20 – Bandaging Flashcards
1
Q
What are the indications for bandages?
A
- Support suture lines
- Early wound management
- Management of granulation tissue
- Owner convenience
2
Q
What is the function of a bandage?
A
- Pressure
- Support
- Promote wound environment
- Aesthetics
3
Q
Pressure bandages
A
- Obliterate dead space
- Reduce limb edema
- Control hemorrhage
- *control granulation tissue
o Cause in increase=due to change in oxygen (lack of oxygen=more granulation tissue)
4
Q
Support bandages
A
- Mechanical
- Circulatory
- Immobilization
5
Q
Bandage weaning
A
- Some wounds get dependent on the bandage and you need to wean them off
- Variable timing
- *otherwise will get swelling!
6
Q
What is important to consider with the wound environment?
A
- pH and temperature effects
o differences in summer (hot=yeast infections) vs. winter - Topical medications
7
Q
Aesthetics of bandaging
A
- Functional
- Eye catching
- *important to be able to do it well and can have a big impact on your clients
8
Q
What are the characteristics of an ideal bandage material?
A
- Inexpensive
- Conformable
- Capable of desired function
- Free of particulate matter
- Inert
- Gas permeable
- Easily sterilized
- Aesthetically pleasing
9
Q
What are the three layers of bandaging? (construction and physiology)
A
- Primary (contact) layer
a. Dressing - Secondary (intermediate) layer
a. Padding
b. Absorption - Tertiary (outer) layer
a. Occlusive
10
Q
Primary layer
A
- Sterile
- Maintain wound contact
o Held in place with Kling gauze
o If no wound=likely don’t need to do a primary layer - Conduct exudate
o Capillary - Adherent or non-adherent
11
Q
Adherent primary layer types
A
- Dry-to-dry
- Wet-to-dry
- Wet-to-wet
12
Q
Dry-to-dry dressings
A
- Debridement
- Remove exudate
- Remove dead tissue
- Remove superficial granulation tissue
13
Q
Wet-to-dry dressings
A
- *put gauze with saline onto the wound (intent that the gauze will dry out (so goes from wet to dry))
o *Hypertonic saline (osmotic and apply moisture to gauze) - Debridement
- Reduces exudate viscosity
- Enhanced capillary action
14
Q
Wet-to-wet dressings
A
- Minimal debridement
- Enhanced capillary action
- Minimal adherence
- High fluid producing wounds
15
Q
Nonadherent primary layer types
A
- Occlusive
- Non-occlusive
16
Q
Nonadherent dressings: characteristics
A
- Gentle on tissue
- Occlusive
- Semi-occlusive
- Non-occlusive
17
Q
What is an example of a non-adherent dressing?
A
- Telfa
- +/- gauze 4x4 squares
18
Q
Secondary layer
A
- Absorption: capillary action
- Pressure distribution
- Support
19
Q
What are some examples of secondary layers?
A
- Quilt
- Sheet cotton
- Gamgee
20
Q
Quilt
A
- Machine washable
- Can be reused
- Hard to get as good of compression
21
Q
Sheet cotton
A
- Rolled up cotton that can be pulled apart
22
Q
Gamagee
A
- Layers of cotton like material
- Not as put together as a quilt but holds it’s integrity
23
Q
Tertiary layer
A
- Pressure application
- Pressure factor
o Only last <30mins without elastics
o 50% stretch for elastics - Protection from elements
24
Q
What are some examples of tertiary layers?
A
- Brown gauze: first and then 1 of the 3 below
o Will tear nicely=can’t put it on too tight - Vet wrap
- Lightplast: between a vet wrap and Elastoplast
- Elastoplast/elastikon
25
Tie-over bandage (stent bandage)
- Use in difficult to bandage areas
26
Vacuum bandage
- Adhesive steridrape
- Suction apparatus
- *second intention healing
27
Ventilated thermoplastic mesh bandages
- Can still have a bandage in place to support other tissues, but have access to the wound itself
28
Quilt and polo wrap example
- Proactively put them on to prevent edema
29
Light bandage/pressure bandage example
- Ex. heel bulb laceration
o Didn’t need a big compressive bandage, just wanting to protect it
30
Pressure bandage example
- Foal with contracted tendons to try and get the regions to relax
31
External coaptation
- More so in small animal
- Don’t really us stir-ups in large animal
