Wound Management and Bandaging Flashcards
What is the first phase of wound healing?
The inflammatory phase.
What is the length of the inflammatory phase?
From when the wound is made to 3-5 days afterwards.
What form during the inflammatory phase?
Blood clots.
What are the functions of blood clots in the inflammatory phase?
- Control bleeding.
- Stabilize the wound edges.
What cells enter the wound during the inflammatory phase?
Inflammatory cells.
What is the function of inflammatory cells during the inflammatory process?
Removing bacteria and debris.
What is the second phase of wound healing?
The proliferative phase.
What is the length of the proliferative phase?
Begins 2-3 days after the wound was made and can last for weeks.
What types of cells enter the wound during the proliferative phase?
- Endothelial cells.
- Fibroblast cells.
What type of tissue fills in the wound during the proliferative phase?
Granulation tissue.
What is the function of granulation tissue?
To act as a barrier against infection.
When does epithelialization begin?
4-5 days after the wound was made.
How does epithelialization occur?
It starts at the edges of the wound and moves inward.
What is an overgrowth of granulation tissue called in horses?
Proud flesh.
How is proud flesh treated?
The overgrowth is sawed back down to normal level and the wound is wrapped in a bandage to promote healing.
What is the third phase of wound healing?
The maturation phase.
What is the length of the maturation phase?
Begins 3 weeks after the wound was made and can last for months.
What type of connective tissue is remodeled and realigned during the maturation phase?
Collagen fibers.
When the wound is fully healed, is it as strong as it was before the injury?
No, it will never be as strong.
During which phase of wound healing does the tissue around/in the wound regain strength?
The maturation phase.
What should be used to clean a wound?
Chlorohexidine solution (blue). A Chlorohexidine scrub cannot be used because it contains abrasive compounds.
How is hair removed from a wound that needed to have hair clipped out from around it?
Sterile lube is placed in the wound to catch the hair that would have fallen into the wound. The lube is also easy to clean up.
