ch 48 skin integrity and wound care Flashcards
acute wound nursing care
require close monitoring (q 8 hr)
chronic wound nursing care
every dressing change
wound irrigation
mechanical -debrides necrotic tissue with pressure that can remove debris from wound bed without damaging health tissue
-19 gauge, 35 mL syrnge, 8 psi
debridement
removal of nonviable, necrotic tissue
-mechanical, autolytic, chemical, sharp/surgical
autolytic debridement
use of white blood cells and natural enzymens of the body
- use dressing that support moisture at wound surface
- -transparent film, hydrocolloid dressings
chemical debridement
use of topical enzyme preparation
-Dakon’s solution, sterile maggots
poor wound healing
shear force, friction, moisture, nutrition, tissue perfusion, infection, and age
nutritional status implementations
dietician, enteral, 30-35 calories/kg, increased caloric intake, vitamin (C) and mineral suppliments, increased protein (1.8g/kg/day)
comfort measures implementation
administer analgesic 30-60 min before dressing changes, careful removal of tape, gentle cleansing, careful manipulations of dressings and drains, careful turning and positioning
primary intention wounds abnormal
- incision line poorly approximated
- drainage present more than 3 days after closure
- inflammation increased in first 3-5 days after injury
- no epitheliazation of wound edges by day 4
secondary intention wounds abnormal
- pale or fragile granulation tissue, gran tissue bed excessively dry or moist
- purulent exudate present
- necrotic or slough tissue present in wound base
- epitheliazation not continuous; odor present; presence of fistulas, tunneling, undermining
primary intention normal healing
clean, well-approximated edges
7-10 days resurfaces w epithelial tissue and edges close
wound drainage
1 g of drainage equals 1 mL volume
types of drainage 4
serous
sanguineous
serosanguinous
purulent
moist applications advantages
- reduces drying of skin and softens wound exudate
- moist compress conform well to most body areas
- moist heat penetrates deep into tissue layers
- does not promote sweating or insensible fluid loss
dry applications advantages
- less risk to burns than moist heat
- does not cause skin maceration
- retains temp longer because no evaporation
evisceration treatment
total separation of wound layers
- emergent surgical repair
- place sterile gauze soaked in sterile solution over extruding tissues
- make pt NPO
- observe for signs of shock
transparent dressing
protects from shear and friction
traps moisture, providing moist environment
stage 1 pressure ulcer
surgical wounds healing by primary intention
remove dressings once drainage stops
wound healing by secondary intention
dressing material becomes a means for providing moisture to the wound or helping in debridement
6 purposes of dressings
- protects from contamination
- aids in hemostasis
- promotes healing by absorbing drainage and debridement
- supports or splints
- thermal insulation
- provides moist environment
hydrocolloid dressings
support healing in clean granulating woundsand autolytically debride necrotic wounds
-shallow to mod deep dermal ulcers (stage 2, 3)
hydrogel
gauze or sheet impregnated w water or glycerine-based amorphous gel
- partial to full thickness, deep wounds w exudate, necrotic, burns, radiation damage (stage 2, 3, 4)
- soothing for painful wounds
foam and alginate
large amount of exudate and wounds that need packing
-not to be used in dry wounds and require secondary dressing
stage 1
resolves slowly without epidermal loss over 7-14 days
stage 2
heals through reepithelialization
stage 3
heals through granulation and reepithelialization
stage 4
heals through granulation and reepithelialization
Vacuum-Assisted closure- VAC
device that uses applied localized negative pressure to draw edges of wound together (negative pressure wound therapy -NPWT)
bandages and binders 6 therapeutic benefits
- create pressure
- immobilize
- supporting wound
- reduce or prevent edema
- secure a splint
- secure dressings
goals and outcomes
intact skin integrity
signs of healing
maintains intact skin over pressure points
