26.5.3: Wound management Flashcards
1
Q
What are the 4 phases of wound healing?
A
- Haemostasis
- Inflammatory phase
- Proliferative phase
- Maturation/remodelling phase
2
Q
When does the inflammatory phase occur?
A
1-3 days after wounding; longer in horses and some wound locations
3
Q
When does epithelialisation start?
A
24-48hrs after wounding
4
Q
What inhibits epithelialisation?
A
- Infection
- Desiccation of wound
- Exuberant granulation tissue
- Repeated dressing changes
5
Q
Which wounds will heal faster: flank wounds or limb wounds?
A
Flank wounds
6
Q
What are the 2 subsections of the proliferative phase?
A
- Epithelialisation
- Contraction
7
Q
How does granulation tissue impact epithelialisation and contraction?
A
- Granulation tissue must be at the level of the skin (not above or below, otherwise the skin will not be able to cover the defect)
- Contraction cannot occur over proud flesh
Proud flesh = excess granulation tissue
8
Q
What can you clean a wound with?
A
- 0.05% chlorhexidine
- 0.1-0.2% povidone iodine
- Can just use water

Q
What joint are we sampling here? Where should the needle be?
A
- Distal interphalangeal joint (DIP) a.k.a. coffin joint via the dorsal perpendicular approach
- Needle should be midline or 1cm off midline (no more)
- Needle should be perpendicular to ground (when leg is weight-bearing)
