceration. |
| Evisceration | This complication is characterized by organs protruding through separation and this is a surgical emergency. Abdominal injuries can lead to this. |
