Wound Care Flashcards
Contamination
Microorganism on wound surface
Colonization
Bacterial growing in wound with no signs of infection
Critical colionizatoin
Bacerial growth causes delay in healing but no invasion of tissue
Infection
Bacteria invacdes soft tissue and causes systemic response
Surgical debridement
Removing necrotic tissue to help wound heal
Mechanical debridement
Nonselective removal of tissue adn debris.
Enzymatic debridement
Selective removal of necrotic tissue using collagenase
Biologic debridement
Using maggots to digest dead tissue
Examples of antiseptic/antimicrobials
Iodine
Silver
honey
Primary wound closure
After surgery.
Edges of wound connected by suture
Delayed primary wound closure
Wait 48 hrs to close as long as not infected
Secondary intention wound closure
Wound can’t be approximated so wound is left open to heal.
Needs dressing changes for up to six weeks
Split coverage graft
Portion of skin that contains both epidermis ann varying portion of dermis.
Full coverage graft
Composed of epidermis and all dermis and some subcutaneous tissue
Tissue flaps
Tissue transferred from donor to recepienc while maintaining its own blood supply
Dry gangrene
Blood supply of tissue is cut off (ischemia).
Tissue is becoming necrotic
Wet gangrene
Bacteria is in the tisssue
Area swells and drains fluid
Smells bad.
Spreads faster than dry gangrene
Arterial ulcers
Toes, heels, bony prominences
Punched out look
Well demarcated edges
Can lead to gangrene
Pain
Venous ulcer
Hx of veinous probs
Medial gaiter region of leg
SLoping edges
Edema
Venous ulcer treatment
Compression
Arterial ulcer treatment
Surgery for arterial insufficiency
Most common place for diabetic wounds
Plantar foot and toes
What to do for heel wound
Don’t remove eschar over wound because it help with healing
What to do with deep tissue injury
Offload pressure to the affected area
What to do for Pressure Wounds that are large or nonhealing
General surgeon or dermatologist for biopsy and possibly skin grafting
Lymphedema
Tissue swellling from accumulation of lymph
Usually on arms or legs
INfection is common
Lipedema
Excess fat accumulates in lower part of body.
Does not efffect hands or feet.
Infection is rare
Wound Vac
Moist environment.
Removes healing inhibitors.
Increases blood flow to wound.
Stimulates angiogenesis
Stresses wound to promote proliferation
Wound Vac Contraindications
Wound eschemia
Infection/necrotic tissue
Malignant tissue
Fragile skin
