Flashcards in Wound phases Deck (22)
What are the phases of wound repair?
matrix synthesis and remodelling
What are the three intention healins?
1. 1st intention healing "golden period"
2. 2nd intention healing
3. 3rd intention healing or delayed primary closure
What are the features of 2nd intention healing?
tissue loss (debris/necrotic tissue)
What do you have to know about 1st intention healing?
2. wound characteristics
3. vascular supply
4. degree of contamination
How common are heel bulb lacerations?
What should you always do with heel bulb lacerations?
may find P1 and P2 fractures
may have entered multiple joints, nerves, arteries
tap appropriate jointse
What structures are near heel bulb lacerations?
1. tendon sheath
2. coffin/pastern/fetlock joints
3. navicular bursa
4. palpmar/plantar neruovascular bundle
What are the special issues with rope and wire burns?
there is latent heat!!
latent heat necrosis--don't know how bad it will be 7-10d post injury!
keep client expectations low
smooth wire cuts bad! may look ok but actually be bad
What is the issue with trauma around pastern joint?
horses don't tolerate wounds in this region very well
pastern osteoarthritis fairly common even if don't have break in skin
What are the benefits of bandages?
1. protects wound
2. reduces movement--less granulation tissue?
What is an issue with bandage?
drops oxygen, ups CO2 and causes increased granulation tissue
Why is it bad idea to put a bandage on a horse that is out in pasture with friends?
bandage slips, pressure sores etc
What is a disadvantage of no bandage?
does not reduce movement so may promote excessive granulation tissue formation
Why is bandage vs no bandage both acceptable?
can bandage frequently and keep animal in and have it heel faster or let out in pasture and will also heal without bandage
What are the benefits of cast? what are disadvantages?
1. little aftercare and not client dependent
1. more expensive intiitally
2. slightly increased risk
What are benefits and disadvantages of bandages compared to casts?
1. cheaper at initial outlay
2. reduced risk
1. time consuming
2. client dependent
What is the treatment of hoof avulsion?
May get into pastern, coffin joint (just avoid cutting into tendon because tendon is above the joints)
remove and put in foot cast
What must you not have with skin grafts in horsess?
1. no cracks or crevices in granulation tissue--debride
2. no infection (staph, strep)
3. no movement
What is a common method of grafts?
punch grafts to promote epithelialization instead of scar tissue formation
What is an issue with cold water hosing?
makes the tissue look grey and water logged because it is
Maybe don't hose 10-15min (too long)
Where do wounds heal well?
2. proximal limb
3. distal limb?
