If the vaccine status of a horse presenting with a wound is unknown, what needs to be done? What if you know the horse is unvaccinated?

Unknown: Booster with tetanus toxoid

Unvax'd:  Tetanus toxoid + Tetanus antitoxin

2

How much blood (%) does a horse have?

8-10% BW

3

When is the golden period of wounds in horses?

Does not exist in horses 

In other animals = period of time before there is less then 10^5 bacteria/g of tissue

4

What type of closure/healing is it if it occurs 2-5 days after the injury before granulation tissue is formed?

Delayed primary closure

5

What do you do if you anticipate complications due to dead space?

Place drain

6

If you anticipate flap necrosis upon closure of a large non-penetrating thoracic wound, what can you do?

Use flap as 'natural band-aid', debride and close 

Wait 3-5 days for tissue to declare itself 

Manage client expectations

7

What are the 3 phases of wound healing?

Inflammation/Lag 

Proliferative

Remodeling

8

What initiates (3 things) angiogenesis during wound healing?

Decreased O2 tension

Low pH (in wound)

High lactate 

9

What type of collagen is layed down during wound healing?

Type III (40%) which shifts to type I as wound remodels

10

What is the single most important factor for successful wound healing?  What are the 3 types of this?

Debridement

Sharp, Irrigation (hydraulic), Direct contact 

11

When lavaging a wound it is important to use the appropriate ______ and appropriate _______.

Volume

Pressure

12

T/F: Ointments are likely to slow the epithelialization of a wound. 

True

13

Which antimicrobial dressing contains the active agent PHMB to which microbes are unable to become resistant?

Kerlix AMD

Dr. Little's fav

14

Name these 5 joints

Tibiotarsal

Intertarsal

Fetlock

Pastern

Coffin

15

Which structure is indicated by the blue scribbles?

Collateral cartilage

16

What 2 structures are you concerned about with a pastern laceration?

Tendon sheath (of digital flexor)

Pastern joint

17

What structure are you concerned about with a puncture wound to the sole/frog?

Navicular bursa

18

What structure are you concerned about with a heel bulb laceration?

Coffin joint

19

What type of wound closure would you choose? 

Second intention (debride and bandage)

20

What type of wound closure would you choose given this occured a few hours ago?

Delayed primary 

(debride, lavage, banadage q24-48 hrs, then close)

21

Why do eyelid lacterations have to be repaired surgically?

Globe must stay protected (function of lid maintained) 

22

What must you ensure when closing an eyelid laceration?

Must align eyelid margin 

Protect eye from trauma during suturing

Keep suture from irritating eye when repair is complete 

Close in 2 layers (conjunctiva and skin)

23

Why would you use stent sutures when closing a lip laceration?

To minimize risk of pull through during healing

Also remember at least 2-layer closure

24

What is proud flesh? How is it treated?

Excessive granulation tssue

Tx: Resection and bandage, delayed secondary closure, skin grafts 

25

Excessive granulation tissue is most likely to occu in which of the following locations?

a. Metacarpus

b. Pectoral region

c. Thorax

d. Head and neck

a. Metacarpus

26

What is the single most important factor for a successful skin graft?

Recipient bed preparation

27

Which type of graft, full thickness or split thickness, will look better? Which has better survivability?

Full looks better

Split has beeter survivability

28

T/F: When preparing a punch graft, the recipient holes are made with a smaller punch biopsy.

True

29

What are the 3 main reasons for graft failure?

Infection

Hemorrhage (fluid accumulation)

Motion

 

30

What can you do to conform a split thickness sheet graft to an irregular surface? 

Meshing
