Acute vs chronic wound
Acute wounds follow and timely and orderly healing process.
Expected to heal ex: surgical wound
Chronic wounds do not easily heal and return to normal appearance and function
Ex: pressure injury
Wound healing: primary secondary and tertiary intentions
- Primary intention: wound with little loss of tissue
Wounds heal with skin well approximated. Little risk of injection. Ex: surgical wound - Secondary intention: wounds involving tissue loss. Heal from wound bed up.
Open wounds that become filled with scar tissue. Higher risk of infection. Ex: pressure injury, burn, severe laceration. - Tertiary intention: delayed primary closure (intentional or unintentional)
Wound left open, then closes
Phase of wound healing
- Reaction- inflammatory response: begins minutes after injury till about 3 days
- skin red, controls bleeding, delivers blood and cells to injured area, epithelial cells to wound site - Regeneration- epithelial proliferation & migration: 3 to 24 days
Regeneration of tissue: fills wound via epithelialization
3. Maturation- reestablishment of epithelial layer & remodeling : up to 2 years Collagen fibers (scar tissue) continue to gain strength.
Serous
Cleary watery fluid (exudate)
Sanguineous
Bright red exudate
Indicates active bleeding
Serosanguinous
Blood mixed with clear fluid.
Pale, red and watery
Purulent
Green, yellow, brown, thick exudate.
How would you assess an acute wound?
All dogs don’t continuously play (with) Paul
- Wound appearance (size, shape, colour, edges approximated)
- Wound drainage (serous, sanguineous, serosanguinous, purulent)
- Presence of drains (Jackson-Pratt, hemovac, penrose)
- Closure of wound (staples, sutures, steri strips)
- Palpation of wound
- Pain
Describe a Jackson-Pratt drain (J-P)
A little bulb that acts as a suction device. Tube is placed directly in the wound, as fluid is suctioned it fills up the tube.
Describe a hemovac drain?
For larger wounds. Tube is placed inside person during surgery. The other end is circular device that creates suction to remove fluids
Describe a Penrose drain
Often used for head or neck surgeries. It’s a latex tube.
Tube is placed inside body, pin on top not attached to anything to prevent tube from slipping. Exudate comes out around tube, not from tube.
Skin around at risk for breakdown.
Usually an order to pull out 1 to 2 cm a day for healing
4 patterns of stitches
Intermittent: each stitch is tied
Continuous: one tie at the beginning and end
Blanket continuous: one tie at the beginning, tie at the end, loops through each stitch
Retention: reinforcement along the wound
You palpate a wound and it is extremely tender, red and warm to touch. What do you think?
Infection
How can you minimize pain when doing a dressing change for a wound?
Pre medicating
Administer analgesic 30 to 45 mins prior
Debridement:
Removal of damaged tissue or foreign objects from wound
How is nutrition linked to wound healing?
Optimal nutrition facilitates wound healing , maintain immune competence, which decreases the risk of infection.
Poor nutrition= delayed wound healing
What are the 3 layers of surgical dressings
- Contact layer (covers wound)
- Absorbent layer (reservoir for excess secretion)
- Outer protective layer (prevents external contaminates from reaching wound)
Purpose of wound dressing
Many People Think Men ShoulD Help
- Protect from microorganisms
- Aid in homeostasis
- Promote healing via drainage
- Protect patient from seeing wound if unpleasant
- Promotes thermal insulation
- Provides moist environment to promote cell migrating and growing
- Support/splints wounds
How do you clean wound and skin?
Saline solution. Use gauze, only once then throw out
Clean dirtiest to cleanest, wound being cleanest.
Irrigating a wound
Principles
Gets rid of debris and dead tissue to promote healing
- Fluid should flow out so wound bed is not furthered damaged
- Liquid should flow from least to most contaminated
- Use low pressure (larger syringe, lower psi)
How to prepare a client for a wound change
- Administer analgesic if necessary
- explain steps to lessen anxiety
- Gather all supplies before you begin
- answer all questions about procedure or wound
Why would you obtain a wound culture?
Ex: purulent drainage, increased pain, temp or drainage
And reason to suspect infection
How do you obtain a culture
- Clean wound thoroughly
- Swab healthiest looking tissue
- Rotate in 1 cm by 1cm area
- Apply pressure with swab to draw up fluid
- Put swab in sterile container and label.
Packing a wound principles
- pack to elimate dead space
- Should be loose, contacting all wound surfaces and at skin level
- Assess for tunneling/undermining
- Protect skin integrity around wound to avoid maceration
