Bandaging + Wound Types Flashcards
How would you treat an abdominal gunshot wound?**
Abdominal exploratory, close any leaking loops of intestine asap
What determines the severity/type of burn? (3 things)
Temperature of Heat Source (Temp)
Duration of Contact (Time)
Tissue Conductance (Tissue)
How long does it take before you can accurately classify a burn?
Several days
How many layers of bandaging are there? What are they? (Broadly speaking)
3 Layers:
Primary - Contact
Secondary - Intermediate
Tertiary - Outer
What are the 4 categories of Primary/Contact bandaging layers? When are they indicated? Drawbacks?
Adherent: for debridement, NOT used w/ granulation tissue, PAINFUL when removed
Non-adherent: maintains moisture, prevents dehydration, promote epithelialization, usually semi-occlusive
Semi-occlusive: maintains moisture, absorbs excess fluid
Occlusive: more rapid epithelialization, slow contraction, increase exudate, **can increase infection risk
With dog bites, what kind of abs would you want to use?
Anaerobic, gram +/-, clavamox
What kind of dressings are Tegaderm/Opsite? When are they used? Cons?
Semi-permeable film (adherent)
- used w/ granulation tissue
- keeps moisture/promotes epithelialization
- $$$
What kind of dressings are Adaptic/Xeroform? When are they used? Cons?
Semi-occlulsive non-adherent
Wide mesh gauze w/ petroleum
Early repair, w/ granulation tissue
CONS:
increased contraction
delays epithelialization
PAINFUL to remove
What kind of dressings are Release/Telfa Pads? When are they used?
Semi-occlulsive non-adherent
Polyethylene Glycol
Granulation tissue, NOT painful
What kind of dressing is Alginate? When is it used?
Nonocclusive to Semi-occulsive
VERY absorbent, good for effusion (forms a gel)
Often contains silver
What kind of dressings are Hydrocolloid/Hydrogel?
Occlusive non-adherent
What is the purpose of the secondary/intermediate bandaging layer?
Acts as the absorbent layer (blood, plasma, exudate, etc…)
Holds contact layer to wound (esp. if it’s a non-adherent dressing)
Prevents trauma/motion
What are the characteristics of secondary/intermediate bandages? How are they applied?
Should have capillary action + appropriate thickness (fluid collection)
Snug but not too tight!!
What is the purpose of the tertiary/outer layer of bandaging? What are some examples?
Keeps bandaging in place
Prevent contamination from env.
Roll Gauze + Elastikon or VetWrap
What are stirrups? How do you apply them?
Tape used to secure padding when applying a splint.
Apply prior to primary/contact layer, then apply after secondary/int.
When would you use a tie-over bandage? How is it applied?
Areas that you can’t apply traditional bandaging
loops w/ suture around wound -> apply contact layer -> umbilical tape to hold in place
What is VAC? What are the benefits of using this?
Vacuum assisted closure
Increased blood flow, granulation, epithelial migration, cell mitosis and decreased bacteria/edema
When is VAC contraindicated or more risky?
Wound malignancy
Exposed blood vessels/nerves/organs
Necrosis
Untreated osteomyelitis
Active Bleeding
Anti-coagulant Rx
Hemostasis
What is an abrasion?
Removal of skin that does not penetrate the entire dermis
