Lecture 17: Lacerations and Wound Management Flashcards
Where is the skin thickness on the equine body
Mane and tail
Skin tends to be thicker with ___ than young horses
Older geldings
Skin is thicker at the ___surface of the legs than the __surface
Extensor, surface
Head, neck and body wounds heal better than wounds on __
Extremities
Prolonged healing in wounds of the extremities is due to ___ (4)
- Reduced vascularity
- Increased infection
- Increased inflammatory response
- Reduce regional temperature
Equine cleavage lines are parallel to ___
Predominant orientation of collagen fibers
Wounds that are parallel to ___have less tension
Cleavage lines/ langer lines of tension
When possible incisions should be made parallel to ___
Cleavage lines
Distal limb wounds are below the ___
Carpus tarsus
What is the most important step in wound therapy
Wound assessment
What are the steps in initial wound preparation
- Aseptic/sterile conditions (joints) vs simple clean technique
- Apply sterile water soluble gel to wound before clipping
- Clip hair over and around
- Rinse gel and hair from wound with sterile saline
- Explore wound
Debridement is an effective way to reduce ___within a wound and minimize ___
Bacterial load, necrotic tissue
What is the #1 choice for debridement
Sharp
What is the least traumatic debridement technique to tissues
Autolytic
What is a major disadvantage to sharp debridement
Once tissue is removed, can’t put that back
What is the least traumatic sharp debridement tool and should be used whenever possible
Scalpel
What are the two critical components for lavage
- Solution used
2, delivery
What solutions are used for lavage
Non-cytotoxic solution- saline, vetericyn, lacerum
How do you deliver a lavage
Need appropriate pressure and volume without pushing dither into wound—> use 19G needle or Catheter attached to 35mL syringe
What is a wet-to-wet dressing more effective at removing than gauze
Necrotic tissue and causes less damage to epithelial cells
What is a wet-to dry dressing
Dressing directly on wound bed is moistened with saline, rest of bandage is dry
Absorbent secondary layers pull fluid from primary dressing
What is a disadvantage to wet to dry dressings
Primary dressing often dries out between changes, when removed get non-selective debridement
What should chemical debridement be used for
Very contaminated wounds because not-selective
What are 2 chemical debridement agents
Hydrogen peroxide, hypertonic saline
