1

T/F: The golden period of wounds in horses is the period of 

time where there is less than 10^5 bacteria per gram of tissue

FALSE! THERE IS NO GOLDEN PERIOD IN EQUINE WOUNDS!

2

What type of closure have you done if you close a wound 2 to 5 days after injury, but before granulation tissue production?

Delayed primary closure

3

What type of closure have you done if you close a wound 5 or more days after injury, and granulation tissue is present?

Secondary closure

4

T/F: Epithelialization starts IMMEDIATELY after wounding

TRUE

5

Collagen deposition begins ______ days after wounding

2 - 3 days

6

What is angiogenesis initiated by?

Decreased oxygen tension

Increased lactate

Decreased pH in the wound

 

7

The final scar after wounding is ______% weaker than original

15 - 50 % weaker

8

What is the best type of debridement in equine patients?

Sharp and autolytic

9

What is the best thing to use for wound lavage?

SALINE! (not dilute antiseptics)

10

T/F: Nitrofurazone is a good topical agent for treatment of wounds

FALSE! It is carcinogenic

11

_______ is the most common hypertonic saline dressing and 

is used for exudative or necrotic wounds

CURASALT

12

What is the best antimicrobial dressing for post-op wounds

to prevent infection

KERLIX AMD

13

What is the active antimicrobial agent of Kerlix AMD?

Polyhexamethylene Biguanide (PHMB)

14

T/F: Corticosteroids are good for reducing granulation tissue

formation in acute wounds

FALSE! NEVER USE CORTICOSTEROIDS

15

In the equine there are differences in healing based on

wound locations.

BODY wounds are more efficient at contraction ( ____ mm/day)

and

LIMB wounds are slow at contraction ( ____ mm/day)

Body (1 mm/day)

Limb (0.2 mm/day)

16

The best way to close a distal limb wound is with

___________ closure

PRIMARY closure (and tight bandages)

17

How do you treat proud flesh of a distal limb wound?

Resection + bandage + delayed secondary closure +/- skin grafts

18

Why does proud flesh occur?

Inefficient protracted inflammatory phase results in

excessive proliferation phase

19

T/F:

You must anesthetize when removing proud flesh

FALSE- exuberant granulation tissue is void of nervous tissue- it is just fibroblasts and capillaries and is not painful

20

What is the most important step in skin grafting?

Granulation bed preparation!

Determines if the graft will fail or not

21

What is the most common bacteria with granulation tissue

and grafting?

Pseudomonas

22

What is the most effective topical Abx therapy

against pseudomonas- the most common bacteria with

granulation tissue and skin grafting?

TICARCILLIN

23

A skin graft that remains connected to the donor site is called a

pedicle graft

24

This type of graft requires a dermatome

Split-thickness graft

25

What are the two steps that occur during revascularization

of a new graft and when do they occur?

Inosculation - 48 hours

Neovascularization - 4 - 5 days

26

In a horse, where do you harvest tissue for a punch graft?

Under the mane or the ventrolateral abdomen.

Must excise SQ fascia and fat!

27

For a punch graft, recipient holes are placed _____ mm apart

in a symmetrical pattern, and recipient holes

must be _______ than the donor holes

6 mm apart

 

Recipient holes must be smaller than the donor holes

28

T/F:

Full thickness sheet grafts resist trauma better than split thickness

grafts, but are much more fragile

TRUE

29

What is the purpose of meshing sheet grafts?

Allow the graft to cover a wound larger than itself AND

PREVENT FLUID from disrupting graft from fibrinous and vascular attachments

30

T/F:

Clean, healthy granulation tissue is needed at the

recipient site of a free graft

TRUE
