Introduction to equine wound management Flashcards
What are the 4 phases of wound healing
Haemostasis phase
Inflammatory phase
Proliferative phase
Remodelling phase
when does the haemostasis phase occur
first 5-10 minutes
ends when clot is formed
when does the inflammatory phase occur
1-3 days after injury
List 4 things we can do to positively impact the inflammatory phase
debridement
irrigation
good haemostasis
adequate drainage
what does there need to be for epithelialisation to occur on full thickness wound
until bed of granulation tissue
what can inhibit epithelialisation
infection
desiccation of the wound surface
exuberant granulation tissue
repeated dressing changes
what happens in the proliferative phase of wound healing
filling of the wound bed with healing tissue (fibroblasts)
Fibroplasia
angiogenesis
when does contraction occur in proliferative phase
starts week 2 after injury - continues for several weeks
What are 3 advantages of contraction in proliferative phase
accelerates closure
increase cosmesis of scar
less need for epithelialization
describe the remodelling phase
Ends in formation of scar tissue one - two years later
Ensure strength, integrity and function of new tissue
List 4 aims of equine wound management
Full epithelialisation without scar formation
In as minimal time as possible
Without recurrence or risk of breakdown
And
As cost effectively as possible
List 6 ways that ponies are better at wound healing than horses
Ponies have a much more rapid wound closure - quicker more intense inflammatory phase
more resistant to infection
greater capacity for contraction
less wound dehiscence
fewer bone sequestrate
less exuberant granulation tissue
Is it acceptable to use tap water on a wound
Yes
List 3 things that determine the clipping area around a wound
soft tissue involvement
bone involvement
synovial
How much clipping around a wound do you need
5 cm away from wound
