What is seen in this image?
Granulation tissue
What is seen in this image?
Granulation tissue
What are the principal’s of wound care?
- prevent further contamination
- debride
- remove debris
- adequate drainage
- promote viable vascular bed
- Select method of closure
How should you manage wounds? (hint: what kinds of assessments/ steps must you have)
What are the parts of the patient assessment for wound care?
What is the first step in patient assessment for patients with wounds?
Assess hemodynamic stability/ correct any abnormalities.
What are the types of wounds ( wound assessment)
What is a clean wound classified by?
What is a clean- contaminated wound classified by?
What is a contaminated wound classified by?
What is a dirty/ infected wound classified by?
What are your initial approaches for wound care ?
What is lavage? What should you use this for/ what should you do?
Finish this phrase: “ Dilution is the ________ to _________
“DILUTION IS THE SOLUTION TO POLLUTION”
What is the goal of lavage? Can you over do it?
Never too much lavage
What are types of debridement of wounds?
- Surgical
- Chemical ( enzymatic)
- Mechanical (bandaging)
- Biosurgical
What is surgical debridement?
What is chemical debridement?
What is mechanical debridement?
What is biosurgical debridement?
What tissue should you debride?
What tissue should you not debride?
What is considered for your closure plan? What wound should we not close?
What is a wound healing by first intention?
What is a wound healing by third intention?
What is a wound healing by secondary intention?
What is a wound healing by secondary closure?
What is epithelialization? How would healing occur?
When is healing by first intention important? When is the wound closed? What are other characteristics of these wounds?
Best choice for healthy wounds in well-vascularized area.
How is this wound healing?
First intention
When should you surgically alter a fresh traumatic wound?
◦ Clean [surgical] or “fresh” traumatic wound after it’s been cleaned [clean-contaminated
What must you do to prepare a contaminated wound for closure?
What is the characteristics of third intention wound healing?
When is it best to have a wound heal by third intention? what are some examples?
When does a secondary closure occur?
When is secondary closure recommended for a wound?
infected or large wound
What must you do for a wound that will have secondary closure? What may you see?
When does a wound heal by second intention?
When is letting a wound heal by second intention ideal? What are some examples? ***** ask
What method of wound healing is occurring here?
Second intention
What is the most important to discuss with an owner in regards to their choices with wound healing? What should they know about wounds we let heal via second intention?
What is the golden period? What does this mean?
TRUE or FALSE: We should close all wounds after the golden period to prevent further infection.
FALSE - we do not close wounds after the golden period if we can help it -> infection is likely.
What are the factors you should look at when assessing tissue viability?
What are consequences of closing non viable tissue?
Closure of dead/ necrotic tissue.
What are the uses of bandaging?
What is the layers of bandages?
- Primary layer “ dressing
- Secondary layer
- Tertiary layer
How may layers are there to a bandage?
3
What is the purpose of the primary layer of a bandage? What material is typically used?
What is the purpose of the secondary layer of bandage? What material is typically used?
What is the purpose of the tertiary or outer layer of bandage? What material is typically used?
What is hydrophillic foam? What is its benefits/ characteristics?
What is the indications of use and the characteristics of the following topical agent: Granulated Sugar?

What is the indications of use and the characteristics of the following topical agent: Biologic (maggots)?
When should you use sugar in wounds? What is its benefits? How should you apply/ how often should you change it?
When should you use manuka honey in wounds? What is its benefits? What are the cons?
When should a drain be placed?
How many days do most drains remain in place?
3-7 days
What are the types of drains?
- Passive Drains
- Active Drains
What are passive drains? How do they work?
What are active drains? How do they work? What is an example?
Example: Pleuravac
What is seen in this image? Is it passive or active?
Penrose drain -> passive drain (works with gravity)
How are cuts/ tears (lacerations) typically managed?
How are degloving injuries typically managed?
How are puncture wounds typically managed?
How are abscesses typically managed?
How are open fractures typically managed?
What are some complications for wound healing?
- Seroma
- Infection
- Dehiscence
- Failure to heal
What is the preventative measures that are in place to help decrease incidence of seromas?
What is the preventative measures that are in place to help decrease incidence of infection?
What is the preventative measures that are in place to help decrease incidence of dehiscence?
What is the preventative measures that are in place to help decrease incidence of failure to heal?
In what kind of wound would you look to send the patient for an immediate surgical consultation?
Open Fracture
