Q

What do you do for synoviocentesis?

Q

How do you know if a synovial structure is involved with a wound?

A

stick needle on the opposite side and see if it comes out the other

ex. Wound on the medial side? sterilely prep, stick needle with sterile saline on the lateral side

Q

How do you wound debride an equine wound - autolytic?

A
  • moist wound healing
  • white blood cells and enzymes degrade necrotic tissue, leave healthy tissue alone

21
Q

What is a delayed primary wound healing with equine?

Study These Flashcards
A
  • close after a period of debridement
  • within 3-5 days of the injury
  • mild/moderate contamination
22
Q

What is a delayed secondary wound healing with equine?

Study These Flashcards
A
  • close after granulation tissue is present
  • excise exuberant granulation tissue first
23
Q

What is a second intention healing with equine?

Study These Flashcards
A
  • no closure
  • large wounds
  • chronic, contaminated, skin loss
  • after granulation tissue is present
24
Q

What is the purpose of draining closed wounds?

Study These Flashcards
A

important to prevent accumulation of exudate that will compromise closure

25
What materials for a closed drain?
Jackson-Pratt doesn't have to be ventral
26
What materials for an open drain?
Penrose must be placed at most ventral location
27
What are the constraints of a Penrose drain?
must be placed at most ventral location
28
How do you suture equine wounds?
minimal tissue reactivity, sufficient strength non-absorbable monofilament
29
What suture patterns for wound closure equine - non-tension?
simple interrupted
30
What suture patterns for wound closure equine - high tension?
vertical mattress and near-far-far-near
31
What are wound dressings for equine bandaging - gauze?
wet-to-dry bandages , debridement of heavily contaminated and exudative wounds wet gauze with saline
32
What are wound dressings for equine bandaging - telfa pad?
surgical wounds or sutured wounds - non-adherent, non-occlusive
33
How do you bandage equine limbs (direction, medial/lateral side)?
counterclockwise on the left limbs clockwise on the right limbs start on the medial side of the leg
34
Where do you put tension on the bandage?
as you pass over the dorsal cannon bone
35
What are the veterinary bandage supply steps?
telfa pad white gauze sheet cotton brown gauze vet wrap elastikon
36
What are the reusable bandage materials?
standing wraps, pillow wraps, no bows, quilts polo wraps, standing wraps
37
How do you bandage over joints?
- can do a stack wrap or center over the joint - minimize pressure over boney prominences - use gauze to pad the accessory carpal bone and point of hock
38
What does this diagram show?
carpal bandage
39
What does this diagram show?
tarsal bandage
40
What are these pictures showing?
splinting
41
What is splinting often made from?
often made of PVC pipe and duct tape or white tape proper padding is VERY important
42
How do you apply a foot bandage?
- wrap tight on the hoof, loose on the skin - may or may not have padding - LOTS of duct tape on the bottom of the foot
43
What are complications of bandaging?
- exuberant granulation tissue formation - pressure sores - "bandage bows"
44
What are "bandage bows"?
extensor or flexor tendon inflammation (no actual disruption of the tendon)
45
Bandaging ruminants most commonly involve the ________
foot procedures
46
How do you perform a claw block?
block goes on the **unaffected** claw
47
What are some bandaging ruminant differences?
watch out for the dew claws
48
What is proud flesh?
exuberant granulation tissue
49
What can happen if you bandage after granulation tissue is present?
hypoxia
50
What happens with involvement of synovial structures?
small, seemingly innocuous wounds can VERY serious requires immediate referral
51
What bone sequestrum?
dead, infected piece of bone non-healing wound
52
What is cellulitis?
severe edema in the limb associated with a relatively small wound - infection of the subcutaneous tissues requires aggressive therapy
