Lesson 2 – Wound
Care & Bandaging
Unit – Veterinary Assisting II
Client…..
"I woke up one morning and my dog Nora looked like she had a baseball inside
her neck on the right side. There were no marks at all and all we could figure
was maybe a spider bit her. I took her to the vet and they lanced it and put in a
drain. She stayed the night at the hospital and came home the next day.
Stages of Wound Healing
1. Inflammatory Phase
• Immediately after wound
• Blood begins to clot
2. Debridement Phase
• 6 hours after wound
• White blood cells cause puss
3. Repair Phase
• Fibroblast form scar tissue (bright red because capillaries moving in)
• 3-4 days after wound
4. Maturation Phase
• Scar tissue gains strength
Factors Affecting Wound
Healing
•
•
•
•
Old Age
Poor Nutrition
Contamination
Infection
Care of Fresh Wound
1st – Lavaging – pump saline solution into wound
2nd – Debridement – remove hair and lube up
3rd – Wound Closure
4 Classifications of Wounds
1. Clean Wound
• Recent wound, low bacterial contamination
2. Clean-Contaminated Wound
• Started as clean, but too much time expired
3. Contaminated Wound
• Has bacteria and debris
• Clean before closing
4. Infected Wound
• Abscess
• Openly drained
4 Methods of Wound Closure
1. Primary Wound Closure
• Use suture within 6 hours (Golden Period)
• Clean Wounds
2. Delayed Primary Closure
• Excess debridement
3. Second Intention Healing
• Heal itself
4. Secondary Closure (third intention healing)
• Suture after debridement
Bandaging
• Protects wound
• Restricts movement
• Restricts bleeding
• Primary Layer
• Support and sterile gauze pad
• Secondary Layer
• Padding
• Tertiary Layer
• Protection – conform to animal
Chest / Abdominal Bandages
• Not too much pressure
Limb Bandages and Splints
• Tight, but not too tight
• Can lead to swelling
• Odor
• Coldness on tissue
• Leave 2 toes open to check
circulation
• Use Chew Guard spray to prevent licking
• Elizabethan Collar
• Robert Jones Bandage
• Use cotton rolls and roll gauze
• Used to immobilize limbs
Other Bandages
• Modified Thomas Splint
• Aluminum rods - support
• Ehmer Sling
• For hip diplacement
• Velpeau Sling
• Shoulder fractures
• Hobbles
• Pelvic Fractures
