Card Set Information
lift skin on back of hand to check for hydration status
pre-albumin normal levels
malnuturition if <15 mg/dl
malnutrition if <3.5 mg/dl
18-20 day half life, so it's a better guage of long term nutrition than the pre-albumin with its 2 day half life
glucose fasting norms
indicates short term management of diabetes
glycosylated hemoglobin norms
indicates long term management of diabetes
capillary refill test -- looks for what? normal value?
normal refill is < 3 seconds
rubor of dependency test - how? norms?
elevate LE for 1 min so sole goes pale
lower it to neutral
should get red in < 15 sec
tests the arterial circulation
tibial systolic divided by brachial systolic
norm is 1.0
diameter of a worrisome melanoma
> 6 mm (pencil eraser)
side effect of antimicrobial agents (povidone-iodine, bleach, Dakin's, etc)
they can retard healing
so, shouldn't be used unless the antimicrobial effect is really desireable
gauze is contraind when?
over granulation tissue unless there's an intermediate nonadherent dressing
occlusive dressings are contraindicated when?
deep ischemic ulcers
full thickness burns
stage IV ulcers
alginates - work how?
derived from seaweed, they react with exudate to form a gel over the wound
when not to use alginates?
dry or lightly exudating wounds (bc alg can dry out the wound bed)
films for wounds
adhesive clear membrane
permeable to O2 and moisture vapor
impermeable to H20, bacteria, contaminants
cons of films
not for use on wounds with fragile surrounding skin or infected wounds
foams work how?
cushion and protect wound
hydrophilic (absorb moisture) on wound side, and hydrophobic on other side
hydrocolloid works how?
adhesive wafers that form gelatinous mass when they interact with wound
occlusive or semi-occlusive
absorbs min to mod exudate
protects partial thickness wounds
for partial or full thickness wounds with necrosis
conforms to wound shape to rehydrate wound
can be used with infection
absorb minimal amounts of exudate, letting some pass thru to a secondary dressing
impregnated w solution to promote granulation or inhibit bacterial formation
nonstretchable dressing impregnated with ointments
: Unna boot
used for venous insufficiency ulcers
dressings that promote autolytic debridement
continuous moist gauze
US setting to promote wound healing
low intensity, pulsed, 3x/week
e-stim for wound healing -- wha tkind of current?
high volt pulsed current
in e-stim the anode (positive pole) promotes what?
epithelial cell migration and reactivation of the inflammatory phase
in e-stim the cathode (negative pole) promotes what?
inhibit certain bacteria
vacuum assisted closing is indicated when?
wound isn't closing
lack of arterial perfusion
excessive exudate that can't be controlled with dressing
applied continuously, can be applied if there's an infection
cells common in inflam phase of dermal wound healing
neutrophils and macrophages
predominant cells in granulation formation/proliferation aka fibroblastic phase
fibroblasts synthesize what?
collagen, GAGs (glycosaminoglycans) and elastin
