final Flashcards
primary intention
all tissues, including the skin, are closed with suture material after completion of the operation
secondary intention
wound will be left open (rather than being stitched together) and left to heal by itself, filling in and closing up naturally. It will mean you need regular dressings to the area for up to six weeks, but the time to full healing depends on the size, depth and site of the wound
risk factors for wounds
- decreased LOC
- impaired mobility
- moisture/incontinence
- age
- medications
- friction/shear
pressure injury stage 1
- intact skin, local non-blanchable erythemia (redness) with change in temperature/firmness
stage 2 pressure injury
- partial thickness tissue loss showing viable, pink/red, moist with distinct wound margin
- intact or ruptured serum-filled blister
- slough/eschar NOT PRESENT
pressure injury stage 3
- full thickness tissue loss with just subcutaneous adipose layer exposed
- slough/eschar initially present
- healing wounds show granulation tisue
- rolled edges (epibole) may be visible in chronic wounds
pressure injury stage 4
- full thickness tissue loss, damage going through subcutaneous adipose layer; fascia, muscle, tendon, ligament
- slough/eschar initially present
- healing wounds = granulation tissue
- rolled edges
unstageable wounds
dry, stable eschar firm cap
OR
moist, boggy eschar cap
deep tissue injury
dusky, boggy, or discoloured area of purple, maroon, ecchymosis, or blood-filled blister
medical devicde injury
injury can have appearance of any one of the stages or be instageable or DTI
usually conforms to the pattern or shape of device
mucosal injury
injury can have appearance of any one of the stages or unstageable but itself is not staged
usually conforms to pattern or shape of device
when wound bed is covered with slough/eschar….
unstageable, once visible, can be restaged either as stage 3 or 4
can you back stage/reverse stages of pressure injuries?
NO
venous ulcers
leg ulcers caused by problems with blood flow (circulation) in your leg veins. Normally, when you get a cut or scrape, your body’s healing process starts working to close the wound. In time, the wound heals. But ulcers may not heal without proper treatment
arterial ulcers
painful, deep sore or wound in the skin of the lower leg or foot. The ulcer doesn’t heal as you’d expect an ordinary sore to heal. That’s because there isn’t enough blood flowing to the area. Blood supplies oxygen and nutrients to the tissues.
venous vs arterial ulcers
They often form on the lower extremities, such as the legs and feet. Arterial ulcers develop as the result of damage to the arteries due to lack of blood flow to tissue. Venous ulcers develop from damage to the veins caused by an insufficient return of blood back to the heart.
phases of wound healing
- inflammatory phase
- proliferative phase
- remodeling
inflammatory phase
hemostasis, clots form a fibrin, damaged tissue and mast cells secrete histamine = vasodilation, WBC
proliferative phase
new blood vessels appear, filling wound with granulation tissue, fibroblasts synthesize collagen
remodeling
maturation, can take up to 2 years
wound assessment
pain, size, bed, exudate, edge, odor, periwound skin
measuring wounds
length “head to toe” at longest point
width side to side at widest point
measure depth by sticking qtip in
tunneling/sinus tract
narrow channel or passage extending in nay direction from the base of the wound = dead space with potential risk for abscess formation
undermining
open area extending under intact skin along the edge of wound
